What are the characteristics of seamless steel pipe?
PT Donguan produces seamless pipes with uniform organization throughout their length. They are made from a seamless manufacturing process that ensures consistency in size, wall thickness, and mechanical properties. This product consistency makes them very reliable in applications that require strict product specifications.
As the name suggests, seamless steel pipes are seamless steel pipes without welds or joints. Since there are no welds, the possibility of air leakage or failure is avoided. PT Donguan ’s seamless steel pipes also have excellent corrosion resistance and improved pressure resistance.
PT Donguan ’s seamless steel pipe surface is smooth and beautiful. Since there is no weld or seam, the possible unevenness and unevenness of the welded pipe are avoided. The smooth appearance of the seamless tube allows for efficient fluid flow, reducing friction and also reducing debris and dirt collection.
Seamless pipe diameter range from small to large. Outer diameter, wall thickness, length PT Donguan can be customized according to customer ’s specific requirements.
What is the Application of PT Donguan seamless steel pipe?
Oil And Gas Industry
Seamless alloy pipes are mainly used in the oil and gas industry to transport crude oil, natural gas and petroleum products. They are used in pipelines, offshore drilling, refining and petrochemicals. Tubes used in this industry are generally high strength carbon or alloy steel, corrosion resistant and high pressure resistant.
Automotive Industry
Seamless tubes are widely used in the automotive industry, especially in exhaust systems. It is generally made of stainless steel because of its high-temperature resistance, corrosion resistance, and vibration resistance. Seamless stainless steel exhaust systems improve engine power, reduce exhaust emissions, and also increase the life of the entire system.
Construction And Infrastructure
Seamless tubes are widely used in the construction industry. They are used in buildings, bridges, tunnels, and other infrastructure projects. Tubes can be building components such as columns and beams, and can also be used in plumbing, HVAC (heating, ventilation and air conditioning) and fire suppression systems.
For The Power
Seamless pipes have an important place in the power industry. They are used to transport steam, water and other liquids in conventional power plants and nuclear power plants. Seamless tubes are used in boilers, heat exchangers, steam turbines, etc. These tubes are generally made of alloy or stainless steel and can work in harsh operating environments.
