Product Applications:
Hangao pipe surface finisher is probably the most important piece of equipment that enables the operator to finish the inner surfaces of metal pipes, such as long round pipes, accurately and smoothly. Its application has been found to be effective in those sectors of the industry where extremely smooth, clean, and low-roughness surfaces are necessary:
1. Fluid Transportation Industry:
Food and Pharmaceutical: Stainless steel pipes, dairy pipes, beer pipes, etc. Provide a smooth, angle-free inner wall, which is easy to clean and prevents bacterial growth, thereby complying with sanitary standards.
Chemical and Energy: Oil, natural gas, chemical media, transportation pipelines. The inner wall smoothness is improved to lower the flow resistance. It also prevents scaling and the adhesion of the medium, and thus enhances the efficiency and safety of the transportation.
Water Treatment: Pipes for drinking water, high-pressure water pipes, boiler tubes. Helps prevent the formation of scale and maintains water quality.
2. Precision Instruments and Transmission Industry:
Hydraulic and Pneumatic Systems: Hydraulic cylinder tubes, pneumatic cylinder tubes, and accumulator tubes. It is very important that the inner wall of these tubes should be very smooth in order to ensure the life of the seals, to minimize the friction and wear, and also to prevent the system from being contaminated as well as leakage.
Automotive Industry: Shock absorber tubes, steering gear tubes, fuel lines, etc.
Aerospace: Various high-precision, high-strength aviation piping systems.
3. Decoration and Specialty Industries:
Furniture and Decoration: Stainless steel handrails, flagpoles, and exhibition tubing are some of the ways to aesthetically upgrade and additionally increase the anti-corrosive property of the inner walls.
Semiconductor and High-Purity Gases: Special stainless steel or aluminum alloy pipes that require ultra-mirror polishing to completely get rid of gas adsorption and particle shedding.
