The company adopts advanced, efficient and mature production management mode. The company selects Walsin Lihwa and Yongxing special steel base materials as the leading materials for the production of high-quality stainless steel, providing the most reliable and safest stainless steel pipes and fittings for global users. It mainly produces seamless pipes, bright and annealed pipes, heat exchange pipes, pipe fittings, flanges and other products.
Stainless steel butt welding tees are used in the rainy season, especially in the basement. Drainage trenches and water collection wells should be dug first, and water pumps, rubber hoses and other pumping equipment should be prepared to facilitate pumping. It should be strictly prevented from being soaked by rainwater to prevent floating pipes. Backfill.
Stainless steel butt welding tees should be treated specially in special periods, as follows:
1. When performing asbestos-cement interface, hot water mixing materials should be used, and the water temperature should not exceed 500°C, such as when expanding cement interface.
2. When the temperature is lower than -50°C, the above two data interfaces should not be performed.
3. After the interface is completed, the sticky mud mixed with salt water can be used for sealing and maintenance, and the grass curtain should be covered.
4. During the pressure test, the exposed pipes or joints should be covered with straw curtains, and the pipe body without joints should be backfilled. After the pressure test, the water should be drained as soon as possible, and all preparations before the pressure test and after the pressure test should be done. Drainage and other operations.
