I. Product Overview

Photo-sensitive glass fiber pre-impregnated tape is developed after summarizing the advantages and disadvantages of similar products. The product is intended for use as protective material for directional crossing of pipelines.

The product is mainly used for the jointing of new pipeline ordinary sections, the jointing of horizontal crossing sections in new pipelines, and the overall wrapping of horizontal crossing sections in new pipelines.

II. Product Features

High strength, high rigidity, and excellent resistance to deformation. As a material for pipeline crossing protection, it is imperative to possess high strength and excellent resistance to deformation to prevent tearing by gravel within the borehole.

High tensile strength, excellent crack resistance.

High adhesion for 3-layer PE and fused epoxy powder coating. All photo-sensitive glass fiber reinforced plastic protective sleeves are non-adhesive in nature and require bonding to the substrate through an intermediate low-coating material.

High surface hardness. Just like steel materials, to achieve high scratch, wear, and piercing resistance, surface hardening treatment is necessary while enhancing the overall strength of the material. This is why gears, cutting tools, shafts, and shaft sleeves we commonly use are all surface hardened.

No hollow joint overall wrapping technology. Hollowing, especially continuous hollowing, is one of the main reasons for the damage to the pipeline when it穿越 the outer protective coating.

High shrinkage rate. The photo-sensitive glass fiber reinforced plastic protective sleeve pre-impregnated tape has a high shrinkage rate of 1.5-3%.
