Are there US standards for UPVC pipes and PP plastic pipes? Are the flanges used American standard 150Lb flanges? ?
There are some. You can refer to the product specifications of one manufacturer at: http://www.hershey.com.cn/product.php?mode=show&cid=79&pid=50 (not for advertising purposes)
But it seems that flanges of 150Lb don’t meet the American standards, right? ?
It should be available; I remember buying it together with pipes, made of CPVC material. However, when I visited the supplier’s factory, I saw materials made of UPVC and PP as well. You can contact the supplier to ask for information.
