Stainless steel super pipe has good plasticity and toughness, but it is easy to produce work hardening. If this kind of work hardening is misunderstood as high hardness, so as to reduce the back cutting amount and feed amount during cutting, the edge of the cutting tool will be easily damaged in the part where the work hardening is always cut. However, as long as the back cutting amount and feed amount are increased, stainless steel is not difficult to cut. Stainless steel super pipes have high strength, so they are generally stacked together.

However, certain principles should be followed when stacking, otherwise the stainless steel pipe may be damaged or inconvenient to take. The purpose of ventilation is to prevent the thin-walled stainless steel pipe from being in the humid air for a long time, so that the moisture can be discharged in time. Compared with other carbon steel elbows, aluminum alloy elbows of super pipes have some advantages, such as light weight and easy installation and use. Good corrosion resistance and scene resistance: aluminum and aluminum alloy flanges can produce hard and dense oxide films on the surface of our country, and many substances do not degrade them.

Super pipe manufacturers began to use 3D design software to design air conditioning and refrigeration systems. With its vivid interactive interface, highly parameterized design concept and intelligent analysis ability, 3D software has got rid of the shortcomings of the previous two-dimensional design, such as dullness, weak sense of entity and space, and has provided the possibility for efficient and high-quality development. Due to the high generalization and standardization of the parts and components of the super pipeline, and the similar appearance of the compressor, if the parameters of the pipeline are modified, the new four-way valve parts can be preliminarily constructed soon, which greatly reduces the time for the pipeline parts conception and design in the early stage.
