ASTM A53 GR B ERW PIPE (Electric Resistance Welded PIPE, resistor welding pipe) is a steel pipe produced according to the standard of ASTM A53/A53M, where “GR B” refers to the level of the steel pipe.
ASTM A53 GR B ERW tube meets the following standards:
ASTM A53/A53M: It is suitable for the standard specifications of seamless and welded black and hot -dip galvanized steel pipes, which are suitable for ordinary use.
ASTM A53 GR B ERW Pipe is produced by resistance welding. Resistance welding is a method of pressing the workpiece between two electrodes and passing an electric current through the contact surface and adjacent areas of the workpiece to heat it to a molten or plastic state to form a metal bond.
ASTM A53 GR B ERW pipe has a variety of sizes and specifications. Common sizes include:
Outer diameter (OD): 1/8 inch to 26 inches (about 10.3mm to 660.4mm)
Wall thickness: SCH 10 to SCH 160, XXS, etc.
Length: It can be customized according to customer needs, usually 6 meters or 12 meters.
Features of ASTM A53 GR B ERW pipe:
Excellent strength and durability: Suitable for fluid transportation at medium pressure and temperature.
Easy processing: It can be cut, bent and welded.
Surface treatment: The pipe can be galvanized, painted and other surface treatments to improve corrosion resistance.
ASTM A53 GR B ERW tube is made of carbon steel, and its chemical composition is as follows:
Carbon (C): maximum 0.3%
Manganese (mn): 1.2%
Phosphor (P): maximum 0.05%
Sulfur (S): maximum 0.045%
Copper (CU): Maximum 0.4%
Nickel (ni): maximum 0.4%
Chromium (CR): maximum 0.4%
Molybdenum (MO): maximum 0.15%
0 (V): maximum 0.08%
ASTM A53 GR B ERW tube has the following mechanical properties:
Tensile Stringth:
Minimum value: 415 MPa
Yield stream:
Minimum value: 240 MPa
Elongation:
Minimum value: 20%(at a 2 -inch or 50.8mm marked distance)
ASTM A53 GR B ERW tube is widely used in the following fields:
Fluid transportation: suitable for transportation of fluids such as water, oil, and natural gas.
Architecture and structure: for architectural structure, bridge, steel structure, etc.
Machinery manufacturing: used for manufacturing machinery parts and equipment.
Infrastructure construction: used for pipeline systems such as water supply, gas supply, heating, etc.
Shipbuilding steel plate refers to the carbon and alloy steel plate used in offshore and marine contructions, common grades are A, B, D, E, AH32/36/40,
316 stainless steel plate is a higher common use stainless steel than 304&304L, it has 2.0 to 3.0% of Molybdenum content which provides better overal
