A reducer reduces the pipe size from a larger to a smaller bore . Alternatively, reducer may refer to any fitting which causes a change in pipe diameter. This change may be intended to meet hydraulic flow requirements of the system or adapt to existing piping of a different size. The length of the reduction is usually equal to the average of the larger and smaller pipe diameters.

When compared to other connection types, press fittings have the advantages of installation speed and safety. Pressing a stainless steel fitting can be completed within 5 seconds with the correct equipment.

It must be installed in an easily accessible place for adjustment, replacement, and repair. A trap primer, a specialized valve, is usually connected to a clean-water supply in addition to a DWV system. Because of the dual connection, it must be designed to resist the accidental backflow of contaminated water. Underground piping systems for landscaping drainage or the disposal of stormwater or groundwater also use low-pressure gravity flow, so fittings for these systems resemble larger-scale DWV fittings.

A reducer can also be used either as a nozzle or diffuser, depending on the mach number of the flow. Dielectric unions, with dielectric insulation, separate dissimilar metals to prevent galvanic corrosion. When two dissimilar metals are in contact with an electrically conductive solution , they form an electrochemical couple which generates a voltage by electrolysis. When the metals are in direct contact with each other, the electric current from one to the other also moves metallic ions from one to the other; this dissolves one metal, depositing it on the other. A dielectric union breaks the electrical path with a plastic liner between its halves, limiting galvanic corrosion.

Take a look at our comprehensive ranges for effective plumbing and Gas Safe installation below. The information on those websites is not provided by Steel & Tube. Tighten the union nut until the point at which it becomes noticeably more di cult to turn the union nut. At this point, for example, minor damage on the thread caused by the union nut getting caught must be overcome.

Compression coupling is regular coupling which is connected between two pipes and it prevents leakage by the arrangement of gaskets or rubber seals on both sides, otherwise glue is provided. Slip coupling is easier to install and it contains two pipes which are arranged as one into other, inner pipe can slide up to some length. Flanges are rated at 150, 300, 400, 600, 900, 1500, and 2500psi; or 10, 15, 25, 40, 64, 100, and 150 bars of pressure. Various types of flanges are available, depending on construction.

The pressure losses that inevitably occur in pipeline systems can be recorded either by measuring equipment or by calculation. In order to achieve an optimum seal, conical screw-in threads must be provided with an additional sealing means, e.g., Teflon tape. Flare fittings were originally developed for high pressure applications and are used widely in locations that are exposed to strong vibrations. As the cutting ring moves along a precisely de ned assembly path, its cutting edges are forced into the surface of the hydraulic pipe.

The use of miter bend is restricted to the low-pressure water line. Applications include rotary and pipe fittings, adapters and couplings, hydraulic pipes and high pressure flanges. Whether you’re simply stocking up on plumbing fittings and repair parts or have a specific project in mind, Ace offers many types of pipe fittings made of different materials. Find your plumbing fitting solutions at Ace, then shop for other essential plumbing repair parts for your home needs. Coupling are also useful if the pipe is broken or leakage occurs.

The larger-diameter hub was also called a “bell” because of its shape. Adequate ventilation is essential to remove metal fumes from welding operations, and personal protective equipment must be worn. Because the high temperatures during welding can often generate intense ultraviolet light, dark goggles or full face shields must be used to protect the eyes.

There are three pieces in a union, a nut, a female end, and a male end. When the female and male ends are joined, the nuts provide the necessary pressure to seal the joint. Cap is a type of pipe fitting which function is same as plug but the only difference is plug contain male threads and cap contain female threads which is screws on the male thread of pipe. These are available in different materials like rubber, copper, steel, plastic etc. They are typically made of brass or plastic, but stainless steel or other materials may be used.

In Concentric reducer which is also known as a conical reducer, the center of both the ends is on the same axis. When the center lines of the larger pipe and smaller pipe are to be maintained the same, then concentric reducers are used.

