The seamless steel boiler tube from Ez Steel Pipe conforms to ASTM A106 Grade B carbon steel, a standard for high‑temperature pressure service. It is supplied as a seamless pipe, eliminating weld seams that could become leak points under steam and water pressure. Typical dimensions include outer diameters from 21 mm up to 219 mm and wall thicknesses that follow standard schedule numbers such as SCH 10 to SCH 40. The material provides a minimum tensile strength of 415 MPa and a yield strength of 240 MPa at ambient temperature, as required by the ASTM specification.
In the boiler‑tube market, standard tolerances are ±0.3 mm for diameter and ±0.2 mm for wall thickness, and the surface finish is usually a cold‑drawn, smooth finish. Typical testing includes a hydrostatic pressure test at 1.5 times the design pressure and a chemical analysis to verify carbon, manganese and sulfur limits. Buyers often request a mill test certificate that details the chemical composition and mechanical properties according to ASTM A106. The tubes are commonly shipped in bundled packs or wooden crates, with lengths up to 12 m per piece.
These boiler tubes serve power‑generation plants, refineries and industrial heating systems where reliable heat exchange is critical. Importers such as EPC contractors, plant engineers and equipment distributors usually order them in large quantities to meet project schedules. Trade terms, packaging options and delivery lead times should be clarified with Ez Steel Pipe before finalising the purchase.

Sourcing Seamless Steel Tube Boiler Tube (ASTM A106) from Ez Steel Pipe - China Import Guide
Before ordering, confirm that the pipe grade, outer‑diameter range and wall‑thickness schedule correspond to your boiler design specifications. Ask Ez Steel Pipe to supply the mill test certificate and any chemical analysis reports to verify compliance with ASTM A106 requirements.
Agree on the Incoterm - usually FOB or CIF from the port of Changsha - and confirm payment terms such as a confirmed letter of credit. Typical lead times for ASTM A106 boiler tubes are five to eight weeks after order confirmation, but the exact schedule should be verified with the supplier. Ensure that the packaging method, whether bundled or crated, meets your handling and storage constraints.
Arrange for a third‑party inspection to check dimensions, wall‑thickness tolerance and surface finish before shipment. Non‑destructive testing, such as ultrasonic examination, can identify internal defects that could affect pressure performance. Request all export documentation, including commercial invoice, packing list and certificate of origin, to streamline customs clearance in the destination country.
