Ocean Supply And Engineering AThis is to certify that we have purchased Petrolatum tape and paste through “ Tianjin CNPetro Hitech Co.,LTD (Viscous）” for our Petronas pipeline project in Dec.2021 . We found that the performance of forever Petrolatum tape and paste is very good, and there is no failure of any of these Coating Materials and thus these are effective in our system -
Isolering og Blikk asWe purchased Butyl rubber tape from“Tianjin CNPetro Hitech Co.,LTD.from 2020 till now,the products are always arrival on time and without any quality problems. -
AIC GroupThis is to certify that we have purchased sealing tape and petrol tape from Tianjin CNPetro Hitech Co.,LTD LTD for our Anglo Persian project in June.2022 and always they are very much impressed about timely delivery and quality of the goods for which we are really pleased.

Product Description
HDD Heat-Shrinkable Sleeve That Meet All Relevant Global Standards
A three-layer system consisting of 100% solids two-component liquid epoxy primer and a heat shrink sleeve made from a high shear strength co-polymer adhesive and irradiation cross-linked, high-density polyethylene backing. This coating system replicates the structure and the performance of factory-applied three-layer PE coatings.
Fibre reinforced heat-shrinkable sleeve for field joint protection during directional drilling
A high-performance fibreglass reinforced sleeve specifically designed for girth weld corrosion protection for PE, PP and FBE coated pipes used for horizontal or directional drilling (HDD-Pull Through) applications. The reinforcement gives the backing greater abrasion and gouge resistance.
During installation, the epoxy is applied to the prepared pipe surfaceand the heat-shrinkable sleeve is immediately wrapped around thejoint over the wet epoxy. Heat is then applied to the sleeve, whichshrinks to form a tight fit around the joint. While curing, the epoxyforms strong mechanical and chemical bonds to the pipe surface & tothe copolymer adhesive layer. The radiation cross-linked outer layerforms a tough barrier against mechanical damage and moisturetransmission.
