At JPC, the quality control engineer and his team, inspect and test the raw materials, goods in process and the finished goods on daily basis. The following tests are conducted.
Name of the test | Methodology & Reasoning |
|---|---|
Inspection of surfaces & Edges | Visual Examination (By Normal or conrrected vision without magnification). |
Inspection of Marking | Brand name, Nominal size & country of origin on each length. |
Dimensional check | For maximum OD by GO Gauge & minimum OD by NO Go gauge to maintain standard size. |
Wall Thickness Measurements | Measured with the help of vernier callipers as specified in BIS standard (Accuracy equal to or more than 0.02 mm). |
Compression testing machine | By compressing the samples on compression test apparatus & calculating the percentage compression as maintained in BIS 9537 part I & II. To assures the mechanical strength of conduits. |
Bend test and ball test | By bending the sample on bend test apparatus & testing the samples for deformity & cracking of protective coating of original material. To check the ease of flow of the wire within the pipe |
Screw Thread Test | Length of the thread is measured by vernier & profile of thread by Go & NO Go gauge this ensures smooth jointing of pipes with each other. |
External influence (protective coating) | With the help of chemical as prescribed in BIS : 9537 Specifications medium and high protective coating of rigid steel conduits are tested for adequate protection against external influences. |
Durability of Marking | By rubbing process |
