Import Boiler Tube — Buy in wholesale FOB from Supplier in China

Liaocheng Xinruyi Trading Co,. Ltd. supplies boiler tubes sourced from manufacturing bases with production experience dating from 2006, offering seamless tubes across a broad dimensional envelope. The available size range covers outer diameters from 21.3 mm to 508 mm with wall thickness from 3 mm to 50 mm, suitable for both general boiler service and high-pressure applications. The supplier references compliance with multiple national and international standards including DIN 17175, EN 10216, ASME SA-106M, SA-192M, SA-209M, SA-210M, SA-213M, SA-335M, GB 3087, GB 5310, and JIS G3456, G3461, G3462. This breadth of standards coverage allows supply against project specifications originating from European, American, Chinese, and Japanese boiler design codes.

The material distinction between general boiler tubes and high-pressure boiler tubes is central to correct specification. General boiler tubes, operating below 5.88 MPa and under 450 degrees C, typically use carbon steels 10# and 20#. High-pressure service demands alloy grades such as 20G, 20MnG, 25MnG, 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, and 12Cr3MoVSiTiB, which resist creep and thermal fatigue at working pressures above 9.8 MPa and temperatures between 450 degrees C and 650 degrees C. The supplier notes that high-pressure tubes command higher pricing due to alloy content, tighter metallurgical control, and more extensive testing requirements. Heat treatment is applied to eliminate stress concentrations introduced during forming, with normalising and tempering standard for alloy grades.

These tubes find application across power generation, petrochemical processing, and industrial heating systems. Buyers include EPC contractors for coal-fired and combined-cycle power plants, refinery maintenance teams replacing heater tube bundles, and boiler OEMs building new units.