The radius of curvature of a long-radius elbow is 1.5 times the pipe diameter, but a short-radius elbow has a radius equal to the pipe diameter. Short elbows, widely available, are typically used in pressurized systems, and in physically tight locations. 90 Degree elbow is installed between the pipe to change the direction of the pipe by 90 Degree.

Major pressing of fittings to pipes or other fittings is performed using electrically powered press equipment, but mechanically driven press equipment is also available. Most of the major brands further have a plastic slip on the end of the press fittings allowing a simple identification if a press fitting has securely been installed. Further, the installation does not use any welding; press fittings with appropriate and region specific certification may be installed for gas lines.

Although reducers are usually concentric, eccentric reducers are used as needed to maintain the top- or bottom-of-pipe level. Gaskets are mechanical seals, usually ring-shaped, which seal flange joints. Commonly used gaskets are non-metallic (ASME B 16.21), spiral-wound (ASME B 16.20) and ring-joint (ASME B 16.20). Non-metallic gaskets are used with flat- or raised-face flanges. Spiral-wound gaskets are used with raised-face flanges, and ring-joint gaskets are used with ring-type joint flanges. Stress develops between an RTJ gasket and the flange groove when the gasket is bolted to a flange, leading to plastic deformation of the gasket.

To an uneducated homeowner, pipe fittings are as numerous and confusing as choosing the right screw or nail for a construction project. The materials vary and the specific purpose, although precise, seems daunting to figure out. Our plumbers in Houston & Rosenberg can help repair or repipe your yard. We can help repair and repipe gas lines and water lines, whatever you need, our plumbers can help!

Half Coupling is used for small bore branching from a vessel or large pipe. Returning elbows are used to make a 180º change in direction. Returns are used in the heating coil, heat exchanger, tank vent, etc. These Fittings are available in a different types of end connections. And when you need to test the pressure of your pipes, our selection of test plugs proves to be a reliable option. Basically, the laws implemented Jan. 1st, 2014 require plumbing products that come in contact with drinking water to be “essentially lead free” (less than 0.25% weighted average).

Lightly oil the cone of the screw sleeve and the thread of the union nut. With sealing cone screw-on fittings with O-ring (AOL / AOS), the pre-stressing of the O-ring must be bridged and the sealing cone must lie metallically flush against the cone of the HL/HS connector. At this point, the cutting ring may be allowed to rotate, but must not move axially. Tightening torques for stainless steel fittings and for fittings with UN/UNF threads available upon request. The entire fitting consists of the threaded connector, the spacer ring with O-ring seal, the pressure ring and the union nut.

With high peak-flow volumes, the design and construction of these systems may resemble those of storm sewers. Never let that be the case with our selection of copper tubes, stainless steel tubes and different plastic pipe options. Long radius pipeline bends are used in fluid transportation lines which required pigging. Due to their long radius and smooth change of direction, the pipe bend has very less pressure drop, and a smooth flow of fluid & pig is possible.

Pipe fitting product line includes a large number of fitting types that surpass the requirements of this standard. In these special forms, e.g., pipe fittings with spring-back tolerances, the connector dimensions have been adapted to the pertinent standard, so that they can be replaced at any time. There are various pipe fittings available, each with their own unique function. The materials used in plumbing has changed over the years so we’ve made sure that we offer a comprehensive enough range to cater for both old and new installations. You’ll find pipe fittings from leading brands like JG Speedfit, Plumbsure and Fluidmaster that cover a wide range of fitting types. A nipple is a short stub of pipe, usually male-threaded steel, brass, chlorinated polyvinyl chloride , or copper , which connects two other fittings.

A tee, the most common pipe fitting, is used to combine or divide fluid flow.Tees can connect pipes of different diameters or change the direction of a pipe run, or both. Available in a variety of materials, sizes and finishes, they may also be used to transport two-fluid mixtures. Tees may be equal or unequal in size of their three connections, with equal tees the most common. In short radius elbow, centreline radius is the same as the nominal size of the pipe or you can say one times the diameter of the pipe.

