2 T-H SAW PIPE Foolproof efficiency and safety. A true fact. In Villacero we continue working to consolidate our company as leader in the markets that we attend, offering our customers products and services that meet the highest international standards. Conscious of this commitment we have now included in our pipe portfolio large diameter helical SAW pipe, utilized mainly for the conduction of water, gas, air liquids and hydrocarbons in large scale projects. Our new plant at Pesqueria Nuevo Leon, is focused on this product line, with diameters in the range of 20 to 120 inches, with lengths of 16 meters, and different finishes such as black and with inside or outside coating. With a highly specialized human resource, together with a state of the art technology support, our production in this plant strictly meets in every process the principal standards of national and international organizations such as: API (American Petroleum Institute), ISO (International Standard Organization), ASTM (American Society for Testing and Materials), AWWA (American Water Works Association).
