What if a defective strip is utilized in the production of an ERW pipe?

If you opt for ERW pipes made by Mcneil Instrument, a reputable stainless steel welded pipe manufacturer in India, you can mitigate the risk of using defective strips in the production process. Electric resistance welding (ERW) involves shaping a strip of stainless steel into a pipe and then welding its ends by passing an electric current through them.

However, if a defective strip is used, the resulting pipe may suffer from issues such as uneven wall thickness or improper joint alignment, leading to heightened absolute roughness and potential leakages. Mcneil Instrument ensures the careful storage and transportation of strips to prevent such defects, thereby maintaining the quality and integrity of their products. Additionally, by purchasing SS 304/316 ERW pipes from Mcneil Instrument, customers receive assurance through meticulous material inspection and the provision of Mill Test Certificates, further guaranteeing the pipes’ adherence to stringent quality standards.
