Pipeline Casing Insulator

Pipeline Casing Insulator
 

● Application scope
Pipeline casing insulator (patent number:ZL 2008 2 0125587.9,passed GB/T19001-2008/ISO9001:2008 certificate of quality management system cetification,API Specification Q1, Xi’an United Nation Quality Detection test report)is uesd for the oil, gas, chemical, water industry. It is used to support and insulate the carrier pipe from casing pipe through which it must pass and are used in river crossing, highway and railroad crossing. It can protect the internal coating.

● Features
Excellent design , domestic boutique
ZD series of pipeline casing insulator are designed in accordance with domestic geographical and climatic conditions and absorb technology adavangages of foreign products. The products have been widely recognized by industry experts.

Applicability
Applicable to a variety of pipeline diameters, from DN30-DN1400, feet height from 36mm-110mm. For DN800 and larger diameter, the casing insulators are equipped with reinforcing tape to enhance impact resistance, fastening performance and applicable ability of cathodic protection facilities installation .

Good firmness
ZD series of pipeline casing insulators have a dual reinforcement measures with four fastening wire, connected by stainless steel bolts, scientifically and conveniently fastened on the pipeline, completely avoid casing insulator or individual fastening bracket damaged due to large diameter and long crossing distance during construction period, to ensure pipeline external coating can be effectively protected.

Construction speed fast, reduce construction costs
ZD Series of casing insulators is plug-in type, with lined 4mm-6mm insulation paste, easy to install.
