BIS Certification for Steel Tubes Used for Water-Wells | IS 4270:2001 | BIS Consultancy

Introduction

Steel tubes used for water-wells are important components in the construction of tube wells and groundwater extraction systems. These tubes can be used for applications such as casing pipes, drive pipes and housing arrangements, where adequate strength, dimensional accuracy, joint quality and durability are important.

IS 4270:2001 – Steel Tubes Used for Water Wells – Specification specifies requirements for steel tubes used in water-well applications. BIS has a dedicated Product Manual for certification under Scheme-I, which provides guidance on sampling, grouping, testing equipment, inspection and testing and the scope of certification.

BIS currently lists IS 4270:2001 – Steel tubes used for water-wells (up to 200 mm dia) under its compulsory product-certification framework.

Qualitance India provides BIS Certification Consultancy for manufacturers of steel tubes used for water-wells, supporting product assessment, documentation, testing coordination, BIS application and factory inspection preparation.

Product ke baare mein

Steel Tubes Used for Water-Wells are specially manufactured tubes used during the construction and installation of water wells.

Depending on the application, these tubes may serve as:

Casing pipes
Drive pipes
Housing pipes
Other water-well tube applications

They provide structural support to the well and help maintain the integrity of the borehole.

Water-well tubes need to withstand mechanical stresses arising from:

Surrounding soil
Water pressure
Installation operations
Handling
Well construction activities
Long-term service conditions

BIS's information on IS 4270:2001 identifies these tubes as components used for water-well construction, including casing pipe, screen-related applications and pump housing.

Applicable IS Standard

The applicable Indian Standard is:

IS 4270:2001 – Steel Tubes Used for Water Wells – Specification

The BIS Product Manual identifies IS 4270:2001 as the applicable standard for certification and provides certification-related requirements for manufacturers and prospective applicants.

The current BIS product-specific information page also lists IS 4270:2001 – Steel Tubes used for Water Wells – Specification among the available Product Manuals.
