Introduction
The BIS certification for Steel Drill Pipes, as per IS 19112:2025, is a significant quality assurance measure established by the Bureau of Indian Standards to ensure that drill pipes used in the petroleum and natural gas industry meet high safety and quality standards. Steel drill pipes are a critical component in drilling processes, where they are subjected to high pressure, stress, and environmental conditions.This standard indicates the technical specifications for steel drill pipes, which include quality, mechanical strength, dimensions, and tests, etc. The certification of this product by BIS ensures that it complies with Indian standards, is safe, reliable, and suitable for use in the industry.
What is IS 19112:2025?
IS 19112:2025 is an Indian Standard for steel drill pipes for use in the petroleum and natural gas industries. The standard is developed by the Bureau of Indian Standards and is based on international standards such as ISO 11961 to maintain global standards for quality and performance of drill pipes.The IS 19112:2025 defines the technical specification and quality requirements that have to be adhered to by the manufacturers of steel drill pipes for better performance in drilling operations.
Key Points:
- It covers the processes involved in the manufacture of steel drill pipes, the raw materials used, and the chemical composition.
- It covers the mechanical properties of the steel drill pipes, including the tensile strength, yield strength, and toughness.
- It covers the dimensional requirements and tolerances.
- It covers the testing methods and inspection requirements.
- It ensures the steel drill pipes can withstand extreme pressure and stress.
Products Covered Under IS 19112 : 2025
IS 19112:2025 is the standard applicable to steel drill pipes used in oil and gas drilling operations. It is published by the Bureau of Indian Standards. It is applicable to steel drill pipes which experience extreme mechanical stresses, pressures, and environmental conditions.
Key Reasons:
- Steel Drill Pipes:These are primary tubular elements employed in the transmission of power and fluid to a drill bit in oil and gas exploration.
- Tool Joints:These are robust threaded connections attached to drill pipes. They guarantee robust and secure connections in a drill pipe.
- Upset Drill Pipes:These are drill pipes designed with thickened ends, either internal or external upset ends, to enhance durability.
- Plain-End Drill Pipes:These are drill pipes supplied without tool joints; they are employed in processing and customizing.
- Drill Pipe Accessories & Components:These include protectors, couplings, and other integral drill pipes components employed in conjunction with drill pipes.
