Socket welding flange(SW flange) refers to the flange which is welded at the end and outside of the pipe by inserting the end of the pipe into the step of the flange ring.There are neck and no neck.The flange with neck has good rigidity, small welding deformation and good sealing property.It can ...

There are the problems we should pay attention to when processing butt welded flange: 1.Annealing air. The pure hydrogen is generally used as annealing air for butt welding flange. The air purity is over 99.99%. If the other part of the air is inert gas, the purity can also be lower, but it can ...

Stainless steel flange will not produce corrosion,pitting corrosion,rust,easy to wear.Stainless steel(SS) is one of the most intensive building metal materials.Because stainless steel has good corrosion resistance,it can make structural parts permanent to maintain the integrity of Engineering de ...

In the process of using large size forged flange,leakage occurs due to improper connection of large flange or long service life.Users need not worry about this situation.First,look at the leakage site.In general,it is impossible to eliminate the leakage by injecting sealant into the gap due to t ...

The metal flange should be greased before storage for a long time, and the storage space should be dry to prevent rust.Each flange should be stored separately.Because of the different materials and batches of metal materials, contact storage will accelerate corrosion and rust due to electrochemi ...

A few days ago,a customer asked me to send sample of slip on ring lap joint flange.He wanted to order some products for his construction project.I sent samples of these products to him and also found some documents regarding the products. Slip on ring lap joint flange is movable flange and direc ...

Blind flange(abbreviation is BL),its proper name is flange cover.It is a flange without holes in the middle for sealing the pipe plug.There are many types of sealing surface,such as flat face,raised face,ring joint face,tenon and groove surface,and ring connection surface. ANSI B16.5 A105 forged ...

Forged flange is a flange in mechanical performance is one of the best products,its raw material is commonly tube billet,and then after cutting to constantly pounding,to eliminate the segregation of steel ingot defects,osteoporosis, etc.Price and mechanical properties are higher than normal cast ...

Flange production process is divided into forging and casting. Forged flange is generally lower in carbon content than cast flange,less easy to rust,better streamlined forging,compact structure and better mechanical properties than cast flange.Improper flange forging process will also lead to la ...

Flanges can be divided into five basic types according to their connection with pipes:flat welded flange,butt welded flange,threaded flange,socket welded flange and loose flange.There are many types of flange sealing surface,such as protruding surface (RF),concave surface (FM),convex surface (M) ...

The two parts of the spectacle blind flange could be separated to be used,the blind part of the spectacle flange is called spade or paddle,it is used to block the flow fluid in the piping system.The opening part of spectacle flange is called spacer or ring spacer,when it is worked in the two fla ...

Spectacle blind flange also called figure-8 blind flange.The “8” character blind plate is named for its shape,similar like an 8-character.It is used to isolate or connect piping systems. The “8” blind flange is a steel plate with fixed thickness divided into two plates.Tw ...
