Frequently Asked Questions
What are the primary applications for 16Mn alloy steel seamless pipes?
They are mainly used for manufacturing water wall pipes, boiling water pipes, superheated steam pipes for boilers, and locomotive smoke pipes.
What is the temperature resistance of these pipes?
These pipes are designed to be low-temperature resistant, maintaining performance at temperatures as low as ≤-40ºC.
Can the wall thickness be customized?
Yes, while our standard thin-walled range is 2-10mm, we can provide wall thicknesses from 1mm up to 200mm based on specific requirements.
Which international standards do your pipes comply with?
Our products comply with various global standards including API 5L, ASTM A106, ASTM A53, DIN 17121, and EN 10305-1.
What surface treatments are available?
Standard pipes come with a black surface treatment. We also offer further processing like surface shot blasting and laser marking.
How are the pipes packaged for international shipping?
We use standard seaworthy packaging, typically in bundles secured by steel strips to ensure safety during transport.
