South Korea's Sanshan oxygen acetylene pipe is the best because it is 1. Aging resistant. The material of Sanshan hose is PVC plus a small amount of LG rubber. Compared with traditional rubber pipes, it has obvious aging resistance. It will not crack evenly on the surface after being used outdoors for more than five years, while rubber pipes usually crack evenly in one to two years. 2. Oil resistant. The PVC material itself determines the product's oil resistance. 3. High pressure resistance. The working pressure is 30KG and the burst pressure is 120KG, which far exceeds the working pressure required by the auto maintenance industry. With a high burst pressure, it can protect the auto maintenance industry from accidental crushing of vehicles or heavy objects during operations, effectively avoiding damage to pipes. Traditional rubber pipes have low pressure and will burst when rolled; steel wire pipes used for air cannons will be flattened when rolled, causing the internal steel wires to deform, resulting in air leakage or damage to the air pipe. 4. Soft in all seasons. A cold-resistant agent is added to the material to give the pipe good weather resistance. It is not soft in summer and not hard in winter. It is easy to retract and unfold when working. 5. Good wear resistance. The material and structure of the pipe determine that the pipe can effectively reduce wear during use. PVC material itself has better wear resistance than rubber; the pipe adopts polyester thread braiding and bonding process, which makes the pipe itself very light, about 30% lighter than rubber pipe. It is about 50% lighter than the steel wire pipe used in the wind cannon. Light weight means less wear and tear. 6. Light weight. Reduce the level of fatigue during work and also reduce wear and tear. 7. Patented products, with high technological content and new technology. The outer skin is matt and has a rubber feel, and all have anti-explosion holes, so there will be no bulges. The thread and the inner and outer skin are bonded using high-temperature fusion instead of glue, so there will be no delamination. The braided structure is less affected by temperature changes. Fold the product, tie it in a knot, and tug it hard, and the product will still perform well after you release it. 8. Practical use has proven that the service life of this pipe is more than five times that of ordinary rubber pipes.
