During the processing, we strictly follow customer requirements and select high-quality, standard steel pipes for cutting and processing. Then we perform thread processing. We select experienced engineers to use automatic lathes to process the threads of the pipe fittings; then we perform thread testing on the processed outer wires of the steel pipes to ensure that they are 100% qualified before leaving the factory. Then the threads are chamfered to protect the threads and facilitate installation; then the pipe fittings are treated with anti-rust oil and finally packaged for customer inspection.

The customer made an appointment with an experienced third-party testing company. We arranged vehicles to pick up and deliver the inspection personnel in advance, and prepared the products and tools for inspection in advance. After the inspectors arrived, they inspected and tested the product’s appearance, thread, length, weight, zinc layer thickness, pipe fitting strength, and customized logo in strict accordance with the inspection standards. They also inspected the product’s carton packaging, pallet packaging, and carton packaging. Tags are inspected and photographed. Finally, all pipe fittings passed the inspection.

We strictly control quality and strive to deliver the best products to customers, so that customers are satisfied with the quality and delivery time during the sales process, so that customers can win more markets and profits in the market.
