Product details

ST52 CK45 is a low alloy steel, equivalent to China's Q345D, commonly used as quilted steel pipe,
The quilted steel pipe is a kind of high-precision steel pipe material processed by cold drawing or hot rolling. Since the inner and outer walls of the precision steel tube have no oxide layer, no leakage under high pressure, high precision, high finish, no deformation in cold bending, no flaring, no cracks in flattening, etc., it is mainly used to produce products for pneumatic or hydraulic components, such as cylinders or Cylinder, can be seamless pipe. The chemical composition of the quilted steel pipe is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, and chromium Cr.
The quilted steel pipe is processed by rolling. Because the surface layer has residual compressive stress on the surface, it helps to seal the tiny cracks on the surface and hinders the expansion of erosion. Therefore, the corrosion resistance of the surface can be improved, and the generation or expansion of fatigue cracks can be delayed, thereby improving the fatigue strength of the quilted steel pipe.

1. The main production process of hot-rolled seamless steel pipe (main inspection process):
Tube blank preparation and inspection→tube blank heating→piercing→tube rolling→steel reheating→fixed (reduced) diameter→heat treatment △→finished tube straightening→finishing→inspection (non-destructive, physical and chemical, Taiwan inspection)→warehousing
2. The main production process of cold-rolled (drawn) seamless steel pipes:
Billet preparation→pickling lubrication→cold rolling (drawing)→heat treatment→straightening→finishing→inspection

Our products aye widely used in water engineering,petrochemical industry,chemical industry,electric power industry,agricultural irrigation,urban construction.

Used for liquid conveying:water supply and drainage.For gas transport:gas,steam,liquefier petroleum gas.

For structural use:as pile pipe,as a bridge;Pipes for wharves,roads and building structures.
