Client satisfaction and quality assurance

about

Client Satisfaction is Our Reputation. 100% Quality Assurance Systems

every individual hanwei pipe, fitting and flange that is provided to our clients must exceed our stringent and proprietary, quality control, hydro-testing system at a minimum of 1.5x our product’s operating pressure rating. we also carry out catastrophic burst tests with our performance requirement set at a minimum of 3x the pressure rating of our products.

Hanwei Product and Performance Standards.
