Tubular heat exchanger
A shell-and-tube heat exchanger mainly consists of four parts: the shell, tube bundle, tube sheet, and end caps. Shell: An outer cylindrical body that provides protection and housing for the tube bundle, through which one type of fluid (such as a hot or cold fluid) flows. Tube bundle: The core component, consisting of multiple heat transfer tubes arranged in a specific pattern (such as equilateral triangles or squares) and fixed to the tube sheet, forming the heat transfer surface. Another fluid flows inside the tubes, exchanging heat with the fluid inside the shell. Tube sheet: Located at both ends of the shell, used to fix the heat transfer tubes and separate the tube-side and shell-side fluids, ensuring that the two fluids do not mix. End caps: Installed at both ends of the shell, equipped with fluid inlets and outlets, connected to external pipes via connecting pipes to realize the entry, exit, and distribution of fluid.
Product Details
Advantages:
Strict welding standard: Firm, aesthetic weld seams; sheet metal & square tubes welded at perfect vertical angles, zero misalignment.
Full post-weld finishing: Complete weld slag removal, thorough grinding for smooth, flawless surfaces; all burrs, flash edges on holes and panels fully eliminated.
Sharp edge deburring & blunting: All sharp corners and sharp edges rounded off to avoid scratches and safety hazards.
Deformation control system: Stress relief annealing + flat straightening processes to minimize post-processing distortion, ensure flatness meets strict tolerance standards.
Dual fastening solution: Bolts & nuts fully tightened then spot-welded for ultra-reliable, long-lasting connection.
Complete pre-assembly inspection: Every finished cabinet undergoes trial fitting with brackets and covers, all bolts fit smoothly without assembly interference.
Uniform matte sand-texture powder coating with precise thread protection during spraying.
Consistent color coverage, free of pinholes, shrinkage cavities and paint sagging; coating thickness complies with official technical specifications.
Shot blasting pre-treatment before powder coating to boost coating adhesion, anti-rust and anti-corrosion performance.
Quality control system：
Every production step is inspected from raw material forming, welding, surface finishing to pre-assembly testing, with all dimensional, appearance, electrical and corrosion indicators strictly aligned with international technical standards, delivering stable, durable and high-standard custom metal & busbar solutions.
Product Parameters
Performance Advantages | Typical manifestations |
High-efficiency Heat Transfer | By increasing the heat transfer area (multi-tube combination) and optimizing the fluid flow state (such as baffle design), the heat transfer coefficient can be improved, enabling rapid heat exchange. |
Highly Adaptable | The pipe diameter, length, number of pipes, and arrangement can be adjusted according to operating conditions to meet heat exchange requirements of different flow rates, temperatures, and pressures. |
Reliable Structure | Its robust housing and tubing design allows it to withstand high pressures and temperatures, making it suitable for a variety of complex industrial environments. |
Easy To Maintain | Some types (such as floating head type) are easy to disassemble and clean, reducing equipment maintenance costs and downtime. |
