ERW stands for “electric resistance welded”. ERW pipes and tubes are manufactured by rolling metal and then welding it longitudinally across its length. ERW pipes have a welded joint in their cross-section. It is manufactured from Strip/Coil and can be manufactured up to 24” OD. High-frequency Induction Welding Technology is used for ERW Pipes &Tubes up to 21 inches OD. ERW pipe cold formed from a ribbon of steel pulled through a series of rollers and formed into a tube which is fused through an electric charge. It is mainly used for low/ medium pressure applications such as the transportation of water /oil.
Common sizes for ERW Steel Pipe and tubes are made in a variety of lengths to over 100 feet. Surface finishes are available in bare and coated formats and processing can be handled on-site to customer specifications.
MS stands for “Mild Steel.” And so, MS Pipes are made from mild steel they can easily be welded and formed in various shapes and sizes for pipelining and tubing purposes. These are generally used for drinking water supply i.e. Plumbing, Firefighting, and HVAC but can also be used in various other Industrial and Engineering applications.
Mild steel pipe refers to the content of less than 0.25% carbon steel because of its low strength, low hardness, and softness. MS pipes or tubes contain a small amount of carbon (0.18% or less) steel.
Mild Steel Pipe and MS Tubes conforming to IS:1239 Part I (1/2” to 6” NB – A-Class, B Class OR C Class) large-diameter Mild Steel Pipes confirming to IS:3589 Grade FE 330 or GR FE 410 (up to 20″, 508mm as per required wall thickness.)
