ETP, DHP, DLP & OFHC copper pipe and tube.
Material Overview
Copper pipe and tube — in ETP, DHP, DLP and OFHC coppers — is used across plumbing, refrigeration, HVAC and electrical applications for its excellent thermal and electrical conductivity, corrosion resistance and ease of jointing.
Grades & Standards
Available grades and the international standards commonly applied to copper pipes & tubes.
