Product Description

Product Description

Production of seamless pipe

The process begins with solid steel rounds, or billets, being cut to a specified length and sent through a walking-beam reheat furnace, where temperatures reach nearly 2,300°F. After exiting the reheat furnace, the preheated rounds are turned into a tube shell in the rotary piercing mill as the billets are cross-rolled between two barrel-shaped rolls at a high speed. The seamless shells enter mandrel mill, where they are rolled over a retained mandrel to provide the needed OD size and wall thickness for the next process. The process is carefully monitored using a state-of-the-art hot-wall measuring system. The shells are then reheated for final forming in a 24-stand stretch-reducing mill, where outside diameters are formed to customers' exacting specifications. Wall thickness is again verified using a hot-wall measuring system. After being rotated and advanced on the walking-beam cooling bed, the pipes are batch cut and transferred to an in-process storage area, where they are handled by computer-controlled gantry cranes.

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.
