Import Astm A53 Gr.B Equal Tee — Buy in Bulk from Supplier in China

The Astm A53 Gr.B Equal Tee is a butt-weld pipe fitting that splits a pipeline into two branches of identical diameter, manufactured to ASTM A53 Grade B carbon steel specifications. Zhengzhou Huitong Pipe Fittings produces this tee in seamless construction from 1/2 inch to 24 inch nominal pipe size, with welded construction available from 4 inch to 78 inch. Wall thickness options span Sch 5s through XXS, conforming to ASME B16.9 dimensional standards alongside JIS, DIN, EN and ISO equivalents. The Grade B designation specifies a minimum yield strength of 35,000 psi and tensile strength of 60,000 psi, with controlled chemistry for pressure piping service.

The fitting is forged or formed from carbon steel billet or plate, with full penetration butt-weld preparation for joining to Schedule-matched pipe. Surface condition is typically black (uncoated) or bare metal, though specific coating or lining must be confirmed with the supplier. End preparation follows ASME B16.9 for bevel angles and root face dimensions, ensuring proper weld profile and joint integrity. Heat treatment is typically normalised or stress-relieved for wall thicknesses above standard limits, though exact thermal processing for this stock should be requested. Material test reports (MTRs) referencing chemical composition and mechanical properties against ASTM A53 are standard documentation for pressure-rated fittings in this grade.

Buyers span petroleum refineries, chemical process plants, power generation facilities, gas distribution networks, metallurgical works, shipyards and commercial construction. The equal tee serves header connections, branch take-offs and flow splitting in steam, hydrocarbon, water and gas services within the temperature and pressure limits of ASTM A53 Grade B. For import procurement, confirm the specific size and schedule combination, whether seamless or welded construction is required, and request mill test certificates with Charpy impact values if specified for low-temperature service. Packaging is typically loose bulk or wooden pallet with steel strapping for ocean freight from Chinese port terminals.

Zhengzhou Huitong Pipe Fittings operates from Room 2004, Expo Center on Dongfeng Road in Zhengzhou, Henan Province, with the supplier classified at imported tier and harbour trust level. The company maintains a zero percent response rate with no recorded average response hours, indicating limited transactional visibility through this channel. Their listing covers a broad carbon and alloy pipe fittings portfolio, including elbows, tees, reducers, caps, crosses and weldolets across ASTM A234, A860, A420, A403, A815 and B366 material grades, plus stainless, duplex, nickel alloy and exotic grades.

The supplier's product range extends beyond carbon steel into specialised corrosion-resistant alloys including Monel, Inconel, Incoloy, Hastelloy and Nimonic. For buyers evaluating this source, the low response metrics suggest direct communication channels or third-party verification may be necessary before committing to order. The address places them in Zhengzhou's central business district rather than at a manufacturing site, so factory audit, production capacity and quality system certification status should be confirmed directly. No stated headcount, revenue figures, client references or certification scope is provided in the source data.
