Product Introduction
Seamless pipe is a long steel strip with a hollow cross-section and no seams around it. It is made by punching a whole round steel bar, without welds on the surface, and is usually rolled from ordinary carbon structural steel, low alloy structural steel or alloy structural steel. Seamless pipes are widely used in various fields, including machinery manufacturing, oil drilling, shipbuilding, boiler manufacturing, etc.
Features
Excellent mechanical properties: Seamless steel pipes have high tensile strength and yield strength, and can withstand large external forces without deformation or rupture.
Good toughness: When subjected to impact loads, seamless steel pipes can absorb a large amount of energy without brittle fracture.
Good processing performance: Seamless steel pipes are easy to cut and weld, and the welded joints have high strength and good sealing.
Good corrosion resistance: According to different use environments and medium requirements, seamless steel pipes can be made of a variety of corrosion-resistant materials, such as stainless steel, alloy steel, etc.
High dimensional accuracy: The production process of seamless steel pipes adopts advanced rolling and processing technology, which can accurately control the dimensional parameters of the steel pipes such as outer diameter, inner diameter and wall thickness.
Production process
Application
Petroleum, natural gas and chemical industry: Seamless steel pipes are widely used in pipelines in the petroleum, natural gas and chemical industries, including oil well pipelines, fertilizer plants and refineries. Seamless steel pipes play a vital role in these industries because they can withstand high pressure and high temperature conditions.
Heat, heating and hydraulic engineering: In heat, heating and hydraulic engineering, seamless steel pipes are used for boilers, heating pipes, heat storage and condensers in shipbuilding and machinery manufacturing. They are not only strong and durable, but also can withstand great pressure.
Manufacturing industry: Seamless steel pipes are also widely used in the manufacturing industry, such as bearings, hydraulic pipes and mechanical structural parts of automobiles and motorcycles. Due to their light weight and high strength, seamless steel pipes perform well in the manufacture of structural parts and mechanical parts.
Steel structure engineering: In steel structure engineering, seamless steel pipes are used for load-bearing columns, beams, bridge structures, docks, space launch towers and sound insulation walls of buildings. They are not only strong and durable, but also can withstand great pressure.
Water resources development: Seamless steel pipes are also widely used in water resources development, such as water pipes, water pipelines, water pumps, blowers, turbines and other equipment in hydropower stations. Due to its good pressure resistance, seamless steel pipes perform well in these equipment.
Civil engineering: In civil engineering, seamless steel pipes are used for foundation pit support, high-pressure tunnel engineering, and underground mining support. They can withstand high pressure and corrosive environments to ensure the safety and stability of the project.
Daily application: Seamless steel pipes are also used in some mechanical equipment brackets and connectors in daily life. Although they are not conspicuous, they support the operation of the entire equipment.
