Dfps Corrosion Resistant Exhaust Flexible Joint Steel Bolt-Cap Type Ss Round Tube Pipe

Product Description

Product Description

The fully self-anchoring (seismic-resistant) flexible-joint steel pipe is an advanced pipeline system featuring a simple structure, scientific design, and enhanced anti-seismic and anti-leakage performance. It is specifically developed to solve the common issues of traditional pipelines—poor seismic resistance, frequent joint leakage, and complicated installation. The product complies with the international standard ISO 16134: Seismic design and subsidence control for ductile iron pipeline systems, and its seismic Performance surpasses similar Japanese and American seismic pipe types, with third-party testing confirming a 20% improvement in displacement resistance.
Through an innovative design that requires only one additional locking ring, the system achieves three major breakthroughs:
Eliminates concrete thrust blocks, significantly reducing foundation construction costs.
Prevents joint pull-out and leakage, greatly lowering long-term operation and maintenance risks.
Removes the need for welding and secondary anti-corrosion, shortening construction time by over 50%.
Installation efficiency is six times higher than traditional pipe systems, while eliminating the risk of burst or leakage caused by stress concentration in welded pipes. The system provides both all-direction self-anchoring resistance against pull-out and flexibility to accommodate ground settlement, ensuring high stability and reliability in complex geological conditions.

Dongfang Pipeline is a leading developer of anti-seismic self-anchored steel pipe systems, offering fast installation, zero leakage, and superior flexibility compared with traditional welded or ductile iron pipelines.
Our patented self-anchoring joint eliminates the need for thrust blocks, reduces installation time by over 80%, and ensures reliable performance under ground settlement, vibration, and seismic conditions.
Trusted in municipal water supply, firefighting networks, long-distance transmission, and trenchless projects, our system delivers high strength, high safety, and high installation efficiency for demanding engineering environments.

Company Profile

Dongfang Pipeline Solutions (referred to as "Dongfang Pipeline") is a leading engineering pipeline system manufacturer and the chief drafter of China's national standard for steel wire reinforced PE composite pipes. Established in Shunde, Guangdong Province, the company has grown into a comprehensive provider integrating R&D, production, testing, engineering technical support and complete pipeline system solutions.

For more than two decades, Dongfang Pipeline has focused on the advancement of polymer composite pipeline technology, offering high-reliability products for industrial engineering, municipal and public engineering, and large-scale civil projects. Our product portfolio covers HDPE water supply pipelines, steel wire reinforced composite pipelines (SRCP), multi-layer steel wire composite pipelines for mining, and a full set of supporting injection-molded fittings. All products are produced with 100% virgin PE100 materials, ensuring long-term mechanical integrity and superior performance.

Dongfang Pipeline operates a CNAS-accredited multifunctional laboratory, enabling full in-house testing aligned with GB, ISO, and international standards. This ensures strict quality control across raw materials, structural performance, hydrostatic pressure resistance, impact behavior, long-term creep properties, and composite layer bonding. The CNAS accreditation positions the company among China's most advanced testing-capable pipeline manufacturers.

The company currently holds 36 invention patents and 34 utility model patents, reflecting its continuous commitment to innovation in composite reinforcement structures, pipe-fitting compatibility, and engineered connection methods. All core pipe and fitting products are independently developed and manufactured, guaranteeing 100% system compatibilityand engineering reliability—especially under demanding installation conditions such as deep burial, high pressure, corrosive media, and dynamic load environments.

Dongfang Pipeline products have been widely adopted in major national landmark projects, demonstrating the reliability and engineering value of our technology in diverse and extreme environments. Representative projects include:
· Beijing National Stadium (Bird's Nest)
· Minmetals Jianghua Rare Earth Project
· Wenchang Satellite Launch Center, Hainan
· Jiuquan Satellite Launch Center, Gansu
· Xizang Xianglong Mining Project
· Zijin Mining Group Projects

Beyond individual flagship projects, Dongfang Pipeline has established extensive application coverage across core national infrastructures. To date, our products have been installed in:
· 35 major ports in coastal and river-port regions
· 51 airports, including high-altitude, tropical, and coastal environments
· 18 large-scale sports stadiums, including national and provincial games venues
· Thousands of municipal engineering projects across water supply, drainage, and integrated pipeline corridors
· Extensive industrial projects, including mining, chemical plants, smelting operations, manufacturing parks, and power-related installations

In the specialized field of firefighting engineering, Dongfang Pipeline is one of China's established suppliers of composite firefighting pipelines. Our SRCP pipe has been applied in over 5,000 certified firefighting projects across the country, serving high-rise commercial buildings, industrial facilities, logistics centers, metro stations, tunnels, and large public complexes. SRCP's pressure resistance, corrosion resistance, and ease of installation make it one of the most reliable choices for modern firefighting engineering systems.

Supported by robust manufacturing technology and complete system integration capabilities, Dongfang Pipeline continues to advance the development of intelligent and durable pipeline networks for China and global markets. Our long-standing cooperation with government agencies, EPC contractors, municipal authorities, mining groups, and industrial engineering firms demonstrates our ability to support large-scale and high-complexity projects from design coordination to on-site implementation.
