St52 Alloy Steel Seamless Hydraulic Cylinder Honed Pipe
Short Description:
ST52 hot rolled seamless steel pipes come under the DIN 2391 specification. The DIN 2391 St52 steel pipe is made with a chemical composition of carbon, silicon, manganese, phosphorous, and sulfur. These pipes are very strong and designed with enhanced corrosion resistance properties. DIN 2391 ST52 steel pipe possesses excellent mechanical properties.
we can cut the St52 seamless steel pipe into the length you demand, and can make the surface to be bright by milling and grinding at the Lathe, and can grind the outer diameter and wall thickness to be the dimension you demand.If the sizes are not available from the standard common stock sizes, and the quantity are not enough for the new production, then we need process the stock larger seamless pipes into the sizes you need. And we also can make steel pipes deep processing.
Size: 34mm-610mm.
W.T.: 3.5mm-50 mm.
Shape: Round.
Production type: Hot rolled or Hot expended .
Length: Single random length/ Double random length or as customer’s actual request max length is 12m

Straightening
Post annealing, the goods are passed through a seven roller straightening machine to achieve proper straightening of the tubes.
Eddy current
Post straightening, each tube is passed through eddy current machine to detect for surface cracks and other defects . Only the tubes that pass eddy current are fit for delivery to customers.
Finishing
Each tube is either oiled with corrosion resistant oil or varnished for surface protection and corrosion resistant as per customers requirement, each tube end is covered by plastic end caps to avoid damage in transit, the marking and specs are put and the goods are ready for dispatch.
ST52 Hot Rolled Carbon steel seamless pipes are extensively applied in the nuclear device, gas conveyance, petrochemical, shipbuilding and boiler industries, with characteristics of high corrosion resistance combined with suitable mechanical properties.
- Nuclear device
- Gas conveyance
- Petrochemical industries
- Shipbuilding and boiler industries
