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.
It is like a concentric reducer that maintains a centerline of the pipe but small in size. A pipe tee is used for distributing or collecting the fluid from the run pipe. It is a short piece of pipe with a 90-degree branch at the center.
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.
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.
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.
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°.
A closet flange is a specialized flange designed to be flush with the floor, allowing a toilet to be installed above it. The flange must be mechanically strong to accommodate slight misalignments or movements, and resist corrosion. Caps, usually liquid- or gas-tight, cover the otherwise open end of a pipe. The exterior of an industrial cap may be round, square, rectangular, U- or I-shaped, or may have a handgrip.
Fittings require money, time, materials, and tools to install, and are an important part of piping and plumbing systems. Valves are technically fittings, but are usually discussed separately. Choosing the material of your pipe fitting comes down to what will be running through the pipe. From fittings perfect for cold water supplies to reliable options for gases and chemicals wastes, we carry a variety of fitting options to help you get the job done.
We maintain deep inventories of stainless steel fittings to provide quick shipments. These disadvantages are less problematic for fire sprinkler installations, because standing water in the steel pipes does not flow, except during occasional tests or actual activation by a fire. The introduction of oxygen dissolved in fresh supplies of water will cause some corrosion, but this soon stops in the absence of any source of further water-borne oxygen. Threaded steel pipe is widely used in buildings to convey natural gas or propane fuel, and is also a popular choice in fire sprinkler systems due to its resistance to mechanical damage and high heat .
