Quality assurance system
Jiangsu PST Pressure Vessel Co., Ltd. was founded in 1978, has more than 30 years of production history of pressure vessels and non-standard equipment, has rich production experience and advanced production technology with sophisticated production equipment and testing equipment, has formulated relatively perfect rules and regulations and post responsibility system, quality assurance system has been in good running state.
1. Quality control
The company has formulated and issued the "pressure vessel Manufacturing and Quality Manual", which stipulates strict quality control procedures, and prepares process procedures, equipment and necessary tooling fixtures according to drawings.
To implement strict quality control of the materials for the production of products, the institute and the process room fill in the "material purchase application form" according to the requirements of the drawings, supply the company with the best order, and the purchased materials have a quality guarantee. After the materials are purchased, the person responsible for the materials goes to the site to check whether the steel mark is consistent with the warranty, and whether the appearance quality and size specifications of the materials meet the standards and drawing requirements. The physical and chemical laboratory of the company is responsible for the re-inspection of the mechanical properties and chemical composition of the material, the re-inspection mark, and the batch of materials are placed in the qualified material. Materials are used and issued by the material responsible person to check and mark and record the material transfer card, and submit the mark transfer card to the workshop to prevent mixed batch; The procurement, acceptance, storage, storage and use of outsourced parts and welding materials have strict management systems and operating procedures. After the product is fed, in the production process in strict accordance with the process regulations, the production process set up control points and stop points. After the completion of each process, the operator will self-check and sign on the process flow card after passing the important process self-check and submit to the inspector for re-check. After passing the process flow card, the operator will sign and confirm the process flow card. The unconfirmed process shall not be transferred to the next process. In addition, our company attaches great importance to the quality of welding, first according to the standard requirements of the welding process assessment, qualified and mature welding process to guide production, welding site in line with the requirements, welding personnel do a good job before, during and after welding inspection records, and weld seam X-ray inspection, product assembly after qualified assembly, hydraulic test according to the requirements of drawings. Airtight test, heat treatment, stirrer according to the drawing requirements to do static balance, dynamic balance test products after passing the grinding, sandblasting, planing and then paint, packaging factory. Taizhou, Jiangsu Province, quality and technical supervision Bureau of supervision and inspection personnel on the scene.
2. Production and quality control capabilities
