Import Alloy Seamless Steel Tube — Buy in Bulk from Supplier in China

The alloy seamless steel tube from Yangzhou Lontrin Steel Tube Co., Ltd. is manufactured to API 5CT standards, ensuring compliance with rigorous oil and gas industry requirements. The seamless construction eliminates weld seams, providing uniform strength and resistance to high-pressure environments. This tube is designed for applications where structural integrity under extreme conditions is non-negotiable, such as in petroleum extraction, refinery pipelines, and high-temperature boiler systems.

Material composition typically includes carbon-manganese or low-alloy steel grades conforming to API 5CT specifications, with common variants such as J55, K55, N80, L80, and P110. Surface finishes include bare or coated options, with coated variants offering enhanced corrosion resistance in aggressive media. Standard outer diameters range from 10.3 mm to 114.3 mm, with wall thicknesses between 2.1 mm and 12.7 mm typical for these grades, though exact dimensions depend on the buyer’s project specifications.

Primary buyers include oil and gas contractors, drilling companies, and industrial plant operators sourcing for upstream and midstream infrastructure. The tube is supplied in random lengths or fixed lengths as requested, with ends plain, beveled, or threaded. Logistics typically involve bundling with steel strips and protective end caps, with FOB or CIF terms negotiable. Buyers should confirm lead times and packaging standards, as these are not specified in the listing.
