Steel and Iron - Steel tubes used for water-wells (upto 200 mm dia)
Summry
Steel tubes for water wells (up to 200 mm dia) are cylindrical hollow sections manufactured from mild steel or carbon steel, designed to transport water from underground wells. They are durable, corrosion-resistant, and able to withstand pressure and soil conditions, making them suitable for irrigation, drinking water supply, and agricultural applications.
Why BIS Certificate is Mandatory for Steel tubes used for water-wells (up to 200 mm dia)
BIS certification is mandatory for steel tubes used in water wells to ensure compliance with Indian Standards for chemical composition, dimensional accuracy, tensile strength, and corrosion resistance. Certification prevents the use of substandard tubes, ensures water safety, supports long-term durability, and protects public health in water supply and irrigation systems.
What is BIS Certified for Steel tubes used for water-wells (up to 200 mm dia)
BIS certified specification for steel tubes for water wells (up to 200 mm dia) defines requirements for chemical composition, wall thickness, mechanical strength, surface quality, testing methods, and tolerances. Compliance ensures the tubes are safe, durable, and suitable for water transportation, resisting corrosion and pressure while maintaining dimensional accuracy.
