IS 3589 is a standard developed by the Bureau of Indian Standards (BIS) for steel pipes and pipe fittings used for water, gas and air transportation. It is usually applicable to welded steel pipe or seamless steel pipe, including mild steel pipe.
Scope of application of the standard
1. Applicable products
IS 3589 is mainly for mild steel pipes and related pipe fittings,
suitable for water, gas and air transportation systems.
2. Uses
The mild steel pipes specified in this standard are widely used in
civil and industrial fields, such as urban water supply systems, gas
transmission networks and ventilation systems.
Main requirements of the standard
1. Dimensions and tolerances
The standard specifies in detail the dimensional requirements of mild
steel pipes such as outer diameter, wall thickness and length, and clearly
defines the tolerances in production to ensure the consistency and
interchangeability of products.
2. Material composition
IS 3589 has strict requirements on the chemical composition of mild
steel pipes to ensure that the raw materials and finished steel pipes have
corrosion resistance and mechanical properties that meet the requirements of
use.
3. Mechanical properties
Including requirements for performance indicators such as tensile
strength, yield strength, and elongation, these properties ensure that the
pipeline will not fail when subjected to working pressure and external impact.
4. Test methods and inspection standards
The standard specifies the specific methods and inspection procedures
for physical and chemical performance tests on mild steel pipes to ensure that
each batch of products meets the specified standard requirements.
Summary
In short, the IS 3589 standard provides detailed and strict technical
specifications for the manufacture and use of mild steel pipes, ensuring the
performance, safety and quality of pipeline products in actual applications.
