BIS Certification for Hot Rolled Steel Plate (up to 6 mm) Sheet and Strip for the Manufacture of Low Pressure Liquefiable Gas Cylinders IS 6240:2008

Hot Rolled Steel Plate (up to 6 mm), Sheet, and Strip are crucial materials in the manufacturing of low-pressure liquefiable gas cylinders. These steel products offer the necessary strength, durability, and malleability to withstand the pressure and conditions required for safely storing and transporting gases such as propane, butane, and LPG. Their consistent thickness and high-quality surface finish make them ideal for forming into the cylindrical shapes needed for gas cylinders. Additionally, the hot rolling process enhances the steel's mechanical properties, ensuring it can handle the stresses and strains involved in gas storage and transportation applications, thereby ensuring safety and reliability.

Importance of BIS Certification

BIS certification is essential for Hot Rolled Steel Plate (up to 6 mm), Sheet, and Strip used in the manufacture of low-pressure liquefiable gas cylinders to ensure they meet the stringent quality and safety standards set by the Bureau of Indian Standards. This certification guarantees that the steel products possess the necessary mechanical properties, such as tensile strength, ductility, and impact resistance, which are critical for the safe storage and transportation of gases. Adhering to BIS standards ensures the reliability, consistency, and safety of the gas cylinders, preventing potential failures that could lead to hazardous leaks or explosions. Certification also promotes consumer confidence, ensures regulatory compliance, and supports manufacturers by providing assurance of high-quality materials essential for producing safe and effective gas cylinders.

Indian Standard IS 6240:2008

As per the latest Quality Control Order (QCO) issued by the Ministry of Steel, Government of India on 5th February 2024, Hot Rolled Steel Plate (up to 6 mm) Sheet and Strip for the Manufacture of Low Pressure Liquefiable Gas Cylinders must conform to the Indian Standard IS 6240:2008. This standard specifies the essential requirements for hot rolled steel plates, sheets, and strips used in the manufacture of low-pressure liquefiable gas cylinders. Compliance with IS 6240:2008 ensures that these materials meet critical quality criteria such as mechanical properties, dimensional tolerances, and surface finish, ensuring their suitability and safety in the production of gas cylinders intended for storing liquefiable gases under low pressure conditions. Adhering to this standard is crucial for manufacturers to ensure regulatory compliance, maintain product integrity, and uphold safety standards in the handling and storage of liquefiable gases.
