ERW stands for high frequency electric resistance welding, which is a welded steel pipe made by electric welding process.
What is ERW Pipe?
ERW uses high-frequency current welding, which has more precise dimensional control than seamless steel pipes, high efficiency and low cost. It is mainly used to transport liquid media such as water, oil, and natural gas. There are many standards such as GB/T 3091, GB/T 9711-2017, API 5L, API 5CT, ASTM A53, and EN10219.
