Precision tubes are a high-precision steel tube material that is treated by cold extraction or heat roll。
Precision steel tubes are a high-precision steel pipe material that is treated by cold extraction or heat roll. Because of the absence of oxidation of the internal and external walls of the precision steel pipe, the advantages of high pressure-free, high light-purification, cold-tangled shapes, amplification, flat-fault-free products mainly used to produce aerodynamic or hydraulic components, such as gas cylinders or tanks, which can be seamless pipe or welded, the chemical composition of the precision steel pipe is carbon c, silicon si, manganesemn, sulphur s, phosphorus p, chromium cr. Precision steel tubes are a steel pipe material that is treated by cold extraction or heat rolling. @
Since the inner and internal walls of the precision steel pipe are not oxidized, subject to high pressure no leaks, high light purity, cold curves, extended mouths, flattening, and so on, products that are primarily used to produce gaseous or hydraulic components, such as gas cylinders or tanks, can be seamless pipes and welded receivers. The chemical components of the precision steel tube are carbon c, silicon si, manganese mn, sulphur s, phosphorus p and chromium cr。
Usual materials
The usual materials for precision seamless pipe are 10#, 20#, 35#, 45#。
There is much material that can be produced, and steel, as long as it is not hard, can be produced on an as-needed basis. For example: 10#, 35#, 16mn, 40cr
Production processes
Precision seamless pipes are usually produced by cold-rolling processes。
The processes are as follows:
Round steel piercing, sour wash, cold sawing, bundling
A sutureless acid wash, a cold saw, a bun
Characteristic advantages
Characteristics
1. High precision, which saves time spent on mechanical processing of user materials。
2. The specifications are numerous and are widely applied。
3. The cold rolled product is of high precision, surface quality and straightness。
The inner diameter of the tube may be hexagonized。
5. The tubes perform better and the metals are more dense。
What are the methods for thermal handling of precision steel tubes? It is usually divided into four main parts: a fire, a fire, a fire back, a fire back. When the fire is prepared, the entire cross-section of the work is required to provide the work with a micro-organism dominated by a thin needle-like pyramid. The return of fire through high temperatures resulted in a micro-organism dominated by an even return of the flames. Small-scale plants are not capable of analysing each furnace with gold, and generally do only hard tests, that is to say, the hardness after the fire reaches the hardness of the material, which is the hotness of the fire: it is the heat that just heats up to the critical temperature, transforms the steel into anorexia, and then cools it naturally in the air. It removes the mesh of co-dialysis steel seep carbon, fines crystallization and improves integrated mechanic performance for sub-requirements, and it is more economical to replace the off-fire process with positive fire for less demanding parts。
Acrylic fire: thermal handling of thermal cooling in the air by heating the steel above the critical temperature during the fire. It removes the mesh-based carbon seep in co-dialysis steel, and it is more economical for the sub-cosmetic steel to refine the crystals and improve the combined mechanics performance, and for less demanding parts to replace the fire retreat process with a positive fire. (b) pyramid fire: the iron is heated above the critical temperature at the time of the fire, warmed for a certain period of time, and is then quickly placed in the accelerant so that its temperature is drastically reduced, cooled at a speed greater than the critical cooling rate, and obtained thermal treatment of an unbalanced tissue dominated by the horse. It increases the strength and hardness of the steel, but reduces its plasticization. It is commonly used in gillfires such as water, oil, carbon water and saline solution, while high-speed steel can be “wind”, so high-speed steel is called “wind steel”。
The distinction between cold and ejaculation tubes
It's an ordinary carbon steel cryobaric tube, with the same size precision, and the tubes that are produced can be used in mechanical structures, fluid transport, etc.
You're talking about a piping tube that's more precise in size than an ordinary cold piping tube, but it's less efficient, so the piping is relatively expensive.
If you want to distinguish between these two tubes, it's mainly from the accuracy margin... And the surface mass, which is relatively bright.
And there's a tube, which is precise in size, which is a crumb, which is usually used on aerodynamics, hydraulics.
