Sanvo can provide various thread pipe couplings according to the needs of every valuable hardware customers. Sanvo Pipes & Fittings is a trustworthy and reliable supplier who specializes in producing the highest quality pipe couplings with strict management control on producing process of pipe cutting, threading, bending, end finishing, grooving and more.

A Pipe coupling ( or socket)  is a shorter segment of seamless pipe with female threading at each end, and pipe socket is typically used to connect two other pipes, fittings, or hoses.

Pipe couplings ( or sockets)  are usually made from carbon and stainless steel, and always seamless. Pipe couplings ( or sockets) are used in many industries, such as Water & plumbing, Gas & Petro Chem, Hydraulic, Pumping, Agriculture and more.

The use of socket pipe fitting makes it easier to adjust the position of tubes to fit your exact specifications. There are also many variefies of couplings; the main ones being rigid, merchant, straight, and tapered.

Adhering to Sanvo's consistent business objectives "quality first, price concessions, timely delivery, thoughtful service", we pride ourselves on providing pipe couplings with excellent quality and OEM service for our valuable hardware customers.

Our pipe couplings are available in the following size: 1/8 ", 1/4 ",3/8 ", 1/2 ", 3/4 ", 1 ", 1-1/4", 1-1/2 ", 2 ", 2-1/2 ", 3 ", 4 ",5", 6 ". Or you can contact us for more information with your specific needs on pipe couplings and nipples, by sending e-mail to info@pipenipples.com or use our easy online Request for Quote Form. Our pipe professionals are available to help you answer any questions.

Product description

Stainless steel socket weld flange is a flange with one end welded with steel tube and the other end connected with bolts. It is suitable for connecting pipe with small diameter, high pressure and high temperature, usually used in the pipelines with PN≤ 10.0mpa and DN≤40.

Socket weld flanges are counter-bored to receive the pipe earlier than being fillet welded. The bore of the pipe and flange are both the equal to grant exact float characteristics. Stainless steel socket weld flanges are oxidation resistant and promote better weldability and fabricability. WENZHOU HUASHANG STEEL CO.,LTD is one of the most professional   socket weld flange manufacturers   in China.

WHAT'S THE DIFFERENCE AMONG WELD NECK FLANGES, SOCKET WELD FLANGES, SLIP ON FLANGES?

Weld neck flanges, slip on flanges, socket weld flanges have different production standards, different applicable occasions. In addition, weld neck flange is the interface end pipe diameter and wall thickness is the same as the pipe to be welded.

Slip on flange is the joint being processed to a concave table a little larger than the pipe outside diameter, pipe inserted in the inside for welding. Weld neck flange has better welding performance and less corrosion.

Slip on flanges are generally used for low and medium pressure pipelines, weld neck flanges are used for connection of middle and high pressure pipelines, generally at least pn2.5mpa. Weld neck flanges are used to reduce stress concentration.

Features of various forged flanges:

Socket welding flange is suitable for connecting pipe with small diameter, high pressure and high temperature.

Slip on flange is the same with weld neck flange, has a groove cut in the lug and the pipe inserted into it for welding.

Socket weld flange has no boss, directly cut a groove in the flange body, just like a hole in the blind flange, and then cut a groove.

Slip on flange is slightly better than socket weld flange in performance.
