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.
null

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.
null

Organisation

A separate quality control department is handled by a Q.C. 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.

In Manufacturing Of Fittings, Flanges, etc. At the time of cutting, The control number is transferred on each cut pieces and 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 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 Pipes, 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, Fittings.

null

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, 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.
null

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.
null

Marking

After the final dimensional check, each fitting is stamped /marked for size, schedule, Fittings specification, Heat mark & batch number.
