Models and Options
Seamless pipes are available in both hot rolled and cold drawn conditions. Hot rolled pipes offer economical solutions for general applications, while cold drawn pipes provide tighter tolerances and improved mechanical properties. End types include plain, beveled, and threaded, with various coatings as needed.
Materials and Structure
Manufactured from solid carbon steel billets, which are heated and pierced to create a hollow tube without any welding. The absence of a seam provides uniform strength and resistance to pressure, making it suitable for critical applications. Material grades Q235B and ASTM A53 are available, with possible additions of alloying elements for enhanced performance.
Applications
Designed for high-pressure services in oil and gas industry, such as downhole tubing, casing, and transmission lines. Also used in hydraulic systems, boiler tubes, and mechanical components where high reliability is essential.
Customization
We can customize OD, WT, length, end finish, and surface treatment. For high-pressure applications, we can also provide additional testing such as hydrostatic tests and ultrasonic inspection. Contact us for your specific requirements.
FAQ
What is the difference between hot rolled and cold drawn seamless pipe?
Hot rolled pipes are formed at high temperatures, offering cost-effectiveness for standard applications. Cold drawn pipes are processed at room temperature for tighter tolerances and higher strength.
Can this pipe be used for high temperature services?
Yes, depending on the grade and specifications, it can be used in elevated temperature environments. Please discuss your application with our engineers.
What surface treatments are available?
We offer black painted, oiled, galvanized, 3PE, FBE, and pickling treatments to suit corrosion protection needs.
Do you provide certificates?
Yes, we provide material test reports and can arrange third-party inspection.
What is the MOQ?
MOQ is flexible based on specifications and customer requirements.
