ASTM A106 A53 Seamless Steel Alloy Large Diameter Thick Wall Seamless Steel Pipe

Carbon seamless steel pipe is a kind of strip steel. Steel pipe with hollow cross-section, a large number of pipes used to transport fluid, such as the transportation of oil, natural gas, gas, water and some solid materials such as pipes. Steel and round steel and other solid steel compared to the same bending strength in the same bending, lighter weight, is an economic section of steel, is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, Bicycle frames and steel construction scaffolding. The use of carbon seamless steel pipe manufacturing ring parts can improve material utilization, simplify the manufacturing process, save materials and processing time, such as rolling bearing rings, jackets, etc., has been widely used to manufacture steel pipe.

Seamless steel pipe is manufactured from solid, round steel billets that are pierced through the center with a mandrel. The billet is rolled and stretched through a hollow billet until it reaches a customer's specification. Because of its uniform shape and ability to withstand pressure and heat, seamless steel pipe is an ideal material for many industries.

ZhengDe Metal provides a variety of seamless pipe to meet your application needs, offering a large selection of sizes and lengths.

Three-roll pipe mill
The seamless steel pipe produced by the three-roll mill for hot-rolling seamless steel pipe has high precision. Because of the cross-rolling with the mandrel, the rolling action is repeated many times in one pass, which greatly improves the accuracy of the wall thickness and is not easy to produce. Defects such as scratches, ears, and green lines; the flexibility in production is large, and the pass size can be changed with the help of the clutch of the roll.

Adequate inventory
Standing inventory of carbon seamless tubes, seamless special-shaped tubes, alloy seamless tubes, precision tubes. Various types of seamless steel pipes with a specification of 5-426*0.5-60mm and a length of 2-16m. The cold-rolled precision bright tubes produced by our factory have smooth appearance, uniform wall thickness, no oxide layer, and high precision. The inner hole of the steel pipe can be divided into round type, spline type, plum blossom type, etc. It is widely used in automobiles, motorcycles, electric power, petrochemicals, ships, aerospace, bearings, pneumatic components, oil cylinders, boiler equipment, medical equipment, fitness equipment and other industries.

Attention to detail
No matter how to choose the hot-rolled seamless steel pipe, its quality cannot be ignored. It must be noted that there should be no defects on the surface, such as small cracks or scars, etc., and that the thickness of the pipe wall is the same to ensure uniformity. The physical comparison is still very important. Only after the basic comparison of the physical objects is done, can the steel pipes that meet the needs be selected. The processing technology of each seamless steel pipe is different, which will also affect its application field. Now it is generally processed by cold drawing and hot rolling, and the processing effect of the two and the application of steel pipes will also have certain differences.

Applicable scene
Hot-rolled seamless pipes specifically include low and medium pressure boiler steel pipes, high-pressure boiler steel pipes, seamless steel pipes for ships, petroleum cracking steel pipes, seamless steel pipes for high-pressure fertilizer equipment, oil jacket steel pipes, pipeline steel pipes, hollow sucker rods, and ordinary fluid steel pipes. , structural seamless steel pipes and imported alloy steel pipes, etc., with rich varieties and complete specifications, widely used in petroleum, chemical, electric power, boilers, ships, machinery and other industries, and have been sold all over the world.
