CONTROLE DE QUALIDADE
Gerenciamento de fornecedores
Tianjin United Steel Piping Co., Ltd (TUSPIPE) conducts strict audits of suppliers, verifying their production qualifications and capacity to ensure that the raw material quality control procedures meet requirements. In addition, the company evaluates suppliers annually and assesses past performance in quality control, document control, delivery times, and other factors to ensure suppliers meet our product quality requirements.
Antes da produção
After getting the hot-rolled coil, the quality assurance team sends an inspector. They check for cracks, pits, and other surface defects. These issues could impact later production. Inspection staff not only conduct visual checks but also take samples from the coil plate. They do this for chemical composition analysis and mechanical testing, following standard requirements. Then they compare the results with the material quality certificate issued by the coil plate supplier. If the analysis results do not meet the standard requirements, the raw material will be returned to the supplier for replacement.
Durante a produção
To ensure our carbon steel pipes meet the required standards, quality engineers, on-site inspection personnel, and front-line production workers need to make great efforts. In the production process, we will carry out the following inspections and tests on the steel pipe according to the standard requirements:
Teste de tração
That measures the force required to pull on a pipe. By analyzing these results, engineers can determine whether a material is suitable for its intended application.
Teste metalográfico
Metallographic tests are an important means of experimental research on metal materials.
Teste de impacto Charpy
It is generally a test method used to determine the safety, reliability, and effectiveness of a product when subjected to external impacts or actions.
Análise de componentes químicos
Para a análise espectral, pode ser usado o espectro de emissão ou o espectro de absorção. Esse método tem a vantagem de ser muito sensível e rápido.
Teste de rasgo com peso de queda
This experiment uses a drop hammer at a specified height to break the sample in the supported beam state and evaluate the relevant performance results.
Teste de achatamento
The flattening test is a method used to assess the deformation performance of a metal tube flattened to a specified size and to detect defects.
Revestimento, marcação e embalagem
After the welded steel pipe is produced, Tianjin United Steel Piping Co., Ltd (TUSPIPE) applies a surface coating to the carbon steel pipe, according to the customer’s requirements, to prevent corrosion. Standard coated with black paint, varnish, and anti-rust oil, these materials can provide temporary anti-rust protection during transportation. If FBE, PE, or PP coatings are needed, the pipes will be transported and finished in a coating mill.
We apply a bar code to the inner wall of each steel pipe, and each bar code is unique to each pipe end. The bar code is equivalent to the ID card for each unit of steel pipe, recording the heat number, tube number, steel grade, and production information for each pipe. After completing the coating process, production workers scan the bar code to retrieve the corresponding product information and mark the pipes in accordance with standard and contract requirements to ensure product traceability. Generally speaking, product packaging plays a crucial role in protecting products during transportation, so the company is also very concerned about this process. Based on the size, coating, and other processing information of the steel pipe, the company usually uses end caps, PVC wrap, nylon slings, galvanized strips, fumigated wood, and other materials to protect the steel pipe. At the same time, the engineers can generate a customized packing scheme for customers who need more robust, stable, and easy-to-unload packaging solutions.
Antes da remessa
Before delivery to customers, the inspector rechecks the appearance, packaging, markings, labels, tags, and other specifications of the black steel pipe to ensure customers do not receive any defective products. After passing inspection, the quality assurance department of Tianjin United Steel Piping Co., Ltd (TUSPIPE) issues a mill test certificate for each batch of shipped products.
