DHP Pipe

Farmer’s Copper Ltd. maintains an inventory of C12200 Copper pipe up to 8” nominal pipe size in schedule 40 and schedule 80 wall thicknesses per ASTM B42.

C122 DHP is commercially pure copper, which has been deoxidized with phosphorus, leaving relatively high residual phosphorus content. Copper alloy 122 is not susceptible to hydrogen embriddlement, but is relatively low electrical conductivity due to the amount of phosphorous content.

Farmer’s Copper Ltd. has been in the metal industry since 1920 and our knowledgeable sales staff is available to assist you in your copper pipe requirements. To complement our pipe, Farmer’s Copper Ltd. handles copper butt-weld fittings per ANSI B16.9, and bronze flanges.
