Challenges in Metal Cleaning for Tube and Pipe Benders

Pipe benders experience more issues when it comes to cleaning their product than most other metal formers. Tubes present challenging for cleaning, due to the viscosity of the grease used to protect the metal throughout the bends as well as the different versions in shapes, tube diameters and orifice orientation. By simply using antiquated aqueous plunge tanks or fixtured bottle of spray impingement systems production will be slowed to a crawl by the disadvantage to clean tubes in a regular aqueous wash process. Solvent cleaning systems are able to solve these problems in an easy and cost effective manner.

A closed-circuit, hermetically sealed, professional washing system that uses solvent, is the ideal technology for applications where the aim is to achieve the highest possible, repeatable cleaning and drying out results as well as inexpensive procedure. The thickest, hardest impurities can be successfully removed during treatment in these systems. By utilizing a chapter of heated sprays, immersions, the application of ultrasonics during submersion and steam rinsing sealed solvent systems clean tough parts effectively and efficiently. In addition, through the application of heated blowing cycles and vacuum drying, the parts leave the process step absolutely bone dry to the touch regardless of orientation within the system.

Washing with solvents such as Perchlorethylene is suitable for tube applications because perc in short is able to break the surface tension between soil and metal up to six times more effectively than heated normal water and alkaline soap. This kind of allows the ultrasonic action put on the solvent while in submersion to break that surface tension of contaminant on the part even more effectively and permit it to be rinsed away. Each cycle in the cleaning process happens inside the same covered chamber, where one or more baskets of pipes, loaded in just about any orientation that is convenient, have been packed.

If the cycle starts, the door is shut and a spray impingement washing process is performed using hot solvent. The solvent is applied through moderate pressure spray aircraft directly onto the parts. This stage removes up to 90% of the soil from the parts. The soil laden solvent is drained from the process area while the continued spraying occurs and is delivered to a distilling device within the system, which boils the solvent into a water vapor. The soil remains in the still for following removal as the vapor is directed to a refrigerator which condenses the clean solvent into liquid for subsequent use. This handiwork process continues to happen throughout the complete procedure of the equipment.

The second cycle involves complete submersion of tubes within the process chamber, when ultrasonic mechanical action favors the detachment of the poison from both the outside and interior diameter of the tubes.

In the final stage of the cleaning cycle, direct vaporization is performed on the parts using solvent gases inside the chamber. These types of vapors come from the still, but instead than being sent to the chiller for immediate trust, they are directed to the process chamber for a final rinsing where they condense on the parts and cause associated with any remaining toxins. Then your parts move to the drying stage, which allows for almost total recovery of the solvent from the parts. A lot filters are necessary in a few machines to ensure conformity with environmental regulations.
