Stainless steel thick-walled pipe is the most common form of thick-walled pipe. It has a wide range of applications in the industry. Because stainless steel thick wall has good pressure and corrosion resistance, it has become the most fashionable and most detectable material.
First, stainless steel thick-walled pipe features:
1. Stainless steel thick-walled pipe corrosion resistance: corrosion resistance is better than 304 stainless steel, and it has good corrosion resistance in the production process of pulp and paper. Moreover, 316L stainless steel is also resistant to erosion by marine and aggressive industrial atmospheres.
2, stainless steel thick-walled tube heat resistance: intermittent use below 1600 degrees and good oxidation resistance in continuous use below 1700 degrees
Second, stainless steel thick-walled tube classification
1. Stainless steel thick-walled pipe for mechanical construction and decoration

This stainless steel thick-walled product is used for piping of chemical, petrochemical, water treatment, papermaking, food hygiene and other equipment.
Film disc is one kind of velcro discs, using open sand planting method, planting the specially treated high-performance abrasive on the highly polyester film and carrying out special anti-blocking coating treatment, which can provide uniform grinding effect.
Film disc's advantage is the hidden super coated aluminum oxide corundum. The difference between it and other conventional coatings is that conventional discs have two layers of sanding surface. The outer layer on the sand paper falls down together with the sanding product's dust during sanding, which causing premature clogging.
However, film sanding disc has a hidden anti-clogging coating. This coating makes it last longer than all other traditional sand paper including the best 3M discs. Furthermore, the proprietary film backing causes a very strong bond between the abrasive and the film backing adding to its long life. Finally, the film backing and abrasive is very even, much more than conventional paper, making it much more effective during the entire sanding process.
Film discs are widely used in the grinding of automobile primer, atomic gray, intermediate paint and finish paint. And features: high grinding efficiency, good anti blocking performance, good grinding consisitency without secondary scratch, surface grinding GJ, durable.
