The so-called cold drawn precision steel pipe is generally used for structural steel pipes with high precision and good surface finish. In the case of small and medium-sized construction projects, the use of mechanical structures or hydraulic equipment is essential, and cold drawn precision steel tubes can greatly reduce machining time, improve material utilization, reduce construction costs, and improve product quality.
Seamless steel tubes with small dimensional accuracy and good quality should be cold rolled, cold drawn or a combination of the two. Cold rolling usually causes the steel pipe to be rolled in an annular hole type composed of a circular hole groove and a stationary tapered head. The cold drawn steel pipe is carried out on a single-chain or double-chain cold drawing machine of 0.5 to 100T.
Cold drawn precision steel pipe features: outer diameter is smaller than ordinary steel pipe, high precision, superior performance, high precision of finished products, good surface quality of steel pipe, complex cross-sectional area of steel pipe, and can be produced in small batches. Compared with ordinary steel pipes, the advantage of cold drawn precision steel pipes is that they have no weld seams and can withstand large pressures.
