Surface treatment of ST44 pipe is one of the key factors to determine the service life of pipeline corrosion protection. It is the precondition for the combination of corrosion protection layer and steel pipe.Long-distance oil and gas pipeline is an important way of energy guarantee. It has a wide range of applications in anticorrosion construction of oil and gas pipeline. Here you will find out how ST44 pipe can be maintained and its application fields.

1. Cleaning of ST44 pipe

Clean the steel surface with solvents and emulsions to remove oil.But it can not remove rust, scale, flux, etc. on the surface of ST44 pipe, so it plays an auxiliary role in the production of corrosion protection.

2. Tool rust removal of ST44 pipe

The surface of ST44 pipe is mainly polished with wire brush and other tools to remove loose or cocked scale, rust, welding slag, etc.If the surface of ST44 pipe is firmly adhered to iron oxide scales, the rust removal effect of the tools is not ideal, and the depth of anchor grain can not meet the requirements of anticorrosion construction.

3. Pickling of ST44 pipe

Generally, acid cleaning of ST44 pipe is carried out by chemical and electrolytic methods, sometimes it can be used as re-treatment after sand blasting and rust removal.Pipeline corrosion protection only uses chemical acid pickling, which can remove scale, rust and old coatings. Although chemical cleaning can achieve a certain degree of cleanliness and roughness of the surface, it has shallow anchoring lines and is easy to cause environmental pollution.

ST44 pipe is widely used in piping, machinery industry, petroleum geological drilling, chemical industry, instrument and medical equipment.I hope this article can provide some reference and suggestions for your maintenance of ST44 pipe.
