How to Ensure Our Product Quality?

Quality is the most important promise we made to our customers. We seek survival, development and performance by quality.

The quality of filtration equipment has a keen link to the quality of customers' final products, the safety of downstream key devices and the recovery rate of important materials. We guarantee that all our products are qualified from the aspects of raw material selection, production process control, finished products inspection and scientific after-sales processing. In addition, we have passed the ISO 9001 quality management system certification. We strictly implement the standard operating procedures, and conduct full inspection on each batch of products to ensure they are qualified before delivery to customers.

Strict Finished Product Inspection

After production, we will carry out strict quality inspection on all finished products to ensure all products are qualified before delivery to our customers.

Hydraulic test. Test the hydrostatic bearing capacity of filter housing and pipelines and check if there is leakage in weld seams.
Bubble point test. Test the integrity of the finished filter elements.
Welding process test. Test the welding process of the filer housing, including steel plate welding process test and perforated metal welding process test.
