Product introduction
Product Description
ERW Carbon Steel Pipe For Gas Transmission 89mm is a professional straight seam electric resistance welded steel pipe specially customized for urban and industrial gas transmission projects. Adopting high-frequency ERW welding technology and standardized national and international production standards, this 89mm conventional small and medium-diameter pipe features smooth inner and outer wall, uniform thickness, excellent welding tightness and stable pressure resistance. It is specially designed for low and medium-pressure natural gas, coal gas and town gas transmission systems.
All 89mm gas transmission steel pipes undergo 100% hydrostatic pressure test and weld non-destructive inspection, with no air leakage, no weld defects and stable long-term operation performance. This specification is a universal mainstream size for gas branch pipelines, residential gas access and factory gas supply pipelines. With low fluid resistance, easy construction and high cost performance, it is the most widely used standard pipe for municipal gas transmission supporting projects.

Core Product Advantages
Ultra-high Airtightness for Gas Safety
Adopting precision high-frequency ERW welding technology, the weld seam is integrated with the pipe body without tiny gaps, cracks or slag inclusions. Every pipe passes strict air pressure and hydrostatic testing, completely avoiding gas leakage risks. It meets the safety standards of municipal gas transmission engineering and ensures long-term safe and stable gas delivery.
Standard 89mm Universal Matching Size
89mm outer diameter is a mainstream standard size for gas branch pipelines and household gas inlet pipelines. It perfectly matches all conventional gas pipe fittings, elbows, tees, valves and flanges on the market. The high compatibility greatly simplifies on-site docking work, improves construction efficiency and reduces auxiliary material costs.
Low Fluid Resistance & Stable Gas Delivery
The inner wall of the pipe is smooth and flat without welding burrs and bulges, which effectively reduces gas transmission resistance, ensures stable gas flow and pressure balance, and avoids gas pressure fluctuation and pipeline blockage during long-term operation. It guarantees stable gas supply for communities, factories and commercial buildings.
Excellent Structural & Pressure Resistance
Made of high-quality Q235B/Q355B/L245 carbon steel, the pipe body has uniform structure, good toughness and compression resistance. It can adapt to buried and exposed laying environments, resist external soil pressure and slight construction impact, and maintain structural stability during long-term gas pipeline operation.
High Cost-Effective Gas Pipeline Solution
Compared with seamless pipes, ERW welded pipes have lower procurement costs while fully meeting gas transmission safety and pressure requirements. With stable quality, low failure rate and almost no later maintenance, it is the preferred cost-effective pipe for large-scale municipal gas renovation and new gas supply projects.

Manufacturing Process
Raw Material Inspection: Adopt qualified carbon steel strips, strictly inspect chemical composition and mechanical properties to meet gas pipe production standards.
Precision Continuous Forming: The steel strip is rolled and formed at a constant speed to ensure uniform roundness and consistent wall thickness of 89mm pipe.
High-frequency Welding: Automatic high-frequency resistance welding, realizing integrated forming of weld and pipe body with high bonding strength.
Internal & External Burr Removal: Polish welding burrs thoroughly to ensure smooth inner and outer walls and reduce gas transmission resistance.
Weld Stress Relief: Online heat treatment eliminates welding stress to prevent weld cracking and improve pipe toughness and safety.
Sizing & Straightening: Precision sizing and straightening to ensure 89mm standard outer diameter and high pipe straightness.
Fixed-length Cutting: Cut according to customer required length with neat and burr-free pipe ends.
Full Safety Inspection: 100% hydrostatic test, weld non-destructive flaw detection and air tightness test for gas safety.
Anti-rust Treatment & Packaging: Surface oiled anti-rust, standard marking and professional sealed packaging for transportation.