Fasteners commonly used with piping are a stud bolt with nuts ; a machine bolt and nut; or a powder-actuated tool fastener . This fitting (also known as a “bungalow fitting” or a “cottage fitting”) is a sanitary tee that allows two trap arms to be connected at the same level. Clean-outs are fittings with removable elements, allowing access to drains without the removal of plumbing fixtures.

Our range of pipe tools also includes press fit tools to help with quick jobs on site. These fittings are used for small bore and low-pressure piping. 2000 class fittings are available in only in threaded type. Reducing coupling is used to connect two different sizes of pipe.

Elbows are generally available with an angle of 22.5o, 45o and 90o. If pipes are of same diameter then normal elbows are used otherwise Reducer elbows are used. These are generally coming with female threads and we can fix them by butt or socket welding also. Obviously, pipe fittings are attached to the end of pipes that allow them to change direction, control the flow, and change the diameter of the pipe. Being a non-trivial part of plumbing and piping systems, consulting us with your need is definitely advised to save yourself time, money, materials, and headaches. Unions are used as an alternative to flanges connection in low-pressure small bore piping where the dismantling of the pipe is required more often.

Precautions must also be taken to avoid starting fires caused by stray sparks and hot welding debris. Central vacuum system inlet fittings are intentionally designed with a tighter radius of curvature than those of other bends in the system. If vacuumed debris becomes stuck it will jam at the inlet, where it is easy to find and remove. A double-tapped bushing is more compact than a reducer, but not as flexible. While a double-tapped bushing has a smaller female thread concentric to a larger male thread , a reducer may have large and small ends of either gender.

Wye tee allows one pipe to be joined to another at a 45° angle. This type of tee reduces friction and turbulence that could hamper the flow. A barred tee which is also known as a scrapper tee is used in pipelines that are pigged. The branch of the tee has a restriction bar welded internally to prevent the pig or scrapper to enter the branch. The bars are welded in the branch in a way that it will allow restriction free passage of the pig from the run pipe.

Pipe welding is often performed by specially licensed workers whose skills are retested periodically. For critical applications, every joint is tested with nondestructive methods. Because of the skills required, welded pipe joints are usually restricted to high-performance applications such as shipbuilding, and in chemical and nuclear reactors. Although they are usually used to attach pipe and fittings to mechanical supports in buildings, they do not connect the pipes to each other.

Fittings for central vacuum systems are similar to DWV fittings, but are usually of thinner and lighter construction because the weight of the materials conveyed is less. Vacuum-system designs share with DWV designs the need to eliminate internal ridges, burrs, sharp turns, or other obstructions which might create clogs. Non-return or check valves allow free flow of a fluid in one direction, but prevent its flow in a reverse direction. They are often seen in drainage or sewage systems, but may also be used in pressurized systems. Isolation valves are used to temporarily disconnect part of a piping system, to allow maintenance or repair, for example.

PTFE tape and pipe joint compound (also known as “pipe dope”) should only be used on “IPS” (“iron pipe size”) threads, which are normal pipe threads. IPS threads make their seal along the threads themselves; when a piece of IPS-threaded pipe is screwed into a fitting, PTFE tape and/or pipe dope is used to assist that seal on the threads. Flare fittings, on the other hand, seal on the beveled ends of the fittings, and so using pipe dope or tape on flare threads could actually prevent the fittings from making an adequate seal. The chief advantage of these connectors is that they can be installed after cutting the pipe to length in the field. This can save time and considerable expense compared to flange connections, which must be factory- or field-welded to pipe segments. However, mechanically fastened joints are sensitive to residual and thickness stresses caused by dissimilar metals and temperature changes.

If both ends are the same gender, it is a gender-changing reducer. Insulating pipes is important when you’re working with refrigeration and heating systems. We stock Class O, plumbing pipe and lagging to help with insulation in all scenarios. In Eccentric reducer, the center of both ends is on different axis as shown in the image. When one of the outside surfaces of the pipeline is to be maintained the same, eccentric reducers are required. It is a type of Tee that has the branch at a 45° angle, or an angle other than 90°.
