Common Queries
Technical Frequently Asked
What is your typical lead time for custom LSAW pipe orders?
Normally, for standard custom orders, our lead time ranges from 15 to 30 days depending on the raw material availability and specific coating requirements. Large-scale infrastructure volumes might vary.
Do you provide Third-Party Inspection (TPI) services?
Yes, we offer full cooperation with world-renowned inspection agencies such as SGS, BV, Lloyd's Register, and DNV. We welcome TPI audits at any stage of our production process.
Can you produce pipes according to unique international drawings?
Absolutely. We specialize in OEM/ODM manufacturing. Our engineering team can analyze your specific drawings and ensure all tolerances, dimensions, and material compositions meet your unique project requirements.
What are your minimum order quantities (MOQ)?
For stock items, there is no strict MOQ. For custom manufacturing, MOQ typically starts from 5–10 tons depending on the specific pipe diameter and specialized coating requirements.
How do you ensure sea-worthy packing for international exports?
We use heavy-duty steel strapping, protective plastic end caps, and corrosion-resistant wrapping for all export items. Specialized crating or bulk-packing is also available for ultra-large diameter pipes.
