It develops, manufactures and markets RTP, which is a flexible high pressure pipe. It is supplied in long length coils of up to 400m length and has design pressure ratings from 36 to 450 bar. This type of pipe is typically used in the oil and gas industry for oil and gas flowlines, high pressure water injection and water transportation lines.
HDPE pipe is a type of flexible plastic pipe used to transfer fluids and gases. It is often employed for replacing aging concrete or steel main pipelines . Constructed from the thermoplastic HDPE (high-density polyethylene ), it has low permeability and robust molecular bonding, making it suitable for high-pressure pipelines .
[21]: 147, 149 A flexible fitting may be preferred to connect a shower or heavy tub to the drainage system without transmitting slight movements or stresses, which could eventually cause cracking. [21]: 159 Flexible fittings may also be used to reduce the transmission of vibration into the DWV system.
The gasket sealing is enhanced as the coupling housing is tightened onto the pipe end. "The economics of the grooved method derive from simplified assembly that involves three basic concepts: a pressure responsive gasket that creates a leak-tight seal; couplings that hold the pipe together; and fasteners that secure the couplings.

The company specialized in gas main installations, putting in the original gas mains in Rhode Island. They eventually grew to offer pipe fitting and plumbing services. In 1869, Frederick Grinnell, a Massachusetts-born engineer, purchased a controlling interest in Providence Steam and Gas and became its president. Fire protection was a new ...
Alternatively it is a short length of pipe with two female National pipe threads (NPT) (in North American terms, a coupler is a double female while a nipple is double male) or two male or female British standard pipe threads. If the two ends of a coupling are of different standards or joining methods, the coupling is called an adapter. Examples ...
For hoses and piping, a quick connect fitting, also called a push fitting, is a coupling used to provide a fast, make-or-break connection of gas or liquid transfer lines. Operated by hand, quick connect fittings replace threaded or flanged connections, which require wrenches. When equipped with self-sealing valves, quick connect fittings will ...
Copper pipe fittings. Fittings are also used to split or join a number of pipes together, and for other purposes. A broad variety of standardized pipe fittings are available; they are generally broken down into either a tee, an elbow, a branch, a reducer/enlarger, or a wye. Valves control fluid flow and regulate pressure.
