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.

A nipple with continuous uninterrupted threading is known as a close nipple. Miter bends are not standard pipe fittings they are fabricated from pipes. Usually, they are preferred for size 10” & above because large size elbow is expensive.

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.

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.

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 .

In a long radius elbow, the centreline radius is 1.5 times the nominal size of the pipe or you can say 1.5 times the diameter of the pipe. Normally long radius elbows are used in piping as pressure loss is less as compared to short radius elbow. Elbows are available in two radius types, Short radius and Long Radius (1.5D).

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 CPVC fittings we offer will not glue on PVC schedule 40 pipe. The CPVC fittings we offer are Copper Tube Sized and normal Schedule 40 PVC pipes are sized according to IPS standards which are slightly larger in diameter. CTS sized piping has the same outside diameter as copper piping. 1/2″ Schedule 40 PVC fittings fit PVC piping that is 27/32″ O.D. Disassemble the pipe or threaded connection and check that a clearly visible shoulder of cut material is present in front of the first cutting edge. In this case, the cutting ring may be allowed to rotate, but must not move axially.
