Panyu Chu Kong Steel Pipe (Lianyungang) Co., Ltd.

What Panyu Chu Kong Steel Pipe (Lianyungang) Co., Ltd. does

Panyu Chu Kong Steel Pipe (Lianyungang) Co., Ltd. is a subsidiary within Chu Kong Petroleum and Natural Gas Steel Pipe Holdings Limited (珠江石油天然气钢管控股有限公司), a Hong Kong-listed (HKEX: 01938.HK) steel pipe manufacturer founded in 1993. The company designs and manufactures large-diameter welded steel pipes for offshore and onshore oil and gas transmission, serving energy majors (TotalEnergies, Saudi Aramco, Shell, Chevron), national oil companies (CNOOC, Sinopec (中国石油化工集团有限公司), CNPC (中国石油天然气集团有限公司), NNPC, Kuwait Oil Company), EPC contractors (Daewoo), and infrastructure projects (Hong Kong-Zhuhai-Macao Bridge, Shenzhen-Zhongshan Bridge, Dangote Refinery). Operations span 80+ countries across Asia, Africa, Europe, the Middle East, Oceania, and the Americas via three manufacturing bases in Guangzhou Panyu, Zhuhai Jinwan, and Lianyungang Xuwei New District, the latter two of which feature coastline-adjacent loading infrastructure.

The core technology stack includes JCOE and COE submerged arc welding (SAWL), spiral submerged arc welding (SAWH), high-frequency welding (HFW), multi-phase microstructure alloying regulation, advanced non-destructive testing, and in-house coating capabilities (3LPE, FBE, cement weight coating). The company's flagship technical achievement is the world's first successful trial production of 3500-meter ultra-deep subsea oil and gas welded steel pipe (2023), enabling deployment at near 0°C temperatures and 350 atmospheres pressure and breaking a previously Western-dominated bottleneck. Manufacturing produces pipes from 4" to 92" diameter qualified to API 5L PSL1/PSL2, DNV-OS-F101, ASTM A671, and API 2B. The company holds 8 patents and participated in establishing 4 national standards for ultra-deep seabed pipeline technology.

Revenue is generated through project-based, one-time enterprise contracts secured via direct technical qualification and negotiation with energy majors and NOCs; pricing is contract-specific and varies by pipe specification, coating requirements, and order volume. The sales motion is enterprise field sales targeting mega-infrastructure projects such as the 1,443 km TotalEnergies EACOP heated crude oil pipeline (260,000 MT contract) and the Saudi Aramco Marjan Increment program. 2024 revenue reached RMB 29.4 billion (+10.9% YoY) with overseas sales of RMB 22.19 billion (+61.9% YoY); 2025 H1 revenue was ~RMB 13.89 billion (+32.6% YoY). Distribution is direct factory-to-site via self-operated 5000DWT berths and 300mt gantry cranes at the Lianyungang base plus a coastline-adjacent Zhuhai facility, supporting chartered ocean-vessel shipments to project ports worldwide.
