Top Suppliers Seamless Steel Pipe SA213 P91/T11 SA355 13crmo4 SA192 SA53 A160 St37 St52 1020 Round Alloy Carbon Seamless Steel Pipe/Tube

Short Description:

Cold drawn seamless steel pipe is made from a seamless steel hollow. It is further processed by cold drawing over a mandrel, to control the ID, and through dies to control the OD.  CDS is superior in surface quality, dimensional tolerances and strength when compared to hot finished seamless tubing.Due to the characteristics of high-precision, in precision machinery manufacturing, auto parts, hydraulic cylinders, construction (steel sleeve) industry has a very wide range of applications.

Size: 16mm-89mm.

W.T.: 0.8mm-18 mm.

Shape: Round.

Production type: Cold drawn or cold rolled.

Length: Single random length/ Double random length or as customer’s actual request max length is 10m

Annealing

After the goods are cold drawn to sizes, the tubes are put on annealing furnace for heat treatment and normalising.

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.
