The production of anti-corrosion and thermal insulation steel pipes needs to be produced according to national standards. Different processing methods follow different standards, but they must meet the national production standards and must be strictly followed and implemented. At present, the processing types of anti-corrosion thermal insulation steel pipes are as follows, which need to be set and selected according to different situations. The processing types of anti-corrosion thermal insulation steel pipes are described below:

1. Three-layer polyethylene anti-corrosion thermal insulation steel pipe and steel pipe anti-corrosion for oil and natural gas. In the process of transporting natural gas, it is necessary to use a three-layer or two-layer polyethylene thermal insulation steel pipe. The use of this form of steel pipe can ensure the safety and effectiveness of transportation, and ensure that the steel pipe is not corroded or damaged. The executive standard of this kind of anti-corrosion and heat preservation steel pipe is SY/T0413-2002DIN30670. During the processing and production, it is necessary to strictly follow this standard to ensure the smooth progress of the work and the quality of the product.

2. FBE (single-layer sintered epoxy powder anti-corrosion) anti-corrosion thermal insulation steel pipe and anti-corrosion thermal insulation steel pipe for petroleum. Different transported substances may require steel pipes of different materials to be transported to ensure the safety and reliability of the transported substances. FBE anti-corrosion thermal insulation steel pipe and 2FBE anti-corrosion thermal insulation steel pipe have the same production standards. The production and processing standards are SY/T0315-97 and SY/T0315-2005.

3. The water supply pipeline is lined with cement mortar to prevent corrosion inside the steel pipe. This kind of anti-corrosion and heat preservation steel pipe needs to be used in the transportation of cement mortar in the water supply pipeline. This steel pipe can effectively block the cement sand in the pipe and reduce the resistance during transportation. The production standard of this kind of anti-corrosion and thermal insulation steel pipe is CECS10:89.

4. Epoxy coal tar glass cloth anti-corrosion and thermal insulation steel pipe. This kind of anti-corrosion and thermal insulation steel pipe is mainly to effectively prevent the corrosion of asphalt and prevent the asphalt from damaging the steel pipe to a certain extent. The production standard is: GB50268-97SY/T0447-96.
