Credibility ,Stainless steel and carbon steel composite flange production generally have two ways: one is the use of explosive or rolling method will be made of stainless steel plate and carbon steel composite plate, and then made into a flange.
Stainless steel flanges made of this method are good. However, the requirements of the composite technology, composite equipment and personnel are very high, the general production of manufacturers can not do, and the cost is higher; two is on the carbon steel flange sealing surface, welding on stainless steel plate, and then in the lathe Colonel level. This method makes the composite flange use effect is not good, but the technology, equipment and personnel requirements is not high, the general factory can do, and can use the stainless steel plate of the side of the waste, the cost is lower. I plant in 1993 began to use this method to produce stainless steel flange / carbon steel composite flange. Its production method is as follows: to prepare a piece of rough or carbon steel flange without a car sealing surface as a base material.
With 4 ~ 6mm stainless steel plate splicing flange sealing surface, outer diameter and the outer diameter of the original flange sealing surface, a small diameter of 2 ~ 3mm, easy to weld flange and pipe.Tel No:+86-18267732328 / Email:[email protected]
