The main production process of coaxial heat exchanger: material selection----tube drawing----ultrasonic cleaning---- bend tube----interface welding----testing (helium inspection + water inspection)----semi-finished product cleaning----electrophoresis----packaging.
Shenshi pays special attention to product quality. From the source, we insist on high-quality design in the first step of raw material selection. We select raw materials with excellent thickness and pressure. The finished product has passed various rigorous reliability experimental tests to make it more pressure-resistant, corrosion-resistant, and has a life expectancy that far exceeds that of similar products on the market.
And the product passes the two processes of helium inspection and water inspection to ensure that the product does not leak and ensure product quality.
Shenshi focus on each process of the product, to provide customers with the highest quality products.
