Concave-convex Flange Product
The production of flange should undergo a chain of processing, together with casting clean, difficult cutting, best turning, dull, drilling, warmth treatment, nice inspection, and many others. we are able to system the flange at distinct tiers according to the requirements of customers. and there are API 20b , API q1 certificates identified by using American petroleum institute, and the quality has passed ISO9001. product great and after-sales may be guaranteed. Our gain in flange production is that seamless ring rolling technique is followed, that could shop fee and can be processed in batches.
Flange is a common mechanical connector, which is used to connect two or more parts together and provide a stable connection. It is usually made of round metal or plastic and has some fixed holes for the perforation of bolts or screws.
