ASTM A672 Grade C55, Gr. C60, Gr. C70 Welded Pipe

High-strength carbon steel welded pipe manufactured to ASTM A672 requirements, available in Grades C55, C60 and C70. These welded pipes are engineered for pipeline transportation and structural applications where reliable welded construction and consistent mechanical performance are required.

Key features

• Available grades: ASTM A672 Grade C55, Grade C60, Grade C70.
• Carbon-steel chemistry suitable for general pipeline, hydrocarbon and industrial service (contains carbon and typical alloying elements used to meet grade requirements).
• Welded construction for efficient, cost-effective production and consistent dimensional control.
• Manufactured and tested to meet ASTM A672 standard requirements; third-party inspection and testing can be arranged on request.

Typical applications

• Cross-country and on-site pipeline systems for natural gas, petroleum, water and other fluids
• Petrochemical and refinery piping and equipment
• Offshore and onshore structural piping and supports
• Power generation (thermal, solar, nuclear balance-of-plant piping) and industrial process lines
• General mechanical and structural applications requiring medium- to high-carbon welded tubing

Quality & testing

• Supplied with material test certificates traceable to ASTM A672
• Common quality checks include chemical analysis, dimensional inspection and mechanical testing per standard; additional NDT (UT, radiography) and hydrostatic testing available upon request
• Third-party inspection and certification can be arranged for large or critical orders

Available options & supply details

• Diameters, wall thicknesses and lengths to customer specification (please specify OD, wall thickness, and length when requesting a quote)
• End finishes, beveling, protective coatings (e.g., primer, anti-corrosion wraps) and packaging options available
• Packaging suitable for export shipping; labeling and documentation provided per buyer requirements
