ANSI B165 ASTM A105 A106 Stainless Steel Flanges 304 316L Lined Flange
ANSI B165 ASTM A105 A106 304 316L Stainless steel lined flange
Description
Stainless steel lined flange, also known as composite flange and lining ring flange, is to weld stainless steel or lining a layer of stainless steel plate on the outside of stainless steel flange (mainly sealing surface and inner diameter). It is a flange without hole in the middle, which is used to seal the pipe plug. The function is the same as that of welded head and threaded pipe cap.

Characteristic
Stainless steel lined flange is similar to that of looper flange. It is made of materials consistent with the medium contact surface and embedded or welded on the pipeline, which can not only meet the expected effect of customers in the use project, but also greatly reduce the cost investment.
Application
Stainless steel lined flange is mainly used in boiler and pressure vessel, petroleum, chemical industry, shipbuilding, pharmacy, metallurgy, machinery, food and other industries.
