Yuxin anti-corrosion welded steel pipe base materials include straight seam steel pipes and spiral steel pipes. Inner wall anti-corrosion coating: a thin film coated on the inner wall of the pipe in order to prevent corrosion within the pipe, reduce frictional resistance, and increase output.
Commonly used coatings include amine-cured epoxy resin and polyamide epoxy resin. Anti-corrosion and thermal insulation coating: On medium and small diameter heat transfer crude oil or fuel oil pipelines, in order to reduce the heat dissipation of the pipeline to the soil, a composite layer of insulation and anti-corrosion is added to the outside of the pipeline. The commonly used insulation material is rigid polyurethane foam. If the outer protective pipe is a polyethylene pipe, no anti-corrosion is required. Implementation standards: Technical standards for polyethylene anti-corrosion layers of buried steel pipelines. Technical standards for polyethylene anti-corrosion layers of buried steel pipelines. It is suitable for pipe networks such as coal mine underground water supply and drainage, underground grouting, positive and negative pressure ventilation, gas drainage, fire sprinkler and other pipe networks. Thermal power plant process water waste residue and return water transportation pipelines. It has excellent applicability for water supply pipelines in anti-sprinkler and sprinkler systems. Cable protection sleeves for power, communications, highways, etc. It is suitable for pipelines such as water supply in high-rise buildings, heating network heating, tap water projects, gas transmission, and underground water transmission. Process pipelines for transporting corrosive media in petroleum transportation pipelines, chemical pharmaceuticals, printing and dyeing and other industries. Sewage treatment discharge pipes, sewage pipes and biological pool anti-corrosion projects. Agricultural irrigation pipes, deep well pipes, drainage pipes and other networks, etc.
