Corrugated Wall Boiler Cover and Tank Production Process
Corrugated wall boilers are specially designed to balance transformer temperature and ensure uniform magnetic field distribution. Cover and tank production focuses on mechanical strength and sealing.
Material Selection
The material used is generally S235 or ST52 grade steel.
Objective: To ensure high strength, weldability, and forming capabilities.
Material certificates are verified during quality control.
Cutting and Preparation
Sheet metal is cut to project-appropriate dimensions using plasma, laser, or press brakes.
Cover and tank parts are numbered and tracked for production.
Wave Profile Forming
Sheet metal is formed into a corrugated wall shape.
Press machines or roll bending systems are used.
Corrugated depth and spacing are adjusted to meet standards.
Machining (Optional)
Drilling, milling, or plate drilling are performed if mounting holes or shaft penetrations are required.
Welding and Assembly
The cover and tank components are joined using welding.
After welding, the metal is checked with grinding and penetrant testing.
Sealing tolerances are ensured during assembly.
Heat Treatment (Optional)
Stress relief baking can be used to reduce stress on the metal and increase strength.
Surface Cleaning and Painting
The surface is cleaned of rust and burrs using sandblasting or similar methods.
Epoxy primer is applied.
A polyurethane or epoxy topcoat is applied.
Paint thickness is generally controlled between 80–120 microns.
Sealing and Assembly Check
Sealing is ensured with a gasket or O-ring during assembly of the tank and cover.
The cover closing mechanism and hinge tolerances are tested.
Quality Control
Dimension and tolerance control (wave height, width)
Weld testing (penetrant or ultrasonic)
Paint and surface inspection
Leak testing (pressure testing)
Packaging and Shipping
The product is packaged with scratch-resistant film or stretch wrap.
Appropriate palletizing is performed to prevent assembly damage during shipping.
