Low Temperature Heat Exchanger 6m 12m Custom Size Factory Price Sells 16mndg Seamless Steel Pipes

16MnDG seamless steel pipe implementation standard - GB/T18984-2016, the materials in this type of low-temperature seamless pipe standard are: 09MnDG, 10MnDG, 16MnDG, 09Mn2VDG, of which the chemical composition of 16MnDG seamless pipe is the same as that of American standard A333Gr.6 low-temperature steel pipe Basically the same as the mechanical properties.
16MnDG seamless steel pipe is a kind of material in low temperature resistant seamless pipe, also known as 16MnDG low temperature steel pipe, its overall material is the prototype of 16Mn, the suffix letter DG means low temperature and high pressure, that is to say, at minus 40 ºC Seamless steel pipes that can withstand high-strength pressure in low-temperature environments
16MnDG seamless steel pipe products are applied to: seamless steel pipes for -45ºC~-195ºC low-temperature pressure vessel pipes and low-temperature heat exchanger pipes

Zhengde hot-rolled seamless steel pipe is a long strip of steel with a hollow section and no joints around it. The steel pipe has a hollow cross-section and is widely used as a pipeline for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, seamless steel pipe is lighter in weight when the bending and torsional strength is the same. It is an economical section steel and is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes and automobile transmission shafts. , bicycle racks and steel scaffolding used in building construction, etc. The use of seamless steel pipes to manufacture ring parts can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing hours, such as rolling bearing rings, jack sets, etc., which have been widely used in steel pipes. Hot-rolled seamless steel pipe is also an indispensable material for various conventional weapons. Gun barrels, barrels, etc. must be made of steel pipes.

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.
