Welcome To Our Factory
Advanced Shell and Tube Heat Exchanger Manufacturer
The high-efficiency heat exchange tubes used in our heat exchangers are professionally manufactured and supplied in-house. Their performance can reach a leading professional level in the domestic industry. Our annual output of copper and copper alloy, stainless steel, and titanium alloy heat exchange tubes exceeds 2,000 tons, fully meeting our requirements for supporting production and quality control.
Relying on our own high-efficiency heat exchange tube production base, we strengthen quality control from the core heat transfer components, ensuring stable performance, reliable delivery, and batch production capability for shell and tube heat exchangers. At present, the product repair rate is controlled below 0.12%, and the standard delivery time for regular products can reach 6–8 days.
Production Process
A relatively complete factory production process has been established around shell-and-tube heat exchange components such as condensers and evaporators. From the issuance of production drawings to material preparation, component processing, assembly and welding, testing and acceptance, and delivery, each link is seamlessly connected to ensure accurate product structure, stable manufacturing, and reliable delivery.
1.Engineering Drawing Design & Production Release
Before production, our engineering team confirms the technical parameters, working conditions, and project requirements, then releases the approved drawings to the workshop.
2.Material Preparation, Stock Check & Procurement
Based on the confirmed bill of materials, shell plates, heat exchange tubes, tube sheets, flanges, and related components are prepared from stock or arranged for procurement.
3.Shell Plate & Tube Sheet Blanking
Shell plates and tube sheets are cut according to drawing dimensions, providing accurate base components for rolling, machining, and welding.
4.Shell Rolling & Welding
The shell plate is rolled into a cylindrical structure and welded to form the main pressure-bearing shell of the heat exchanger.
5.Tube Sheet Drilling, Grooving & Face Machining
Tube sheets are drilled, grooved, and face-machined to ensure accurate tube positioning, stable expansion, and reliable sealing performance.
6.Shell and Tube Sheet Welding Assembly
The shell, tube sheets, and related structural parts are positioned, assembled, and welded to form the main body of the heat exchanger.
7.Tube Insertion & Tube Expansion
Heat exchange tubes are inserted through the tube sheet holes and expanded tightly to create secure tube-to-tube-sheet connections and reduce leakage risk.
8.End Cover Assembly
End covers, flanges, gaskets, and fasteners are installed to complete the fluid channel structure and prepare the unit for further inspection.
9.Air Tightness Testing
Air tightness testing is carried out to verify sealing performance and ensure safe, stable operation under actual working conditions.
10.Surface Treatment & Painting
The product surface is cleaned, treated, and painted to improve corrosion resistance, appearance quality, and long-term durability.
11.Final Inspection & Delivery
Before delivery, each finished product is inspected for appearance, dimensions, sealing performance, and documentation to ensure qualified products are shipped to customers.
