Product Description
ASTM A978 Plastic Coated Steel Pipe: Pre-Coated Polyethylene Lined Composite Rib Welded Steel Pipe
Material
ASTM A978 specifies the requirements for plastic-coated steel pipes, particularly those that are pre-coated with polyethylene. This composite rib welded steel pipe is designed to provide enhanced durability and corrosion resistance, making it suitable for various applications in harsh environments.
Specification
The ASTM A978 standard outlines the specifications for the manufacturing process, dimensions, and performance characteristics of plastic-coated steel pipes. The pipes must meet specific criteria for coating thickness, adhesion, and overall structural integrity.
Key Features
- Corrosion Resistance: The polyethylene coating provides excellent protection against corrosion, extending the lifespan of the pipe.
- Durability: The composite rib design enhances the mechanical strength of the pipe, making it suitable for high-pressure applications.
- Lightweight: Compared to traditional steel pipes, the plastic-coated variant is lighter, facilitating easier handling and installation.
- Versatility: Suitable for various applications, including water distribution, sewage systems, and industrial uses.
Chemical Composition
| Element | Composition (%) |
|---|---|
| Carbon (C) | 0.05 - 0.25 |
| Manganese (Mn) | 0.30 - 0.60 |
| Phosphorus (P) | ≤ 0.04 |
| Sulfur (S) | ≤ 0.05 |
| Silicon (Si) | 0.10 - 0.40 |
| Iron (Fe) | Balance |
Mechanical Properties
| Property | Value |
|---|---|
| Yield Strength (min) | 250 MPa |
| Tensile Strength (min) | 400 MPa |
| Elongation | 20% (min) |
| Hardness | 120 HB (max) |
Steel Grade
The steel grade used in ASTM A978 pipes typically falls under the standard structural steel grades, such as ASTM A53 or ASTM A106, depending on the specific application and requirements.
Application
ASTM A978 plastic-coated steel pipes are widely used in:
- Water and Wastewater Systems: For transporting potable water and sewage.
- Industrial Applications: In chemical processing and manufacturing.
- Agricultural Irrigation: For efficient water distribution in farming.
Possible Alternative Grades
While ASTM A978 is a preferred choice for many applications, alternative grades may include:
- ASTM A53: Standard specification for pipe, suitable for welding and bending.
- ASTM A106: Seamless carbon steel pipe for high-temperature service.
- ASTM A795: Standard specification for black and hot-dipped galvanized welded and seamless steel pipe for fire protection use.
