The cold-drawn seamless steel pipe has the characteristics of no oxide layer on the inner and outer walls, no leakage under high pressure, high precision, high finish, no deformation after cold bending, no cracks in flaring and flattening, and anti-rust treatment on the surface.
The basic process flow of cold drawing is: hot-rolled capillary—> capillary inspection and grinding—> capillary pickling—> re-inspection after capillary pickling—> cold drawing—> straightening before fine drawing—> pickling and lubrication —> Fine drawing —> Finished product pretreatment —> Warehousing.
Because of having so many advantages, the application scope of cold-drawn seamless steel pipe products continues to expand, and the necessity of its full play is becoming more and more prominent. For example, it can be used as supporting facilities for car positions, hardware tool positions, machinery and equipment machinery manufacturing, and textile equipment processing manufacturers.
To improve the quality of cold-drawn seamless steel pipe products, in the specific production and manufacturing, not only will the specific needs of today's large shopping malls be fully considered, but also the production process, anti-corrosion measures, docking methods, and high cost performance will continue to be analyzed. After the effective overall planning of channel steel products, it has a variety of advantages and characteristics in professional skills.
Mainly, the cold-drawn seamless steel pipe products we produce have excellent impact toughness, high compressive strength, stable performance, and in specific applications, the thermal expansion coefficient is small, and the concealed installation does not deform. In addition, it has excellent anti-corrosion effect to avoid external corrosion and internal corrosion to ensure a service life of 50 years. The inner cavity of the product is smooth and the resistance coefficient is small. Moreover, the newly upgraded dual-thermal fusion docking professional skills have been selected to promote safer and more economical development of commodity applications.
