3×20 Inch ASTM A105 Stainless Steel Weldolet Pipe Fittings SCH 80 MSS-SP-97

ASTM A105 Weldolet, 3×20 Inch, Wall Thickness SCH 80, Standard MSS-SP-97, Butt Weld Ends

Branch platform is also called branch seat, saddle, saddle type pipe joint. It is mainly used for reinforcing pipe fittings of branch pipe connection, instead of using different diameter three-way, reinforcing plate, strengthening pipe section and other branch pipe connection types. It has the advantages of safety and reliability, cost reduction, simple construction, improvement of medium flow channel, series standardization, convenient design and selection, especially in high pressure, high temperature, large caliber, thick wall pipeline, which is increasingly widely used, replacing the traditional branch pipe connection method.

Common specifications
The branch pipe table body adopts high quality forgings, the material is the same as the pipe material, there are carbon steel, alloy steel, stainless steel and so on. The branch seat and the supervisor are welded, and the connection with the branch pipe or other pipe (such as short pipe, wire plug, etc.), instrument, valve has three types of butt welding connection, socket welding connection, thread connection. Branch platform commonly used manufacturing execution standards such as MSS SP-97,GB/T19326 standards.
Characteristics
The branch pipe platform has the advantages of safety and reliability, cost reduction, simple construction, improvement of medium flow channel, standardization of serialization and convenient design and selection, especially in high pressure, high temperature, large caliber and thick wall pipes, which is increasingly widely used, replacing the traditional branch pipe connection method.
Composition technology
1. welding branch pipe table is generally made of integral forgings. The structure of branch pipe table is divided into main connection end, strengthening part and branch pipe connection end.
Evaluation of welding technology of 2. branch pipe table
V groove of the weld of the branch pipe table is a single side groove, which can be determined as the combination weld of butt weld (groove weld) and fillet weld.
welder qualification requirements for 3. pipe stand
Welders shall obtain relevant welding procedures in accordance with the relevant provisions of the Detailed Rules for the Examination of Welding Operators of Special Equipment
Project qualification, considering the pipe outer diameter cover, should consider the branch pipe table groove surface diameter (branch pipe outer diameter), the supervisor diameter is not within the welder evaluation consideration range. When there is a transition slope, the diameter of the groove surface refers to the actual diameter measured from the groove surface, which is generally smaller than the outer diameter of the branch pipe table, while the pipe table is welded as a combination weld of butt weld and fillet weld with groove in the branch pipe. As a result, welder holding 6 G pipe certificate can be covered.
