What are the model types and specifications for plastic-coated pipe?

In recent years, the building materials market has seen a surge in new steel pipe materials, which are significantly different from the commonly used piping materials of the past. Initially, people were unaware of any major performance differences, but they did notice considerable differences in appearance, which can also be attributed to structural differences. These new steel materials are known as plastic-lined pipes, and they have not only gained a vast range of applications but have also amassed a significant number of "loyal fans." Moreover, the variety is extensive. So, what are the classifications and specifications of these pipes?

The classification standards and model specifications for the plastic-coated pipes are as follows.

Category:

1. By coating type: Internal coating and internal-external coating composite plastic-lined pipes.

2. The pipes are categorized based on the different inner coating materials: Epoxy Coated Steel Pipes, Polyethylene Coated Steel Pipes, Inner Epoxy and Outer Three-Layer Polyethylene Steel Pipes, and Inner Epoxy and Outer Polyethylene Steel Pipes.

Model and Specifications.

The product model is composed of the product code, coating material code, coating form, nominal bore size, base tube category, etc.

1. Category: Welded Steel Pipe, H; Seamless Steel Pipe, W.

2. Nominal Bore (mm).

3. Coating Form: Both interior and exterior coating, D; Interior Coating: Omitted and not marked.

4. Interior Coating Material Code: Epoxy Resin, EP.

In summary, plastic-coated piping currently enjoys a wide range of applications, meaning it diligently contributes to the construction industry without seeking recognition. In fact, the development of steel pipe materials in our country in the past was particularly impressive, and it has made significant contributions and efforts to the growth of the construction sector. However, as China is vigorously promoting the construction of green, healthy, and environmentally-friendly cities, the use of eco-friendly piping materials, such as plastic-coated piping, has become prevalent.
