Aluminum alloy tubes are used for irrigation purposes to transport water from one place to another efficiently. These tubes are welded and should be strong, lightweight, and corrosion-resistant to increase their lifespan.
The tubes must follow up with the IS: 7092 (Part 1): 1992 standard, which includes their composition, strength, and size. BIS certification is required to check the tubes and their manufacturing process to ensure that they meet the standard requirements.
Overview of IS 7092 (Part 1): 1992
This standard defines the requirements for welded aluminum alloy irrigation tubes. It defines the key parameters to ensure quality and appropriate use.
- Chemical Composition: Ensures the right alloy is mixed for strength and durability
- Mechanical Properties: Checks the strength and ability to handle pressure
- Dimensions and Tolerances: Ensures proper size and fit with irrigation systems
- Surface Finish: Protects tubes from damage and environmental effects
Meeting these parameters is crucial for obtaining ISI Certification for Aluminium Alloy welded Tubes for Irrigation Purposes and ensuring reliable performance in irrigation systems.
testing and inspection requirements
To maintain the quality and reliability of aluminium alloy welded tubes, IS 7092 (Part 1): 1992 defines specific testing and inspection practices. These checks are carried out at different stages of production to ensure that every tube meets the required standards.
workmanship & surface finish
Tubes must be free from defects such as cracks, dents, or rough surfaces. Continuous inspection during manufacturing ensures a smooth finish and consistent quality throughout production.
chemical composition check
The chemical composition is verified to ensure the correct aluminium alloy is used. This testing is carried out for each raw material batch (heat). It may be conducted at BIS-approved laboratories (S), and if the raw material is already ISI marked, re-testing may not be required.
mechanical strength test
To ensure durability and performance, the following tests are conducted on each production batch (control unit):
- Tensile Strength Test: Checks the strength of the tube
- Flattening Test: Ensures the tube can withstand deformation without cracking
Both tests are required to be performed within the factory (R).
hydrostatic pressure test
This test verifies the tube’s ability to withstand internal pressure without leakage. It is conducted on every single tube, making it one of the most critical safety checks. This test must be performed in the factory (R).
dimensions & tolerances
The diameter, thickness, and overall size of the tubes are checked regularly during production. Continuous monitoring ensures proper fitting and compatibility in irrigation systems.
in-house testing requirements
Some tests must be conducted within the factory, while others can be performed at BIS-approved laboratories:
- R (Required): Test must be done in-house
- S (Subcontracting Allowed): Test can be outsourced
Importance of These Checks
These inspection and testing practices help in:
- Maintaining consistent product quality
- Reducing defects during production
- Ensuring compliance with BIS standards
- Allowing only approved products to carry the ISI mark
bis certification process for aluminium alloy tubes for irrigation purposes(welded tubes)
The process of getting BIS certification involves various steps that are taken to ensure that these tubes are manufactured as per the Indian Standard. These steps are as follows:
- Online Registration: The first step in getting BIS certification is to register on the Manak portal, BIS’s online platform. Manufacturers need to create an account, fill in company details, and provide information about the product and manufacturing process. They also have to upload supporting documents like technical specifications and test reports. For foreign manufacturers, a hard copy of the application and documents must be sent to the BIS office, and an Authorized Indian Representative (AIR) should be appointed to handle communications.
- Testing at BIS-Approved Laboratory: The next step is to conduct testing on samples of Aluminium Alloy Tubes at a laboratory that has been approved by the BIS.
- Application Submission: The application along with test reports, supporting documents, and KYC needs to be sent to the BIS. In addition to this, a nomination process needs to be done for foreign manufacturers, along with sending an official communication.
- Factory Inspection: The officials from BIS inspect the manufacturing unit to check:
- Manufacturing process
- Raw material details
- Factory layout
- In-house testing facilities
- Quality control measures
- Grant of BIS License: After successful verification of documents and test reports, the license is issued by BIS. In the case of foreign manufacturers, the confidential test report is sent to the Foreign Manufacturers Certification Department. After verification, the license is granted.
