What do you know about blind boards?
The formal name of blind plate is flange cap, some also called blind flange or pipe plug. It is a flange without a hole in the middle, used to seal the pipe mouth. The FUNCTION IS THE same AS the head and the tube cap, except that the blind seal is a deTAChable sealing device, and the head seal i...Read more -
Polishing methods for biphasic steel flanges
1. There are four polishing methods of bi-phase steel flange: manual, mechanical, chemical and electrochemical. The corrosion resistance and decoration of the flange can be improved by polishing. The existing electric polishing fluid of stainless steel still uses phosphoric acid and chromic anhyd...Read more -
What should be prepared before measuring large diameter flange

How to dehydrogen annealing forgings
Post-forging heat treatment of large forgings after forging forming, immediately after the heat treatment is called post-forging heat treatment. The purpose of post-forging heat treatment of large forgings is mainly to de-stress, recrystallize grain refining and dehydrogenation at the same time. ...Read more -
What are the advantages and disadvantages of free forging classification?
One. Introduction to free forging Free forging is a forging method that makes the metal between the upper and lower anvil iron produce plastic deformation under the action of impact force or pressure, so as to obtain the desired shape, size and internal quality forgings. Free forging in free forg...Read more
