Flanges
Hebei Sailin Trade Co., Ltd. supplies carbon steel and stainless steel flanges manufactured to ANSI and DIN standards, with nominal sizes from DN15 to DN600. These components are produced via forging or plate machining processes and comply with ASTM A105, ASME B16.5, and ISO 7005-1. The flanges are designed for high-pressure and high-temperature environments in oil and gas pipelines, chemical plants, and water treatment infrastructure.
Material options include ASTM A105 carbon steel and 304/316 stainless steel, with surface finishes typically ranging from mill finish to anti-corrosion coatings. Standard pressure classes cover 150, 300, 600, and 900 lb, with typical tolerances for face-to-face dimensions within ±1.5 mm and bolt hole alignment within ±0.5 mm. These are standard industry parameters for forged flanges, not guaranteed unless confirmed by the supplier.
End users include engineering contractors, EPC firms, and industrial maintenance teams across Southeast Asia, the Middle East, and Africa. Packaging is typically in wooden crates or steel strapping for sea freight, with export documentation including commercial invoices and packing lists. Trade terms are commonly FOB Tianjin or CIF destination port. MOQ and lead time vary by size and grade and must be confirmed directly with the supplier.

Sourcing Flanges from Hebei Sailin Trade Co., Ltd. - China Import Guide
Before ordering, verify the material grade and compliance standard with a certified material test report. Confirm that the flange dimensions match your piping system’s ANSI or DIN specification, especially bore diameter, bolt hole count, and face type. Request a sample for fit-check if this is your first purchase from the supplier.
Confirm Incoterms such as FOB Tianjin or CIF destination, and whether the supplier handles export documentation. Lead time typically ranges from 25 to 45 days for standard sizes, but custom orders may take longer. Payment terms are commonly 30% advance with balance against BL copy. Clarify if container loading and port charges are included.
Inspect flanges upon arrival for surface defects, correct marking, and packaging integrity. Verify that each batch includes a material certificate with heat number and test results. Use a caliper to check critical dimensions and a magnet test to distinguish between carbon and stainless steel. Retain samples for third-party lab testing if used in critical systems.
