We work closely with our customers to develop innovative products and applications.
  • Quality Policy: Scope:
    • This quality assurance program gives the scope to manufacture The Pipes, Tubes, Pipe fittings (Butt Weld & Forged), Flanges, Fasteners, Sheets, Plates, Wires, Tube Fittings, Etc. as per the National, International specification & dimensional standards.
  • Quality System:
    • A system comprises the way of Quality Control to be followed during the manufacturing process of Pipes, Tubes, Pipe Fittings, Flanges, Fasteners, Sheets, Plates, Wires, Tube Fittings, etc. so that an audit mechanism is introduced during manufacturing itself to produce a product meeting the requirements of desired codes & specifications.
  • Organization:
    • A separate quality control department is handled by a Q.C. an engineer who maintains all the records & supervises the Q.C. Inspectors.
  • Processing System:
    • At the raw material stage, the same is checked visually for any kind of surface defects such as cracks, seams, overlapping, pitting, as well as dimensionally. A chemical & physical test is carried out before selecting the Raw material. After acceptance of raw material, a control number is issued and this is punched/marked on the whole of the Raw material is to be used.
    • At the time of cutting, while manufacturing Fittings, Flanges, etc., the control number is transferred on each cut piece. The same is transferred after every operation of forging or forming in case of Invisibility of the same. After each forging or forming process, the material is checked visually for surface crack.
    • Here treatment is carried out after the final forging or forming as required by the code. After final forging or heat treatment, a batch number is assigned to a lot and this batch number is stamped on each pipe, Tubes, Fittings, Flanges, etc. and on the temperature chart which is automatically generated by temp. recorder coupled with the heating furnace. Time of final forging/forming & date is also mentioned on the chart.
  • Machining
    • After final forging/forming and Heat treatment process, all the Pipe Fittings, Flanges, Fasteners, etc. are sent for machining i.e. and preparation, O/D and I/D matching as per dimensional codes. An Expert Q.C. engineer is involved and he keeps a constant vigil on every machining operation. Step machining is carried out as required by the codes. GO and NO-GO gauges are used to check the O/D & I/D of the fittings, Flanges, etc.
  • Testing
    • The tensile test is done on a sample taken from mother Raw material or from the lots of Pipes, Tubes, Fittings, Flanges, Fasteners, etc. in accordance with codes as required by the purchaser on a universal testing machine which is calibrated & approved by the authorized inspection agencies.
    • Hardness testing is done on at least 10% of each lot & results are recorded in a separate register. The impact test is carried out on low-temperature fittings covered by specification ASTM A420 WPL grades.
    • 100% X-Ray examination is carried out on all Welded Pipes, Tubes, and Fittings.
  • Finishing:
    • All the Pipes, Tubes, Fittings, etc. are pickled and passivated. By pickling all the scale is removed which is formed during forging/ forming operations. After pickling, the grinding operation is done to remove the die mark and inside / outside burrs formed during forming & machining operation. Dimensional check is carried out finally & recorded.
  • Marking:
    • After the final dimensional check, each fitting is stamped /marked for size, schedule, fittings specification, heat mark and batch number.
  • Certificate:
    •  All the fittings supplied to the purchaser to the purchaser are furnished with Manufacturer’s test certificate. This certificate contains data i.e. Raw material composition, Heat treatment done, Heat Mark, Batch Number, Hardness value, Chemical & physical test results, Radiography results (If carried Out), size, schedule, specification and quantity supplied.
