Flat welding flange manufacturers bring you to understand the flange corrosion problems
Flat welding flange manufacturers bring you to understand the flange corrosion problems The direct external cause of flange and bolt corrosion is the existence of corrosive medium between the flange clearance, in the absence of anti-corrosion coating protection, flange metal surface and bolt dire...Read more -
Cause analysis of leakage of neck flange
Cause analysis of leakage of neck flange The neck flange will inevitably leak in the use process. The common reasons for leakage are as follows: 1, the wrong mouth, the wrong mouth is straight pipe and flange, but the two flanges are different so that the bolts around can not easily enter the bol...Read more -
Three important parameters in flange standards
1. Nominal diameter DN: Flange nominal diameter refers to the nominal diameter of the container or pipe with the 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 -
