Quality Control

• • Part 01

    Incoming Inspection Of Raw Materials. In addition to the inspection and test reports of the raw material from suppliers, our laboratory personnel will inspect the raw materials every time before the material enter our factory, take samples from each batch, check and carry out the inspection of the main performance and processing characteristics (for example moisture content, melt flow rate, purity), then compare with the quality assurance clause of the supplying contract and the inspection report of the raw material from suppliers. Only when the test results are within the allowable tolerance range, this batch of raw materials can be accepted.

  • Part 02

    Quality Control Standards. The quality of pipes and fittings not only depends on the quality of the PE compounds, but also on many control standards in the pipe production process. We produce pipes and fittings in accordance with the dimensions, wall thickness and tolerance required by international standards strictly. Continuous online control and manual inspection are used to inspect the production process at any time to ensure that ensure that each pipe exceeds the standard requirements before entering the next step.

  • Part 03

    Finished product testing. The incoming inspection of raw materials ensures that the delivered pipe compounds meet specific quality standards, and a large number of inspections must be carried out during and after production. These inspections include not only on-line inspections during production, but also sampling inspections in production for each batch products. It involves not only non-destructive experiments in the laboratory, but also destructive tests, such as dimensional inspection (diameter, wall thickness and out-of-roundness), appearance inspection, short-term experiment, long-term experiment (internal pressure and destruction experiment), and finished product MFR experiment, packaging inspection, etc. The finished product can be shipped only after strict testing is carried out in accordance with international standards.

  • Part 04

    Inspection certificate. In order to ensure continuous high quality standards, we compile the internal test records of each batch into a book, which is used for daily work records and inspection reports, so that all internal test results of each batch of products are clear, the products received by customers are qualified in accordance with related product standards. These documents must be kept for no less than 10 years to ensure that the work and inspection reports can be repeated and traced at any time.

  • Part 05

    Remarks and traceability. A lot of additional information on the pipes and fittings that we produced are provided, such as raw materials, production machines, production dates, sizes and standards, raw material grades, etc. These marks are printed on the pipes by laser coding, with an interval of no more than 1 m, Which can be recognized even after being buried underground for a long time and faded. At any time, the production history of the product can be traced through these marks.

  • Part 06

    Quality management. Strict quality management is not only by increasing the frequency of quality control to find problems, but the ISO9001 system pays more attention to avoiding errors at the very beginning. We strictly follow the 8S management system and implement the quality assurance clauses within the scope of the ISO9001: 2015 quality management system. Make the internal control process and system audit form a systematic record and continuous evaluation.

  • Bingo pipeline does hold the ISO9001:2015 certificate of registration that certifies the Quality Management System of Bingo pipeline. More practical project cases have also proved that our high performance HDPE pipe and fittings satisfy the oil, gas, mining, industrial, municipal water markets and other applications.

  • Part 07

    External audit. In addition to the strict internal quality control system certification, all products are also subject to regular external product audits in accordance with relevant procedures, obtaining relevant registration and approval, and forming a supervision agreement with a third-party independent testing agency.
