Pipe MTC & Traceability
API 5L Steel Pipe MTC & Traceability
HYSP always insist the strict quality control and pursue the high standard welded steel pipe production and top level document job, no matter about the raw material coils and our mild carbon steel pipes. According to API 5L pipe specification, the traceability is also very important factor for one professional API 5L Pipe Mill.
Pipe MTC & Traceability (1) – Raw Material MTC & Incoming Material Test Report
When we purchase the raw material steel coils or plates, the material mill will issue us the raw material coil or plate mill’s test report. Even so, we still do the incoming material test and we will have the material incoming test report for each heat number, and all our documents and report have both Chinese Version and English Version.
Pipe MTC & Traceability (2) – Production Daily Records
Every working stand, there will be the table of each coil/heat chart. Every worker will do the daily records for documentation. Those records include UT records, hydro test records & graph, measurement records.
Pipe MTC & Traceability (3) – Pipe Lab Test Report & Pipe MTC
We will do the initial pipe production test to check the pipe quality and then start mass steel pipe production. Besides the UT test, hydro test, measurement, we also do mechanical test, chemical analysis etc. And all those test results, we will issue lab test report for each test, with those pipe test report, we will issue the mill’s test certificate-MTC.
We will issue any extra test report for any tests. We will have UT test report, residual magnetization, report, hydro test report, visual inspection report, dimensional inspection report.
Pipe MTC & Traceability (4) – Document Traceability
For API 5L line pipe production records and test report traceability, API 5L specification requires: the manufacturer shall establish and follow documented procedures for maintaining
a) the heat identity until all related chemical tests are performed and conformance with the specified requirements is shown,
b) the test-unit identity until all related mechanical tests are performed and conformance with the specified requirements is shown.
We establish our document procedure and have our file room to maintain all those material and pipe records and test report. All files are sort out as per heat number and can easily find out whenever it’s needed.
