Kunshan facility is equipped with American GAGEMAKER precision length instruments and supporting ball gauges, thread gauges, depth sounder, digital calipers, micrometers and other dimension tooling; Kunshan and Ji’an laboratories are both equipped with in-house measurement calibrators who can conduct unified calibration management for all measuring tools, standard test blocks and instruments. By standardizing system of tool-collection, verification, calibration, the measuring tooling instruments can be effectively and legally managed.
Kunshan facility is capable to complete hydrostatic test up to 20,000 psi pressure and has independent assembly and test area of more than 200㎡; a pressure test room, high pressure test system, isolated test pump, three-station test machine, ball valve assembly press, lifting and fixed assembly workbench to meet assembly and test requirements of different product series.
All Roc-Master facilities have a complete quality assurance system and quality tracking, quality control process to ensure the product quality.
Our experienced and qualified technicians utilize NDT techniques to ensure high quality and reliability of our products during the production process. Final documentation package for clients will be issued after inspection, including all inspection process records, MPS, procedures, MTC, NDT reports etc.
- Positive Material Identification – PMI
We utilize the world's best 26-channel portable online PMI device to recheck chemical composition of the base material and cladding layer. The test reports will be completely saved in the computer on PMI
device and can be traced. Shanghai Research Institute of Materials and the imported calibration specimens ensure the PMI accuracy. - Ultrasonic Testing – UT
We utilize the world’s advanced Phased Array Ultrasonic Flaw Detector to do the ultrasonic testing on the integrity of the weld overlay layer and the base material to guarantee the cladding quality. Roc-Master strictly complies with the customer’s measuring standards of cladding thickness. - Penetration Testing – PT
All components are subjected to penetrate testing prior to overlay deposition as well as on completed items. Remote video-probe inspection technology is utilized on inspecting internal bore surface of pipe. We are able to examine inside surface of the pipes up to 6.5Mtr. - Magnetic Particle Testing – MT
We utilize fluorescence or visual techniques to test the surface defect on ferromagnetism components after all production phases are completed. - Visual Test – VT
Using remote video camera techniques and through the outlay screen, we can examine the cladding appearance and record the VT process media. VT process media will be submitted to the customers
as part of the quality assurance documentations. - Clad Layer Thickness Check
Innovative equipments will be used for the CRA clad layer thickness check, such as the Inconel 625 layer welded on the carbon steel and low alloy steel. The clad layer of the products will be checked
continuously to meet the customer’s requirements. - Radiographic inspection – RT
RT is outsourced and carried out by 3rd party professional RT testing companies on request. - Hydrostatic Test
Hydrostatic test for clad pipes is done by the pipe mill who uses special inspection equipments carrying out fast and accurate testing with pressure up to 92 Mpa.
Hydrostatic test for clad bends is done in house after butt-welding by Roc-Master’s qualified welders with pressure up to 20,000PSI.
