Scaling & Cleaning Heat Exchangers
Due to the development of modern industry, the heat exchanger equipment will inevitably form many types of fouling such as coking, oil residue, scaling, sediment, polymer deposits, corrosion, mold et al. after long-term working. These deposits have a negative influence on the equipment performance as well as the safety, particularly the heat exchanger plates that are among the key components. Incorrect or unscientific cleaning methods can lead not only to great economic losses but also to disastrous accidents.
To address this important challenge, the cleaning of heat exchanger equipment must be seen as a critical part of maintenance work. Embracing novel and eco-friendly cleaning methods can bypass risks while preserving operational performance.
Procedures for Scrubbing Stainless Steel Panels and Seals
- Preliminary Examination
Acquire archive data on the stainless steel panels and seals applied in high-temperature, corrosive settings. Judge corrosion degrees on the plates and the aging of seals. Dependent on this evaluation, craft a customized scrubbing scheme.
- Careful Gasket Removal
The gaskets holding the plates together must be detached precisely to avoid inflicting harm in the dismantling work.
- Plate Cleaning Process
Specialized machines are employed to scour the plates under strict rules. Cleaning solutions are tailored based on each situation’s specifics. The cleaning involves.
∗ Pre-Cleaning Stage
Loose dirt and fouling are wiped away using high-pressure water sprays and manual scrubbing. For extreme fouling, high-pressure steam cleaning may be applied.
∗ Power-Blasting Method
For rigid scales resistant to chemicals, power-blasting combined with high-pressure water or steam is utilized.
∗ Chemical Soaking
Plates are submerged in a customized blend of chemicals designed for the heat exchanger’s usage. A mix of changing chemicals, controlled temperatures, and agitation confirms optimal cleansing.
∗ Liquid Nitrogen Treatment
For gaskets bonded with epoxy glue or stubborn scales, plates are immersed in liquid nitrogen to weaken adhesive bonds and remove lingering residues thoroughly.
- Dye Penetrant Examination
The inspected plates underwent a dye penetrant test to scour for any flaws, fractures, or imperfections, making sure they satisfied the criteria for fresh plates.
- Recleaning and Letting Dry
The plates were scrubbed again after examination and blasted with compressed air to completely dewater and bring back their glossy, unblemished appearance.
- Final Surface Appraisal
A painstaking appraisal of the refurbished plates was performed, noting any minute defects and cataloging them for ensuing phases.
- Gasket Assembly
With care, the refurbished gaskets were precisely reinstalled onto the thoroughly scoured plates, restoring the critical seal.
- Packing and Shipping
The plates were expertly packaged for transit employing sturdy, protective materials to safeguard against scratches or fractures en route, delivering the parts in pristine condition as required.
