Advantages of precision stainless steel pipe fittings. 1, there are requirements for dimensional accuracy, precision error < 0.05 mm. 2. There are requirements on the surface, and the surface of precision stainless steel pipe fittings is basically flawless. 3. There are requirements for raw materials. Good raw materials can make more precise stainless steel pipe fittings.

Precision stainless steel pipe is a kind of pipe that requires higher quality than conventional fittings. This high quality requirement is mainly reflected in dimension accuracy, pipe roundness, pressure resistance and so on. Additional, shape of cross section of this kind of pipe with thickness of pipe wall, pipe mouth size, pipe material and material will undertake classification, and type of pipe material affects utility directly.
One, pipe wall thickness: according to the wall thickness can be divided into thin-wall pipe and thick wall pipe; Thin-wall tube wall thickness and diameter ratio is less than 6%, the thinner the tube wall is the better heat dissipation performance, generally used as heat transfer tube, the inner tube wall requirements smooth not easy to scale; Suitable for central air conditioning, boiler, refrigeration and so on. And thick wall stainless steel pipe wall thickness and diameter ratio is greater than or equal to 6%, the weld should be completely welded, has good compressive resistance, mechanical properties, wear sand and other advantages, can be used as textile equipment, electroplating equipment, dyeing equipment parts.

Two, nozzle size: according to the nozzle size can be divided into small diameter precision stainless steel pipe and large diameter precision pipe; Small caliber pipe diameter between 0.7~8mm, it has good corrosion resistance and tensile resistance, the control of pipe mouth error is very strict, used in optical ruler line, thermal instrument and automation instrument. Large caliber pipe is generally used for fluid transportation. In addition to the requirements for the smoothness of the inner pipe wall, bright solid solution and pickling passivation are also needed to improve the corrosion resistance of the pipe. It is mainly used in industrial pipelines, nuclear energy, electric power and sewage treatment equipment.
