What is ERW tube for fire fighting?
ERW tube for fire
fighting refers to steel pipe made by resistance welding and used in the fire
fighting field. Electric resistance welded pipe (ERW) is produced by the continuous processing of steel coils using resistance welding. The advantages of ERW tubes include high production efficiency, low cost, and affordable price. ERW steel tube is formed by rolling strip and welding, resulting in tighter dimensional tolerances and reduced weight.
Fire tubes refer to pipe materials used for fire fighting, connecting fire fighting equipment and systems, and transporting fire extinguishing water, gas or other media. Since fire protection pipelines are often in a static state, the requirements for the pipelines are strict. They need to withstand pressure, corrosion and high temperatures.
Advantages of ERW fire fighting pipes:
(1) Strength and durability
ERW tubes are made from high-quality steel for exceptional strength and durability. This is critical for fire
fighting systems as they need to withstand high pressures and temperature fluctuations.
(2) Precision engineering
ERW tube is precision manufactured to ensure uniform wall thickness and consistent dimensions. This helps maintain the integrity of the fire
fighting system and ensures reliable performance.
(3) Cost-effectiveness
ERW tube is cost-effective compared to seamless pipe or other types of
welded pipe. This makes them the first choice for fire protection applications, especially in projects with limited budgets.
(4) Availability and accessibility
ERW tubes come in a variety of sizes and specifications and can be easily used in fire protection projects. This ensures that installation and repairs are completed in a timely manner.
(5) Easy to install
ERW tube is lightweight and easy to handle, simplifying the installation process. This is advantageous for fire protection systems where quick and efficient installation is critical.
(6) Compatibility with paint
ERW tube can be easily coated with a fire-resistant coating to enhance its fire-resistant properties. This further increases their suitability for fire protection applications, ensuring maximum safety and protection. In addition, the surface can also be treated with fused epoxy (FBE), polyester resin, hot-dip galvanizing, red paint, black paint, etc.
Which specifications of ERW tubes are most suitable for fire fighting?
A variety of sizes and models of ERW (Electric Resistance Welded) steel pipe are ideal for fire protection applications, including:
(1) ASTM A53
Another commonly used ERW steel tube specification,
ASTM A53 covers seamless, welded black, and
hot-dip galvanized steel pipe. Suitable for fire protection systems, often used in fire sprinkler pipes.
(2) ASTM A135
This specification covers electric resistance welded steel pipe used for conveying gas, steam, water, or other liquids. It is widely used in fire protection systems due to its suitability for sprinkler systems and fire hydrants.
(3) BS 1387
This British Standard Specification applies to welded steel pipes suitable for threaded and socketed steel pipes and tubes, and for plain-ended steel pipes suitable for welding or screwing into BS 21 pipe threads. It is commonly used in fire protection applications.
(4) EN 10255
This European Standard specifies requirements for threaded and socket steel pipes and plain-ended steel pipes suitable for welding or screwing into BS 21 pipe threads. It is suitable for fire fighting systems.

Tips: ASTM A53 is the grade of ERW high-frequency welded pipe, which is divided into Grade A and Grade B. ASTM A53 Grade B is more popular than other grades. In case ASTM A53 Grade B in ERW (electric resistance welded) pipe, the weld seam of A53 erw pipe shall be done the heat treatment with a minimum 1000°F [540°C]. In this way the no untempered martensite remains.
In case ASTM A53 B pipe in cold expanded, then expansion should not exceed 1.5% of the required OD.
