Frequently Asked Questions (FAQ)
What are the primary applications for alloy steel pipes?
Alloy steel pipes are primarily used for pipeline transport, boiler systems, power plants, and high-pressure services where high-temperature resistance is required.
What is the difference between ASTM A106 and A335?
ASTM A106 is a specification for carbon steel pipes used in high-temperature service, whereas ASTM A335 specifically covers seamless ferritic alloy-steel pipes for similar high-temperature applications.
Do you provide surface treatments for the pipes?
Yes, our pipes typically come with varnishing or oil coating (black/oil) to prevent corrosion during transport and storage.
How are the pipe ends finished?
Standard products are supplied with Plain Ends (PE), though other configurations can be discussed based on specification requirements.
What standards do your pipes comply with?
Our pipes are manufactured according to international standards including ANSI B36.10, and material specifications such as ASTM A335, A106, A333, and A312.
How are the pipes protected during shipping?
We protect the pipes with end caps and ensure they are packaged securely for bulk transport to prevent damage to the surface and ends.
