EFW stainless steel pipes
EFW stainless steel pipes, also known as Electric Fusion Welded stainless steel pipes, are a type of pipe commonly used in various industries for their exceptional strength and corrosion resistance.
EFW stainless steel pipes offer several advantages over other types of pipes. Firstly, they have a high degree of durability and can withstand extreme temperatures and pressures, making them suitable for use in demanding environments such as chemical plants and oil refineries. Additionally, these pipes have excellent resistance to corrosion, ensuring longevity and minimizing the risk of leaks or pipe failure.
EFW (Electric Fusion Welding) pipes and tubes are widely used in various industries for their durability and strength. These pipes and tubes are manufactured using the electric fusion welding process, which involves applying heat to the edges of the steel plates or coils until they reach a plastic state. The edges are then forced together under pressure to create a solid weld.

Alloy steel pipe introduction
Alloy steel pipe is mainly used for high-pressure and high-temperature pipelines and equipment such as power plants, nuclear power plants, high-pressure boilers, high-temperature superheaters and reheaters. It is made of high-quality carbon steel, alloy structural steel and stainless heat-resistant steel. , by hot rolling (extrusion, expansion) or cold rolling (pulling).
The biggest advantage of alloy steel pipes is that they can be 100% recycled, which meets the requirements of environmental protection, energy saving, and resource conservation. Alloy pipes and seamless pipes are both related and different, and should not be confused with each other.

Alloy Tube Standard
Alloy pipe characteristics:
The performance of the alloy pipe is much higher than that of the general seamless steel pipe, because this kind of steel pipe contains more Cr, and its high temperature resistance, low temperature resistance, and corrosion resistance are better than other seamless steel pipes. They are both related and different, and should not be confused with each other.

304 stainless steel welded pipe standard
304 stainless steel welded pipe represents the difference between 301, 302, 303, 304L, and 304H. The nickel-based stainless steel with the best process performance and the best oxidation performance is the leader that should not be easily replaced.
304 stainless steel welded pipe is made of AISI304 stainless steel material, and a variety of steel pipe specifications are commonly used to meet different process requirements. According to the general requirements of welded pipes, ASTM A312 / A312M standard production is implemented, usually made of AISI304 material, which has excellent general performance and good corrosion resistance in the medium of normal temperature -15°C-201°C. According to customer requirements, we can provide 304 stainless steel welded pipe series products for precision and rough product mechanical properties and heat treatment requirements at higher ambient temperature.

Comparison of ASTMA790 and ASTMA928 standards for duplex steel pipes
Both standards are standard specifications for ferritic-ausic stainless steel tubing used in corrosive environments. ASTM A790 specifies the elements and requirements for the manufacture of seamless and welded pipes, while ASTM A928 covers only electric fusion welded pipes. ASTM A790 requires that duplex and super duplex steel pipes be welded without the addition of any filler metal. ASTM A928 requires that the weld be welded with the addition of filler metal.
