We offer more detailed information about NPT pipe threads here. Choose from our extensive range of plumbing pipes and fittings including the pushfit system of valves and connectors, as well as brass and copper compression fittings. Whether you’re on-site or fitting piping domestically we have only the best plumbing and pipe fittings, in numerous pack sizes for you to use. Various types of pipe fittings are available in plumbing systems for different purposes and functions. A pipe fitting is used in plumbing system to join multiple pipes of same size or different sizes, to regulate the flow or to measure the flow.
They are used to connect pipework together and form angles. Plumbing fittings come in various different types to reduce the flow size from larger to smaller or to change the direction of flow between two pieces of pipework. Choose from metal or plastic fittings and various pack sizes.
It should be noted that this safety factor is contingent on error-free assembly and correct routing of the pipeline system. Information about ttings often includes the nominal pressure, designated PN. The nominal pressure, PN, is merely an index that serves as an identi er or designator for a part or system. When the assembly instructions are followed, repeat ttings can be carried out safely and reliably.
A specially shaped limit ridge prevents overtightening, the pipe material that is raised in front of the edges is cold-hardened. Our team’s focus is to provide the solutions you need to succeed and grow. This included adding products based on items you are searching for, offering rewards for your purchases & business advantage memberships with discounts built into your online account.
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 .
Flanges used in piping (orifice, threaded, slip-on, blind, weld neck, socket, lap-joint, and reducing) are available with a variety of facings, such as raised, flat, and ring-joint. A barb , which connects flexible hose or tubing to pipes, typically has a male-threaded end which mates with female threads. The other end of the fitting has a single- or multi-barbed tube—a long tapered cone with ridges, which is inserted into a flexible hose. The nipple is a short stub of a pipe that has a male pipe thread at each end or at one end. The swage is like reducers but small in size and used to connect pipes to smaller screwed or socket welded pipes. Like reducers, they are also available in concentric & eccentric types.
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.
Union is a type of fitting, which functions as similar to coupling. But coupling cannot be removed after fixing but in this case we can remove the union whenever we needed. Although compression connections are less durable than soldered connections, they are easy to install with simple tools. However, they take longer to install than soldered joints and sometimes require re-tightening to stop slow leaks which may develop over time. Because of this possible leakage, they are generally restricted to accessible locations , and are prohibited in concealed locations such as the interiors of walls.
Install the valve following the established solvent procedure. A suitable support should be placed under the valve body to hold the weight of the valve. Be sure to adhere to proper curing times, and wipe off any excess cement that might have accumulated at the joint bead. The pressure losses and ow resistance in a line system are dependent on the internal diameter of the pipe, the ow velocity and the properties of the hydraulic oil .
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.
