Socket Joint Steel Pipes

Tianjin Jumeng Steel Pipe Co., Ltd.'s Quality Socket Joint Steel Pipes are a pipe product that connects using a socket and spigot joint.  It is widely used in municipal engineering, building water supply and drainage, agricultural irrigation, and industrial fluid transportation. Utilizing an integrated molding process, the joints are sealed with sealing rings or welding.  It boasts convenient installation, excellent sealing performance, and outstanding pressure resistance, making it an efficient upgrade over traditional steel pipe connection methods.

Our Product's Core Advantages

1. Efficient Installation, Shortened Project Cycle

Socket Joint Design: Eliminating the need for complex welding or threaded connections, Durable Socket Joint Steel Pipes can be quickly connected manually or mechanically, increasing installation efficiency by over 30% compared to traditional steel pipes.

Flexible Site Adaptability: Supports multi-angle deflection (≤5°), effectively adapting to foundation settlement or construction errors, significantly reducing rework and installation costs.

2. Stable Structure, Safe and Durable

High-Strength Steel: Manufactured using high-quality Q235B/Q355B carbon steel, with a tensile strength ≥375 MPa and a yield strength ≥235 MPa, fully compliant with GB/T 3091-2015 national standard.

Double Sealing System: Equipped with natural rubber sealing rings (temperature range -40°C to 120°C), combined with an anti-slip socket inner wall design, ensuring zero leakage and a service life of up to 50 years.

3. Wide Range of Applications, Covering Multiple Scenarios

Our Socket Joint Steel Pipes are suitable for a wide range of applications, including:

Municipal Engineering: Urban water supply, drainage, and gas transmission pipelines

Building Construction: Fire sprinkler systems, HVAC water circulation systems, underground utility tunnels

Industrial Applications: Chemical fluid transportation, mine tailings pipelines, power plant steam systems

Agricultural Irrigation: Main pipelines for water-saving irrigation and drip irrigation networks

4. Optimized Cost Structure, Superior Cost-Effectiveness

Reduced Overall Project Costs: Reduced investment in labor, welding materials, and equipment helps lower total project costs by 15%–20%.

Easy Maintenance: Removable joints facilitate inspection, repair, and replacement, minimizing downtime and reducing long-term operating and maintenance costs.
