HEBEI JINSHENG PIPE FITTING MANUFACTURING CO., LT

The company operates from Yanshan County, Cangzhou City in Hebei Province, China, and lists ten distinct pipe‑related products in its catalogue. The active product count of 10 includes buttweld carbon steel pipe elbows, buttweld seamless carbon steel equal tees, various carbon‑steel and alloy‑steel pipe bends, API 5L SSAW pipes, ASTM A252 SSAW steel pipe, carbon‑steel SSAW pipes, ASTM A106 Gr B seamless steel pipes, ASTM A333 seamless pipes, ASTM A53 seamless steel pipe, and carbon‑steel blind flanges. Each item is assigned to HS‑code families 7307.93, 7306.19, 7305.39, 7304.31, 7304.19 and 7307.19, matching the material declarations of carbon steel, stainless steel and alloy steel.

The catalogue notes compliance with major international standards such as ANSI/ASME B16.9/B16.5, API 5L, ASTM A106, A53, A333, A252, as well as EN/DIN, GOST, BS and JIS specifications. The supplier holds ISO 9001:2015, CE, GOST‑R and Pressure Equipment Directive (PED) certifications, indicating that its production lines meet recognised quality management and safety requirements. No other company‑specific data such as founding year or turnover are provided.

The listed products cover a typical range of butt‑weld and seamless pipe components used in oil‑and‑gas, petrochemical and water‑transport applications. In the industry, buttweld elbows and tees are commonly supplied in carbon‑steel grades such as ASTM A234 WPB (for low‑temperature service) and stainless grades like ASTM A403, with pressure classes ranging from 150 to 250 bar and diameters from DN 15 to DN 1200. API 5L SSAW pipes are usually produced to grades X42, X46, X52, X60, and X70, with wall thicknesses defined by the schedule system (e.g., Schedule 40/80). ASTM A106 Gr B seamless pipes are standard for high‑temperature service, while ASTM A333 covers low‑temperature seamless pipe (grades 6/6‑9). Blind flanges under HS 7307.19 are typically manufactured to EN 10253‑4 or ASME B16.5 dimensions, with pressure ratings up to 250 bar and bolt circle diameters matching the pipe schedule.

Industry practice also includes providing mill‑test reports, hydrostatic test certificates (usually 1.5 × design pressure), and surface‑treatment specifications such as NACE MR0175 for corrosive environments. Buyers often request dimensional drawings, schedule numbers, and material certificates for each size and grade, enabling direct integration into engineering specifications.
