JIS G3445 STKM13C Honing Steel Pipe is a high-Precision Steel Pipe material processed by cold drawing or hot rolling. Due to the characteristics of no oxide layer on the inner and outer walls of the Precision Steel Tube, 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 for the production of pneumatic or hydraulic components, such as cylinders or cylinders, Can be seamless tube. The chemical composition of quilted Steel Pipe is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr. The steel pipe produced has high precision and good finish, and there is no oxide layer on the inner and outer walls of the steel pipe. Mechanical properties can be bent at any angle without deformation. It is mainly used to prepare steel pipes in the oil circuit of hydraulic systems, also known as hard pipes in hydraulic systems and Precision Steel Pipes for automobiles. The length is 6 meters (except for custom-made), and the delivery status is NBK (normalizing), GBK (annealing), BKS (stress relief annealing). The main materials are ST35, ST37.4 (10#), ST45 (20#), ST55 (35#), ST52 (16Mn), etc., which can meet the requirements of high precision, high finish, tensile strength and high steel pipe.
Processing advantages 1. Improve the surface roughness, the roughness can basically reach Ra≤0.08μm. 2. Correct roundness and ellipticity ≤0.01mm. 3. Improve the surface hardness, eliminate stress and deformation, increase the hardness by HV≥4°4, have a residual stress layer after processing, and increase the fatigue strength by 30%. 5. Improve the quality of fit, reduce wear, and prolong the service life of parts, but the processing cost of parts is reduced.

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.
