Large diameter thin-walled tubes

USES: mainly used in household and commercial central air conditioning refrigeration engineering system.With large tonnage water seal extrusion machine production, the product material density, compression performance is good, both inside and outside surface without residual oil, dust content is low, very suitable for new refrigerant refrigeration system.Products of the technical indicators reach JISH3300:1997, GB/T 26024-2010, EN 12735-1:01, ASTM B280 technical requirements.
