GB/T 28413 SA178 is a standard specification for high-frequency welded carbon steel pipes commonly used in boiler heat exchangers. This article provides an overview of the material, specification, key features, chemical composition, mechanical properties, steel grades, applications, and possible alternative grades for SA178 pipes.
The material used for GB/T 28413 SA178 pipes is carbon steel. Carbon steel is an alloy of iron and carbon, with small amounts of other elements. It is widely used in various industries due to its excellent strength, weldability, and affordability.
The specification of GB/T 28413 SA178 pipes includes the following parameters:
| Parameter | Specification |
|---|---|
| Outer Diameter | 10 mm to 168 mm |
| Wall Thickness | 2 mm to 20 mm |
| Length | 6 meters or as per customer's request |
The chemical composition of GB/T 28413 SA178 pipes typically includes the following elements:
| Element | Percentage Range |
|---|---|
| Carbon | 0.06%-0.18% |
| Manganese | 0.27%-0.63% |
| Phosphorus | 0.035% maximum |
| Sulfur | 0.035% maximum |
| Silicon | 0.10% maximum |
The mechanical properties of GB/T 28413 SA178 pipes are as follows:
| Property | Minimum Value |
|---|---|
| Tensile Strength | 325 MPa (min) |
| Yield Strength | 180 MPa (min) |
| Elongation | 35% (min) |
| Hardness (Rockwell) | HRB 72 (max) for Grade A |
| HRB 79 (max) for Grade C |
GB/T 28413 SA178 pipes are available in two steel grades: Grade A and Grade C. The steel grade determines the specific mechanical properties and suitability for different applications.
GB/T 28413 SA178 pipes find extensive usage in boiler heat exchangers, where they are used for conveying heated fluids. They are commonly employed in industrial settings such as power plants, chemical plants, and manufacturing facilities.
In addition to GB/T 28413 SA178, there are several alternative grades of carbon steel pipes available in the market. Some commonly used alternatives include ASTM A178 Grade A, ASTM A192, and DIN 17175 st35.8 pipes. These alternatives may have slightly different specifications and properties, so careful consideration is essential before selecting the appropriate grade for specific applications.
