The quality management system of USKFL has been certified as per ISO 9001:2008. These formal quality frameworks help us monitor and improve quality by managing daily work through "Procedures" and "Work Instructions".

Our team follows the set procedure - from raw material purchase to pre-shipment inspection. Adhering to the principle of quality control, USKFL maintains full traceability of all its products. Each piece is permanently marked with logo/brand name, standard code, size, material number and heat number.

The quality management system helps us to succeed through improved customer satisfaction, staff motivation and continual improvement.

Inspection Team & Equipments

Experienced inspection team of USKFL conducts entire quality control procedure for each order, in all our factories. All inspectors are well trained and have rich product knowledge & inspection experiences.

In order to make the inspection result more dependable, various Non-Destructive Testing (NDT) methods are used, such as:

  • Visual Inspection

  • Dimension Checking

  • Chemical Analysis

  • Hardness Test

    For some of the tests which can't be conducted in our labs, we have approved labs for further testing. After inspection, the senior engineer issues a release note for shipment. Detailed inspection reports are put on file for tracing and Mill test Certificate are released to customers





Organization: We have a quality control department handled by a team of Q.C. experts whose work is to maintain all the records & supervision of Q.C. Inspectors.

Processing System: While selecting raw material we carry out a physical and chemical test. After acceptance of it, a control number is issued which is marked on the material. At the time of forging and forming of flanges, fittings etc same control number is transferred to further operation. After final forging or heat treatment a batch number is allocated a lot and this batch number is stamped on each pipelining component.

Machining: After final heat treatment process, all the pipelining components are sent for machining that includes O/D and I/D matching as per dimensional codes. An expert quality control engineer keeps constant vigil on every machining operation. All the machining is carried out as required by the standard.

Testing: In this step, three types of testing are performed: Tensile testing, Hardness tests and Impact testing. In tensile testing, sample is taken from the pipelining components in accordance with codes as required by purchaser on universal testing machine calibrated & approved by the authorized inspection agencies. In hardness testing, results are recorded in separate register and it is performed on at least 10% of whole lot. Impact testing is carried out on low temperature fittings covered by specification ASTM A420 WPL grades.

Marking: After the final dimensional check each fitting is marked for size, schedule, fitting specification, heat mark & batch number.

Certificate: All of our pipeline components supplied to the purchaser are furnished with manufacturer's test certificate which includes data i.e. raw material composition, heat treatment done, heat mark, batch number, hardness value, chemical & physical test results, radiography results, size, schedule, specification and quantity supplied.
