Cold Drawn Precision Tubes ACC. DIN2391 EN10305 - CTS

Destination and standards of seamless cold drawn precision tubes and pipes. Due to good quality, our precision tubes have been exported to Thailand, Malaysia, Indonesia, Korea, Turkey, Colombia, and Singapore, etc. Our factory has more than 10 years experience of cold drawn precision tubes and pipes. Cold Drawn Seamless Mechanical Steel tube and pipe Cold Drawn Seamless Mechanical Steel tube and pipe is produced by drawing tube through a die or cold rolling it to give it a more uniform diameter. For this reason Cold Drawn Seamless Mechanical Steel tube is stronger than other types of steel tube. Cold Drawn Seamless Steel tube and pipe can be used as a finished product or can be machined. Cold drawn erw pipeCold drawn erw pipe, which is one of the best choices for the production of multi-stage hydraulic cylinders.Its process is the same as that of precision seamless pipe cold drawing. It is precision drawn by precision resistance welding (ERW) and manufactured with EN. 10305-2 EU mechanical cold drawn carbon steel welded pipe standard.

Seamless cold-drawn precision steel pipes E235N (St 37.4) and E355N (St. 52.4) according to the EUs EN 10305-4 standard a) E235N (St 37.4) NBK Normalized, phosphated and oiled inside and outside b) E235N (St 37.4) NBK/ZN Normalized, electric zinc plated with Cr-VI-free passivation c) E355N (St 52.4) NBK Normalized Difference between Precision Steel Pipe and Seamless Steel 1, the main features of seamless steel pipe is no welding seam, can withstand greater pressure. The product can be very rough as-cast or cold-drawn parts. 2, precision steel pipe in recent years there are products, mainly within the hole, the outer wall size has a strict tolerance and roughness. Characteristics of precision seamless steel tube 1.

Precautions for Seamless Steel Pipe Production - OilVoice

Jan 10, 2020 · The quality of annealing affects both the performance of the steel pipe and the removal of scale. Cold drawn precision steel pipes need to be equipped with non-oxidizing bright annealing furnace equipment. 5. Pickling During the sulfuric acid pickling process, precision seamless steel pipes easily form "black slag" mainly composed of Fe2O3 and Fe3O4, and form surface black spots in Precision ERW Welding GI Steel Pipe Making Machine A:Cold drawn seamless steel tube is a kind of precise cold drawn seamless pipe used for mechanical structure and hydraulic equipment with high dimensional accuracy and good surface Hot Tags:precision erw welding gi steel pipe making machine, manufacturers, factory, prices, for sale Precision cold drawn tube - Alloy Pipe, Tubes, Ceramic Cold-rolled tube refers to steel product that is through cold drawing, cold-formed, cold drawn, cold plate or strip processed at room temperature. Annealing and quenching of cold drawn steel The annealing of cold drawn steel is commonly used in the production of preliminary heat treatment process.

Welding pipes, Precision cold drawn steel tube production

Precision cold drawn steel tube production process Pipe weld cracks often follow different mechanisms can be divided into two types of thermal cracking and cold cracking. It is produced by the thermal cracking of a liquid to a solid state crystallization process in Surface Quality Analysis of High Precision Cold Drawn (1) Cold drawn seamless steel pipe directly into the cylinder, the quality can not be guaranteed, it is best to stay 0.2mm (wall thickness) honing, grinding and then processing use. (2) Cold drawn seamless steel pipe inner hole defect is the impact of the cylinder bore hole surface quality of the main reasons.
