Top Quality Pipe End Fittings - Axially Restrained With Double Anchor Rings Coupling – Grip

Technical Parameter: 【VIEW】

PRODUCT DETAILS

The GRIP-G coupling is designed to replace the need for flanging, welding, pipe grooving and pipe threading by providing a quick and easy solution to joining plain-end pipe. The GRIP-G has two anchor rings which are placed adjacent to, but separate from, the sealing mechanism.

Suitable for pipes sizes from O.D φ26.9 to-φ273mm.

Suitable for pipes material: Carbon steel, stainless steel, copper, cunifer, cast and ductile iron, GRP, most plastic and other material.

GRIP-G Axially restrained with double anchor rings coupling is the most popular type in GRIP Coupling series. Two anchor rings have progressive anchoring effect, it is easy on pipes, as pressure increased, so does the gripping effect. GRIP-G offers high levels of security by locking pipes together under pressure. GRIP-G working pressure up to 46 bar. Temperature range: -30℃ up to 180℃, material in SS304, SS316 and SS316TI. It suitable for most applications in shipbuilding, offshore industries, water and waste treatment, industrial process pipe work and others.
