Description

These seamless cold drawn tubes for oil and gas pipeline comply with international standards such as ASTM, ASME, API, and DIN, including specifications like ASTM A106 and API 5L. Common materials include carbon and alloy steels such as St52, C45, and others that offer high strength and corrosion resistance. Outer diameters typically range from 30mm to 325mm, with wall thicknesses between 5mm and 30mm, ensuring versatility for various pipeline configurations.

The tubes are available in random lengths from 10 to 12,000 mm, and can also be custom-made to specific requirements. Ends can be beveled, plain, varnished, or fitted with protective caps to prevent damage during transport and installation. Surface treatments such as oiling are applied to enhance corrosion resistance and durability.

Seamless cold drawn tubes for oil and gas pipeline are widely used in both onshore and offshore applications, including gathering lines, transmission pipelines, and hydraulic systems. Their seamless nature ensures reliability under high pressure and harsh environmental conditions.

Delivery conditions include various heat treatment options such as normalized, annealed, or quenched and tempered, tailored to meet specific mechanical property requirements. Packaging is robust, often involving bundling, waterproof wrapping, and reinforced crating to ensure safe delivery.

With a minimum order quantity of 3 tons and flexible trade terms such as FOB, CFR, or CIF, these tubes offer a reliable solution for modern oil and gas infrastructure projects.
