Steel surface treatment is the key to determining pipeline corrosion, which is the premise of the close combination of coating and steel pipe and one of the key factors of service life. Its application research scope is also very wide in the anticorrosion construction management process of oil and gas pipelines. Long-distance oil and gas pipelines are an important way to ensure energy security.

Carbon steel pipes need anti-corrosion and anti-rust treatment. Carbon steel pipes are not stainless steel pipes and cannot be pickled and passivated. If the country is a new pipe, it can be scaled or coated with an anti-corrosion layer. If the pipe has been installed, you can ask a professional pipe repair company to deal with it. First remove the rust, and then apply a new anti-corrosion coating on the inner wall. This repair method does not need to disassemble the pipe, and can directly work in the original state of the pipe laying.

In addition, it depends on the specific requirements of the customer. Generally, anti-corrosion will only be done if this is required, but rust removal must be done before anti-corrosion. The rust removal method includes shot blasting (the highest yield, single and multiple root One can be cleaned in two minutes), pickling and derusting (environmental protection is very strict, so it is not used very much), and the low-level stage of manual derusting is probably not used by anyone and has been eliminated.

Application fields of carbon steel pipe:

1. Pipeline pipe
Such as: water, gas pipes, seamless steam pipes, oil pipelines, oil and gas pipelines. Agricultural irrigation water is used as tap water pipes and sprinkler irrigation pipes, etc.

2. Generally speaking, steel pipes, such as boiling water tube boilers, steam generating superheating tubes, small tubes, tube arch bricks, locomotive boiler superheater tubes, and thermal equipment leading to high temperature and high pressure boiler tubes.

3. Pipes for mechanical industry
Such as oil cooling controller tubes for tractors, square tubes and rectangular tubes for agricultural machinery, tubes for transformers, and tubes for bearings.

4. Pipes for petroleum geological drilling
Such as: oil drilling pipe, drill pipe, drill collar, tubing, casing and various joints, geological drilling pipe.

5. Steel pipes for chemical industry
Such as: petroleum cracking pipes, high-pressure pipe heat exchangers and pipes for chemical fertilizer equipment, chemical medium delivery pipes, etc.

The steel pipe is used to transport fluid and exchange heat and powder, and manufacture mechanical parts and containers, and what's more it's a kind of cost-effective steel.
