EN10305 E355 Honed Steel Pipe Hydraulic Tube. Hydraulic Seamless Steel Pipes are basically divided into fluid pipes and oil steel bobbins used in hydraulic systems, also known as honing pipe, while cold-drawn or cold-rolled precision seamless steel pipes also include hydraulic steel pipes. Cold-drawn or cold-rolled precision seamless steel pipes with high dimensional accuracy and good surface finish for hydraulic equipment. The raw material of the hydraulic steel pipe has undergone precise drawing, non-oxidative bright heat treatment (NBK state), non-destructive testing, the inner hole of the steel pipe is subjected to high pressure washing and pickling, the inner and outer walls of the steel pipe are treated with anti-rust oil, and the two ends are sealed for dust-proof treatment. . 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 piping in hydraulic systems, and Precision Steel Pipes for automobiles. The length is 6 meters (except for custom-made), and the delivery state 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 mechanical properties for steel pipes. client.

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.
