42crmo seamless steel pipe 1. The main purpose of general seamless steel pipe is cold rolled general carbon steel, low alloy steel or alloy tool steel. There are many productions, and the key is to be used as a liquid conveying pipe or a structural part.
1. The process of 42crmo seamless steel pipe is as follows
1. 42crmo seamless steel pipe When the seamless pipe and the straight seam pipe have the same diameter and wall thickness, the pressure and robustness of the seamless pipe are much greater than that of the straight seam pipe. The production process of straight seam welded pipe is simple, low in cost, fast in development and high in production efficiency. Seamless steel tubes have hollow sections and are widely used in pipelines for conveying fluids, such as oil, natural gas, natural gas, water, and some solid substances.
2. 42crmo seamless steel pipe hot-rolled seamless steel pipe is divided into general steel pipe, stainless steel pipe, high-pressure boiler steel pipe, medium-pressure boiler steel pipe, low-pressure boiler steel pipe, petroleum cracking steel pipe, alloy steel pipe, geological steel pipe and other steel pipes. Widely used in the manufacture of parts and mechanical parts, such as oil drilling tools, transmission shafts, bicycle frames, and seamless steel pipes for steel scaffolding construction to make round parts, etc., can improve the utilization efficiency of raw materials, the manufacturing process is simple, and raw materials are saved And production construction time, has been widely used in the manufacture of seamless steel pipes.
3. 42crmo seamless steel pipes, steel pipes are very widely used, used for conveying fluid pipelines, petroleum pipelines, chemical pipelines, electric power companies, thermal company pipelines, steam pipelines, hydropower station pressure steel pipes, thermal power generation, water supply and drainage pipelines, tap water and other long-distance Conveying pipelines, pile foundations, bridges, steel structures and other engineering fields.
2. Experience summary of 42crmo seamless steel pipe
1. The maximum diameter of 42crmo seamless steel pipe is 900mm, and the minimum diameter is 4mm. C. Supply according to pressure test.

Our Advantages
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.
Quality first: production and inspection in strict accordance with production standards;
Price advantage: discounts based on real market prices;
Transaction security: There will be no loss of customer funds;
After-sales guarantee: the customer's problem is our problem;
Long-term cooperation: quality assurance, price advantage, sincere service can last for a long time.
