Large Diameter EN10216 P265GH ASTM A106 Seamless Steel Pipe for High Pressure Applications

Seamless pipe is a long strip of steel with hollow section and no joint around it. Key characteristics include:

• Thicker wall thickness provides greater economy and practicality
• Thinner wall thickness requires higher processing costs
• Limited precision with potential for uneven wall thickness and surface imperfections
• Requires offline detection and shaping processes
• Ideal for high pressure, high strength, and mechanical structure applications

Seamless steel pipes are widely used in industries requiring high strength, pressure resistance, and reliable performance. Their uniform structure and absence of weld seams provide excellent mechanical properties and higher safety compared to welded pipes.

Primary applications include:

• Oil and gas transportation systems
• Water supply infrastructure
• Boiler and heat exchanger equipment
• Pressure pipelines
• Construction and structural engineering (load-bearing structures, scaffolding, steel frameworks)
• Mechanical manufacturing (shafts, cylinders, hydraulic systems, precision components)
• Shipbuilding, power plants, petrochemical industries, and industrial equipment manufacturing

Seamless steel pipes are manufactured from solid round steel billets without welded seams through a comprehensive process:

• Heating high-quality steel billets to high temperature
• Piercing at center using rotary piercer to form hollow tube
• Elongation and reduction to required dimensions through hot rolling processes
• Optional cold drawing or cold rolling for higher dimensional accuracy
• Heat treatment (normalizing, quenching, tempering) to improve mechanical properties
• Surface treatments (black finish, pickling, phosphating, oiling, painting)
• Comprehensive inspection including dimensional checks, mechanical testing, and non-destructive testing

Packaging: Container or bulk ship delivery with standard export seaworthy packaging suitable for all transport modes. Customizable packaging available per requirements.
