Hebei Dingli Pipe Industry Co., Ltd., established in 2003 and located in Jing County, Hebei Province – the hometown of the renowned Confucian scholar Dong Zhongshu, has emerged as a leading manufacturer in China’s petroleum equipment industry. Specializing in the production of high-strength hydraulic hose assemblies and petroleum machinery parts, the company serves as a crucial manufacturing base for fire-resistant hoses for China National Petroleum Corporation’s well control equipment manufacturing center.

Technical Excellence in Steel Wire Braided Layer Production
The company’s core strength lies in its advanced manufacturing capabilities for steel wire braided layers, which form the critical reinforcement structure in high-pressure hydraulic hoses. With 12 professional engineers and a team of 50 skilled workers, Dingli Pipe Industry maintains strict quality control throughout the production process. Our state-of-the-art facilities include multimedia computer-controlled high-pressure impact testing equipment and comprehensive rubber material analysis systems, ensuring each steel wire braided layer meets exacting standards.
As a specialized steel wire braided layer supplier, we employ advanced braiding technology that enables precise control over wire angles, tensions, and layer counts. This technical precision allows us to produce hoses with working pressures ranging from 10,000 psi to 15,000 psi (70 MPa to 105 MPa), suitable for the most demanding oilfield applications. Our proprietary braiding patterns have been developed through years of field testing and collaboration with major oil companies.
Comprehensive Processing Services for Industrial Applications
Beyond standard production, Hebei Dingli offers specialized steel wire braided layer processing services tailored to customer requirements. Our capabilities include custom braiding patterns, variable layer configurations, and specialized material combinations to meet specific operating conditions. This flexibility has made us the preferred processing partner for many international oilfield service companies.
The company’s processing services extend to complete hose assembly production, where we integrate the steel wire braided layer with compatible inner tubes and outer covers. Our assembly process includes precise end fitting crimping, pressure testing up to 1.5 times working pressure, and comprehensive quality inspection. Each finished product comes with detailed documentation including material certificates, test reports, and traceability records.

Quality Certification and Industry Recognition
Dingli Pipe Industry maintains API Spec Q1 quality management system certification and API Spec 7K certification for drilling hoses, demonstrating our commitment to international quality standards. These certifications, combined with our status as a Class II network member of CNPC, Sinopec, and CNOOC, position us as a trusted supplier in the global petroleum industry.
The company’s technical achievements have been recognized through multiple invention patents and utility model patents. Our R&D team continuously improves braiding technologies and material formulations, resulting in products with enhanced heat resistance, chemical compatibility, and fatigue life. These innovations have earned us the title of “Excellent Technology-Based Enterprise” in Hebei Province.
