Seamless Steel Pipes
Overview:
Seamless steel tubes are hollow‑section steel products manufactured without any welding seam, produced via either hot‑rolled or cold‑drawn processes.
Our seamless tube portfolio covers a comprehensive range of grades & specifications, including general‑purpose carbon steel tubes, high‑temperature boiler tubes, heat‑exchanger tubes, alloy boiler tubes, API 5L line pipes, as well as API 5CT oilfield tubing & casing.
Manufactured in compliance with major international standards: ASTM / ASME (A106, A53, A210, A213, A179, A192), API 5L, API 5CT. Widely used for transportation of oil, natural gas, water and other fluids; also for boiler superheaters, economizers, heat exchangers, pressure‑vessel components, oil‑well casing & tubing, and mechanical structural applications for global energy, petrochemical, power‑plant and pipeline projects. Both hot‑rolled and cold‑finished execution are available.
Key Features:
- Seam‑free construction: Produced from solid steel billets by hot piercing or cold‑drawing. Eliminates weld‑related defects for enhanced safety under high‑pressure and high‑temperature service.
- Broad product coverage: General‑purpose fluid pipes, power‑station boiler & heat‑exchanger tubes, line pipes, oil‑field tubing and casing are all within our supply scope.
- Multiple international standard compliance: Meet ASTM‑ASME specifications (A106, A53, A179, A192, A210, A213), API 5L for transmission pipelines and API 5CT for oil‑well casing & tubing, suitable for international bidding projects.
- Diverse material grades: Carbon steel, medium‑carbon steel, low‑alloy ferritic grades available; alternative grades can be negotiated according to client requirements.
- Excellent high‑pressure & high‑temperature performance: Suitable for harsh working conditions in power boilers, heat exchangers, petrochemical and on‑site oil‑gas well service.
- Flexible manufacturing options: Supplied as hot‑rolled or cold‑drawn, custom cut‑to‑length service is available.
-
Strict quality control: Hydraulic pressure testing, ultrasonic and other non‑destructive inspections plus mechanical & chemical lab testing are performed for each production batch before shipment.
