MSS-SP-97 BUTT WELDED PIPE STAND ASTM A105 CARBON STEEL 3000LB 3"×4"

The support platform is also called the support seat, saddle seat, and saddle type pipe joint. It is mainly used for reinforcing pipe fittings of branch pipe connection, instead of using reducing tee, reinforcing plate, reinforcing pipe section and other branch pipe connection types. It has the advantages of safety and reliability, reducing cost, simple construction, improving medium flow channel, series standardization, convenient design and selection, etc., especially in high pressure, high temperature, large diameter, thick wall pipes are used increasingly widely, replacing the traditional branch pipe connection method.

The body of the branch pipe is made of high-quality forgings, and the material is the same as that of the pipe, including carbon steel, alloy steel, stainless steel, etc. The branch pipe base and the main pipe are welded, and the connection with the branch pipe or other pipes (such as short pipe, wire plug, etc.), instruments, valves has three types of butt welding connection, socket welding connection, and thread connection. The common manufacturing execution standards of the branch pipe are MSS SP-97, GB/T19326 and other standards.

The branch pipe table has the advantages of safety and reliability, reducing cost, simple construction, improving the medium flow path, serialization and standardization, convenient design and selection, etc., especially in the high pressure, high temperature, large diameter, thick wall pipeline is increasingly widely used, replacing the traditional branch pipe connection method

A105 is ASTM Standard number, A stands for ordinary carbon structural steel.

Ingredients C: 0.35 or less Si: 0.35 Mn or less: 0.6 1.05 S: 0.050 or less P: 0.040 or less, Cu Ni acuities were 0.4 0.4 or less Mo 0.12 V 0.08 or less or less Cr 0.3 or less

Mechanical properties between 20 forged steel and 16Mn forged steel.

Mechanical Properties (Mpa)

Tensile strength :(σb)≥485Mpa

Yield strength (σs)≥250Mpa

Rear elongation (δ)≥22%

Section shrinkage (ψ)≥30%

Hardness ≤HB187

Note: In the pipeline system, A105 can generally replace No. 20, but No. 20 can not completely replace A105, because the strength difference is still large. However, the resistance to stress corrosion cracking (SCC) of the A105 is slightly worse than that of the 20.

Butt welding branch pipe table is a kind of branch pipe table which is widely used in foreign countries in recent years. It is a reinforced pipe fitting for branch pipe connection. Instead of the traditional branch pipe connection types such as reducing tee, reinforcing plate and strengthening pipe section, it has the outstanding advantages of safety and reliability, reducing cost, simple construction, improving medium flow path, series standardization and convenient design selection. Especially in high pressure, high temperature, large diameter, thick wall pipe used increasingly widely, replacing the traditional branch pipe connection method.

The body of the branch pipe is made of high-quality forgings, and the material is the same as that of the pipe, including carbon steel, alloy steel, stainless steel, etc. The branch pipe and main pipe are welded, and the branch pipe table and branch pipe or other pipes (such as short pipe, wire plug, etc.), instruments, valves are connected by butt welding, socket welding, thread and other types.
