Made in accordane with the applicable rules and laws no. 46 of 5th March 1990 and Presidential Decree no. 1095 dated 3rd August 1968, it is an ESENCOR CU DHP copper alloy pipe complying with European Standard EN 1057 - annealed in coils and phosphorous-deoxidised, with minimum 99.9% copper content and and 0.015-0.040 % phosphorous, in compliance with UN1 5649/71 series B, heavy, bearing the marking "ESENCOR OD x thickness EN W57 CU DHP 99.9% SLM 1 00".

Isotop insulated copper pipe is coated with a yellow or red foam polyethylene no-crush rigid sheath comprised of low-density closed cells, extruded directly onto the copper pipe to ensure good mechanical protection. Non- toxic, odourless and free from chlorofluorocarbons (CFC). Particularly suitable for use on building sites.


The Isoclima insulating sheath, wich adheres to a non-flammable base, melts flamelessly and thus belongs to self-extinguishing CLASS 1 (UNI 9177-87) and bears the progressive marking "00 ISO TOP RIV. L. 10/91 OD x thickness CL.1 with ESENCOR copper pipe", as well as an indication of the date, time and production line for quality control purposes. The main features are excellent elasticity and flexibility, true thicknesses to ensure optimal insulation and excellent resistance to water vapour.


Isotop no-crush insulated copper pipe is mainly used on building sites where there is a greater risk of the pipe suffering impact, abrasion and contact with highly aggressive products. Particolary suitable for use in heating, hot water and plumbing systems in general.
