High-Pressure Fitting Technology Breakthrough

Donghong Co., Ltd. has unveiled a comprehensive range of high-pressure pipe fitting solutions designed for the most demanding industrial environments — mining water supply, grouting, and tailings backfill operations.

Three core solutions stand out:

• High-Pressure Threaded Connections — Rated for up to 10.0 MPa, featuring O-ring axial sealing for reliable, rapid installation. Ideal for confined underground spaces where installation speed and space efficiency are critical.
• Integrated Flange Connections — One-piece flanged collar technology that locks steel wire reinforcement layers, paired with high-pressure retaining ring structures. Covers a wide pressure range of 4.0–10.0 MPa, adapting to various harsh mining conditions.
• New-Generation High-Pressure Fittings — Achieving 12 MPa performance for dn110–dn250 mm steel-wire mesh skeleton PE composite pipes, with over 300 hours of continuous testing at 60°C and 1.2×PN. These fittings have already been exported to overseas markets, proving their reliability under extreme conditions — without the need for metal inner cores, reducing both material and labor costs.

Welded Pipe Industry First Major Exchange Event

The China Iron & Steel Association (CISA) Welded Pipe Branch organized its inaugural “Explore New Quality · Weld the Future” industry study tour on July 26, visiting Youfa Group and Zhaolida Steel Pipe.

• Youfa Group has maintained China #1 welded pipe sales position for 20 consecutive years, serving as the benchmark for systematized operations and continuous innovation.
• Zhaolida Steel Pipe dominates the galvanized strip steel pipe niche, recognized as a national high-tech enterprise and Tianjin specialized and refined SME.
• CISA leadership emphasized four priorities: bridging government-industry communication, building practical exchange platforms, promoting industry self-discipline, and advancing green/low-carbon and digital transformation.

Panjin Steel Pipe Earns Provincial Industrial Design Center Certification

Shandong Panjin Steel Pipe Manufacturing Co., Ltd. has been certified as a Provincial Industrial Design Center, adding to its existing portfolio of:

• Provincial Industrial Design Center (new)
• Provincial Enterprise Technology Center
• Provincial R&D Center
• CNAS Nationally Accredited Laboratory

This four-platform innovation matrix enables Panjin to deliver integrated R&D, design, production and testing capabilities, focused on premium oil casing, high-pressure boiler tubes, precision tubes, and specialty high-temperature and corrosion-resistant pipes.

Record-Breaking 18,000 Tons Daily Shipment

Huayang Steel Pipe achieved a historic milestone on July 25, 2026 — 18,000 tons of single-day shipments, breaking all previous records since the company founding.

This capacity demonstration reflects full production line utilization with round-the-clock operations, multi-point synchronized loading and gantry crane precision handling, and efficient logistics with continuous truck convoys dispatching to project sites nationwide.

CNAS Accreditation for Kanghong Petroleum Pipe Testing

Kanghong Petroleum Pipe Material testing center has obtained CNAS laboratory accreditation (ISO/IEC 17025), meaning its inspection reports are now globally recognized under multilateral mutual recognition agreements.

Combined with existing API, PED, IATF16949, and nine major international classification society certifications, Kanghong quality system is now fully aligned with international standards for independent full-scope testing and overseas project audit compliance.

What This Means for International Pipe Buyers

These developments collectively illustrate a clear trajectory: Chinese pipe and fitting manufacturers are moving decisively upmarket, investing in R&D infrastructure, quality certifications, and production capacity that meet — and increasingly exceed — international expectations.

Whether you need high-pressure mining fittings, precision oil country tubular goods, or high-volume welded pipe delivery, the Chinese supply base is deeper, more capable, and more quality-assured than ever.
