Types Of Pipe Fittings Used In Piping

If the 3 sides of T-fitting are similar in size then it is called as Equal tee otherwise it is called as Unequal tee. The advantages of this method are durability, speed, neatness, and safety. Some crimped fittings are designed to be used with copper tubing, without requiring flux or filler metal. Although crimped fittings are suitable for drinking-water pipes and other hot-and-cold systems , they are substantially more expensive than sweated fittings. Where many connections must be made in a short period of time , soldering is quicker and less expensive joinery than compression or flare fittings.

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.

Here is a brief overview of pipe fittings, their purpose, and the materials offered. In this type of flange, the stub is butt welded to the pipe, whereas flange is freely moved over the stub end. It is basically flange part but covered under ASME B16.9 that is why it is considered as pipe fittings. You can see the chart above that lists most widely used standard pipe fittings.

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.

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.

Increase the length or join solvent weld pipe together with Magicflex solvent elbows and connectors from Wirquin. All our solvent weld connectors can bend and stay fixed when welded.

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.

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.
