E355 is a grade in the German standard DIN 2391. It is a cold-drawn precision Seamless Steel Pipe and a type of quilted pipe. It is a high-Precision Steel Pipe material processed by cold-drawing or hot-rolling. Because there are no oxide layers on the inner and outer walls of the precision Steel Pipe, 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 grinding tube is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr. The quilted steel pipe has the advantages of smaller outer diameter, high precision and small batch production, high precision of cold drawn finished product, good surface quality, more complex cross-sectional area of steel pipe, better performance of steel pipe, and dense metal. Main uses: steel pipes for hydraulic systems, steel pipes for automobiles, widely used in steel pipes for hydraulic systems, steel pipes for injection molding machines, steel pipes for hydraulic machines, marine steel pipes, EVA foaming hydraulic machinery, steel pipes for precision hydraulic cutting machines, shoe-making machinery , hydraulic equipment, high-pressure oil pipes, hydraulic oil pipes, ferrule joints, steel pipe joints, rubber machinery, forging machinery, die-casting machinery, construction machinery, high-pressure steel pipes for concrete pump trucks, sanitation vehicles, automotive industry, shipbuilding industry, metal processing, Military industry, diesel engine, internal combustion engine, air compressor, construction machinery, agricultural and forestry machinery, etc.

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.
