The term ERW in stainless steel vocabulary generally refers to a specific type of welding process. This kind of welding is one which involves both spot as well as seam welding. Typically, seam welding is a process which is commonly used during the manufacture of round, square or rectangular steel tubes.  On the other hand, the procedure to produce ERW stainless steel pipe dimensions would involve a flat stainless steel plate or sheet which is first rolled by being cold formed into the shape of a cylinder to become a pipe; followed by which, the cylindrical pipe is then welded using Electric Resistance Welding process longitudinally. Hence, the name ERW pipes. Usually, the ERW stainless steel pipe weight chart is used in the manufacture of pipes with a high diameter.

Both continuous welded stainless steel pipe dimensions as well as electric resistance welded pipe can be manufactured by shaping rolls of coiled steel into cylindrical forms and welding along the longitudinal seams of the pipes. There are several ways for the electric current which is to be used for welding the rolled strip or rolled pipe. One of these methods including a revolving copper disc, which is a fixed alloy Cu or copper contacts along with induction coils. Using this method ensures that the temperature of the steel edge has risen to about 2600 deg F, which is required for effective welding. The rolling process for the ERW stainless steel pipe exerts so much pressure that it tends to create a metal welded seam on the outside as well as on the inside of the pipe. However, these weld seams, which occur during this stage could be then removed during the finishing process of these stainless pipe sizes schedules . Following this treatment the ERW welded pipe will then be heat treated, inspected along with being hydro tested. Find out more about the ss pipe size chart here.

Usually, the ERW ss pipe sizes in mm is available in many of the following specs ASTM A53, A135, A252, A500, A795, API 5L and API 5CT. Although the most typically used specification for the construction of ERW specs would be both the A53 and the API 5L.

Electric Resistance Welded Pipes, otherwise known by their shorter variation i.e. ERW stainless steel pipes and tubes are used in various applications such as engineering purposes, fencing, scaffolding or in line pipes etc. At Siddhagiri Metals & Tubes, we manufacture various grades of ERW steel pipes and tubes.
