According to the current trend of world development, bright basic continuous heat treatment stainless steel pipe is divided into 3 types. Bright heat treatment stainless steel pipe, roller hearth furnace for such a large size, large quantities of steel heat treatment, production of 1.0t or more hours, you can use the protection of high-purity hydrogen gas, decomposition of ammonia and other protective gas. Can be equipped with convection cooling system for faster cooling pipe.
Bright heat treatment furnace mesh belt furnace for such a small-diameter thin-walled precision steel tubes, hour output of about 0.3 ~ 1.0t, pipe lengths up to 40m, can be processed into the capillary volume; with convection cooling system can also for rapid cooling. You can use gas or electric heating are applicable to a variety of protective gas. Stainless steel pipe after heat treatment no scratches, good brightness.
Muffle furnace tube placed in continuous light bracket, in the muffle tube is heated, at a lower cost of processing high-quality small diameter thick wall stainless steel pipe, or more hours of production in the 0.3t. For economic use of protective gas, heating the heat source for gas, oil or electricity. Should be based on martensitic, ferritic, austenitic and duplex stainless steels of different species, choose a different heat treatment furnace and process systems. 4 is equipped with modern finishing equipment to enhance quality control quality control of stainless steel finishing process is an important part of their equipment set, the quality of nondestructive testing methods is essential.
Non-destructive testing technology with more manufacturers to use eddy current, ultrasonic flaw detection units combined in the laser diameter measuring unit, ultrasonic thickness measurement device. Production plant in the stainless steel pipe factory, from more than one link always has quality. This combination of detection units with advanced treatment systems, the measured signals of all the data and by computer processing, storage, automation and production efficiency. Precision straightening machine, cold and spin necking push the machine, long 6 to 8 polishing machine, full marking devices, are widely used the world’s high-efficiency stainless steel pipe finishing equipment.
