  Stainless steel tee plays a very important role in the pipeline. However, the stainless steel tee will inevitably rust due to its long service life. After rusting, it will not only damage the pipeline, but also cause leakage and serious problems. Great economic loss, so the stainless steel tee should pay attention to rust.

     paying attention to the corrosion protection of stainless steel tee can also prolong its service life. However, the anti-corrosion practice of stainless steel tee in different areas is not the same. In the south of China, the air is humid, which is the chemical hydrogen evolution corrosion. Water is one of the substances that make iron easy to rust, only when oxygen in the air dissolves. In water, oxygen reacts with iron in the water environment to produce something called iron oxide, which is rust. Rust is a brownish red substance. It's not as hard as iron. It's easy to fall off. When a piece of iron is completely rusted, its volume can expand by 8 times. If not derusting, spongy rust is especially easy to absorb moisture, which will accelerate the corrosion of stainless steel tee. Therefore, in the south of China, due to the influence of humid climate, the corrosion protection of stainless steel tee must adopt heavy corrosion protection.

     for stainless steel tee, if the corrosion of the pipe is thick, it should be knocked with a hammer first to make the rust layer fall off. When the rust layer is not thick, wipe the surface with wire brush, steel wire cloth or coarse sand cloth until the original color of the pipe is exposed, and then wipe it with cotton head. This method is only suitable for sporadic and scattered rusting, not suitable for large-scale use.

  Sand blasting is an advanced method in chemical pipeline anti-corrosion. This method can not only remove the rust layer, old paint layer and other dirt on the surface of steel pipe, but also form uniform small pits on the surface of steel pipe. This can increase the adhesion between the anticorrosive coating and the metal pipeline, improve the anticorrosion effect and service life of the coating, and pave the way for the next step.

     the stainless steel tee buried in the ground is generally subject to chemical pickling, which can remove rust and old coating. However, it should be noted that although chemical pickling can clean the surface of stainless steel tee, its anchoring method is shallow and easy to cause environmental pollution. Therefore, chemical cleaning is generally not recommended. Therefore, the corrosion-resistant stainless steel tee came into being. It is not only not easy to rust, but also strong and beautiful, which is very popular in the market.
