The difference between precision steel pipe and cold drawn pipe
1. Cold drawn Cold drawing is to use a cold drawing machine to lengthen the metal pipe without heating. The advantage is that it does not need to be carried out at high temperature. get better mechanical properties. Process of cold drawn seamless steel pipe: round tube blank → heating → perforation → heading → annealing → pickling → multi-pass cold drawing → semi-finished pipe → heat treatment → straightening → hydraulic test (flaw detection) → marking → storage.
Introduction of special steel pipes for the automotive industry
Due to the particularity of automotive materials, all steel pipes are required to be beautiful in appearance, light in weight, safe to drive, stable and reliable. In order to ensure the aging of the steel pipe for automobiles, the material of the steel pipe is required to have good corrosion resistance and a certain period of service life. Therefore, according to the different parts of use, there are strict requirements on the material, dimensional accuracy, mechanical properties, process performance and surface quality of automobile steel pipes.
How to increase the stability of the spiral steel pipe
1) Small and medium-sized sections, wire rods, steel bars, medium-diameter steel pipes, steel wires and wire ropes, etc., can be stored in a well-ventilated material shed, but must be covered with pads. 2) Some small steels, thin steel plates, steel strips, silicon steel sheets, small-diameter or thin-walled steel pipes, various cold-rolled and cold-drawn steels and metal products with high prices and easy corrosion can be stored in the warehouse. 3) The site or
Where do construction machinery use steel pipes
Many steel pipes are used in the production of construction machinery, such as: some transmission parts (transmission shafts), support parts, and support rods. Wait, steel pipes are used in many places. Basically, except for the exterior decoration, the frame, transmission parts, support arms, etc. are all steel pipes. Take a closer look at whether it is a seamless pipe or a welded pipe. On construction sites, 20*2.5 should be used as the threading pipe buried in the air defense when starting to lay the foundatio

What are the characteristics of precision seamless pipes
Features of Precision Seamless Tube 1. High precision, saving the loss of machining user materials. 2. There are many specifications and a wide range of applications. 3. The cold-rolled finished product has high precision, good surface quality and good straightness. 4. The inner diameter of the steel pipe can be made into a hexagon. 5. The steel pipe has better performance and the metal is denser.
Cold-drawn steel pipe is a kind of steel pipe, that is, it is classified according to different production processes, which is different from hot-rolled (expanded) pipe. In the process of expanding the diameter of the capillary blank or the raw material tube, it is processed by multiple passes of cold drawing, usually on a single-chain or double-chain cold drawing machine of 0.5 to 100T. Cold-rolled (pulled) steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cr
How to solve the problem of difficult cutting of 304 stainless steel pipe
304 stainless steel pipe has alloy elements such as Cr, Ni, N, Nb, Mo, etc., which makes the steel pipe have good toughness and wear resistance, and is widely used in electrical appliances and mechanical equipment. However, its machinability is poor. In actual processing, cutting stainless steel welded pipes is often accompanied by the occurrence of knife breakage and knife sticking. Due to the large plastic deformation of stainless steel during cutting, the generated chips are not easy to break and stick, resulting in serious work hardening during the cutting process; how to solve the pro
Mechanical properties of precision bright seamless tubes | Uses and calculation methods
Precision bright seamless steel pipe is a kind of high-precision steel pipe material processed by fine drawing or cold rolling. Due to the advantages of no oxide layer on the inner and outer walls of the precision bright tube, 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 The oil cylinder can be a seamless pipe or a welded pipe. The chemical composition of the precision bright tube is carbon C, silicon Si, ma
Talking about the definition and construction technology of round pipe
Definition: A steel with open ends and a hollow concentric section, the length of which is larger than the circumference. Tube representation method The specifications of round pipes are expressed by external dimensions (such as outer diameter or side length) and inner diameter and wall thickness, and their sizes range from very small diameter capillaries to large round steel pipes with diameters of several meters. The main purpose of the round tube Round pipes can be used in pipelines, thermal equipment, machinery industry, petroleum geological dril
