Stainless Steel Condenser Tube
The heat exchange area per unit volume of the heat exchanger is big, the machine is compact, the alloy intake per unit heat exchange area is significantly less when a small diameter tubing is used, and the heat transfer coefficient is greater.

Product Description
The size of the heat exchanger tube has a fantastic impact on heat transfer since the heat exchanger tubing creates the heat transfer surface of the heat exchanger. The heat exchange area per unit volume of the heat exchanger is big, the machine is compact, the alloy intake per unit heat exchange area is significantly less when a small diameter tubing is used, and the heat transfer coefficient is greater.
Even though it's troublesome to manufacture, using austenitic stainless steel seamless tube for a heat exchange tube can prevent the issues. Since stainless steel seamless tubing has good corrosion resistance and surface, the manufacturing procedure is older, so stainless steel has no Slotted tubes would be the first choice for heat exchange tubes.

Production Process and Feature
Stainless steel seamless pipe manufacturing features: light manufacturing gear speedy construction speedwelding methodassortment of product specificationsdimensional precision wall thickness deviationsurface and higher yield. In the event of production, seamless pipes' price is more than 20% lower compared to steel pipes. Lately, my country has embraced the"welding-cold rolling" process to create stainless steel pipes. The cold-rolled coil is cut longitudinally according to the specifications, welded to a tube with a multi-gun argon arc welding machine, then cold-rolled (attracted ). The weld's performance indicators are the same as those of the base alloy, and the product quality is enhanced. The benefits of replacing stainless steel seamless tubes with stainless steel seamless tubes are getting more and more evident.
Application
The development trend of stainless steel seamless pipe is great. There have been improvements, especially in demand's regions are expanding. Additionally, as the practice of stainless steel seamless pipe will become more and more mature, it may slowly replace stainless steel welded pipe in several applications, such as: heat exchanger equipment pipe, medium and low pressure boiler tube, etc..
