What we do before cast iron pipes delivery?
Our company pays more attention on product quality, so we have our own QC team.
All of our products will be inspected before delivery.
Take the cast iron pipes for example, we have more than 8 years of selling cast iron pipes. We know very well how we should control the quality.
The inspection procedure: surface, dimension measurement, unit weight, wall thickness, and the very important step is hydrostatic test, the the package.
We make sure all of the cast iron pipes sent from our company is high quality.
