RTJ Flange
The RTJ Flange offered by Hebei Yihang Steel Pipe Company Limited is a ring‑joint forged steel flange designed for high‑pressure and high‑temperature pipelines. It is produced from carbon steel, stainless steel or alloy steel conforming to ASTM A182 grades such as A105, A234WPB and Q235. Dimensions follow ASME B16.5 and API 6A, covering nominal pipe sizes from ½ in to 36 in and pressure classes 150, 300 and 600. The flanges feature a circular groove that accepts a metal‑to‑metal ring joint gasket.
The supplier can mill the flange from the three material families to meet customer‑specified corrosion or temperature requirements. Typical carbon‑steel RTJ flanges are supplied in mill‑condition with a black‑oxide coating for improved corrosion resistance, while stainless‑steel grades provide inherent resistance to aggressive media. The product complies with standard specifications ANSIB16.9, GB/T12459, DIN and JIS, ensuring dimensional tolerance of ±0.5 % on flange thickness. A black paint finish is available on request for additional anti‑corrosion protection.
These flanges are commonly installed in upstream oil‑field gathering lines, downstream refineries, petrochemical plants and power‑generation steam systems where a leak‑proof metal seal is mandatory. Hebei Yihang ships the items in wooden cases or according to buyer‑specified packaging, and can arrange FOB or CIF terms from the port of Tianjin. The company’s response rate is currently zero, so buyers should confirm lead time, minimum order quantity and payment conditions directly with the supplier before placing an order.

Sourcing RTJ Flange from Hebei Yihang Steel Pipe Company Limited - China Import Guide
Before placing an order, request the mill test report and material certification to confirm the ASTM A182 grade and compliance with ASME B16.5. Verify the flange dimensions, pressure class and bolt pattern against your engineering drawings. Ask for a sample or 3‑D model if custom dimensions are required.
Discuss the preferred incoterm with the supplier; common options are FOB Tianjin or CIF Shanghai. Because the supplier’s response rate is currently zero, obtain a confirmed lead time and shipping schedule in writing. Clarify payment terms, such as a letter of credit or advance payment, before finalising the contract.
Arrange an independent inspection at the factory or at the loading port to verify surface finish, coating condition and dimensional tolerances. Request a certificate of conformity and a packing list that details each case weight. Ensure that any anti‑corrosion paint applied matches the specification you have approved.
