BIS Certification Consultancy for Stainless Steel Welded Pipes & Tubes | IS 17876:2022

Introduction

Stainless steel welded pipes and tubes are widely used in general-service applications because of their corrosion resistance, strength, durability and suitability for demanding industrial environments. They are used across sectors such as engineering, chemical processing, food processing, pharmaceutical equipment, construction, utilities, fabrication and industrial piping.

Because welded stainless steel pipes and tubes can be exposed to pressure, temperature, mechanical stress and corrosive environments, consistent chemical composition, mechanical properties, weld quality, dimensions, leak tightness and surface condition are important.

The applicable Indian Standard is IS 17876:2022 – Stainless Steel Welded Pipes and Tubes for General Services. The BIS Product Manual PM/IS 17876/1, August 2022 provides the certification framework under Scheme-I, including product grouping, sampling, testing equipment, inspection and testing controls and marking requirements. (bis.gov.in)

The standard is currently listed by BIS as a mandatory certification product. The current Stainless Steel Pipes and Tubes (Quality Control) Order, 2025 covers IS 17876:2022 and specifies implementation from 1 August 2025. (standards.bis.gov.in; bis.gov.in)

Qualitance India provides complete BIS Certification consultancy for Stainless Steel Welded Pipes & Tubes, covering standard applicability, product scope, grouping, sample planning, testing coordination, documentation, factory inspection preparation, BIS application filing, licence processing and post-licence compliance.
