Liaocheng Luzhen Metal Manufacturing Co., Ltd.

Liaocheng Development District Luzhen Metal Manufacturing Co., Ltd. Located in Liaocheng, the beautiful City North of the Yangtze River, the city is traversed by the Beijing‑Hangzhou Grand Canal, Beijing‑Kowloon Railway and Jinan‑Liaocheng Expressway, enjoying highly convenient transportation. It is a large seamless steel pipe manufacturer integrating production, sales and logistics. In 2009, the company introduced 6 sets of precision rolling mills and established Shandong Precision Steel Pipe Factory. It can produce high‑precision cold‑rolled tubes and precision bright tubes with dimensions Φ4‑114 mm × wall thickness 0.4‑25 mm. The dimensional tolerance can reach 0.025 mm, and the surface roughness can be 1.6, 0.8 or 0.2. Besides, we can customize various special‑shaped steel pipes according to customer requirements, including square tubes, elliptical tubes, hexagonal tubes, outer‑round inner‑elliptical tubes, outer‑flat inner‑round tubes and other profiled steel pipes. In 2010, the company put into operation a longitudinal submerged‑arc welded (LSAW) pipe production line for large‑diameter longitudinal welded pipes, with an outer diameter range of Φ350‑1420 mm, wall thickness 6‑80 mm and length 6‑12 m. In compliance with API 5L specifications, we can supply LSAW pipes for oil and gas transmission with outer diameter Φ350‑1420 mm, wall thickness 6‑40 mm, length 6‑12 m and steel grade up to X70. Equipped with a heavy plate bending unit, we fabricate welded pipes with outer diameter Φ1400‑5000 mm, wall thickness 12‑100 mm and single‑piece length 3500 mm. We are also capable of manufacturing seamless steel pipes of Φ820 mm OD × 60 mm wall thickness. Our factory owns 5 seamless pipe piercing production lines, 6 cold‑drawing lines, 6 hot‑rolling lines and 2 hot‑expanding lines. As a well‑known enterprise among Shandong seamless steel pipe manufacturers, we produce seamless pipes with outer diameter 10‑377 mm and wall thickness 1‑80 mm. Custom non‑standard pipes can be hot‑expanded within OD 219‑1020 mm and wall thickness 6‑60 mm upon clients’ requests. Our products are widely used in engineering, coal mining, textile, electric power, boiler, machinery, military industry and other industrial sectors. We operate six large‑scale warehouses for seamless steel pipes covering an area of 170 mu: ‑ 3 carbon steel seamless pipe warehouses stocked with grades 20#, 45# ‑ 1 low‑alloy pipe warehouse stocked with 16Mn, 40Cr, 27SiMn ‑ 1 high‑pressure alloy pipe warehouse stocked with 12Cr1MoV, 15CrMo, 12Cr1MoVG, 15CrMoG, P22, T22 (10Cr1Mo910), P91, T91, Cr5Mo, Cr9Mo, 12Cr2MoWVTiB ‑ 1 stainless steel pipe warehouse stocked with 201, 202, 301, 302, 304, 304L, 321, 316L, 310S With a complete range of sizes and material grades, we truly provide one‑stop procurement service for seamless steel pipes. We have established long‑term business partnerships with major steel mills including Baotou Seamless Steel Pipe Plant, Chengdu Iron & Steel, Tianjin Iron & Steel Group, Hubei Xinye, Shanghai Baosteel, Guangzhou Liuzhong, Great Wall Special Steel, Hsin Hua Li‑Hua, Jiuli Special Material, Shanxi Taigang and Wenzhou Baofeng. We supply a full portfolio covering Φ4‑1220 mm × wall thickness 1‑120 mm: seamless steel pipes, large‑diameter seamless pipes, stainless steel pipes, stainless steel sheets, stainless steel bars, stainless steel square & rectangular tubes, steel plates, fluid‑transport pipes, high‑/medium‑/low‑pressure boiler tubes, petroleum cracking tubes, special pipes for chemical fertilizers, marine pipes as well as domestic and imported alloy steel pipes.
