Oil and Gas Pipeline Girth Weld Protection Heat Shrinkable Sleeve Delivering Durable Insulation and Corrosion Resistance

Developed by Qingdao Huashida Machinery Co., Ltd. with over 20 years of industrial manufacturing experience, this high-efficiency, energy-saving heat shrinkable tape and sleeve production line is an intelligent integrated system dedicated to producing premium pipeline anti-corrosion and joint sealing materials.

Adopting cutting-edge extrusion, irradiation crosslinking, and online lamination technology, the line can manufacture standard two-layer heat shrinkable products and upgraded three-layer fiberglass reinforced heat shrinkable tape/sleeve, widely applied for joint corrosion protection, repair, and sealing of various municipal, oil and gas, and industrial pipelines.

The whole line features low energy consumption, low noise, stepless speed regulation, and a high degree of automation, leading the domestic and international industry in technical performance and product quality.

• Standard Products: 650mm width, Two-layer PE heat shrinkable tape, sleeve-type heat shrinkable sleeves, clip-on heat shrinkable sleeves
• Upgraded Products: Three-layer fiberglass reinforced PE heat shrinkable tape/sleeve

Hollow wall spiral wound pipes, steel-reinforced spiral corrugated pipes, plastic-steel spiral wound pipes, double-flat-wall plastic-steel spiral wound pipes, PVC-U sewage pipes, polyurethane foam insulated pipes (black and yellow jacket pipes), 3PE/2PE steel pipes, seamless steel pipes, large diameter wastewater pipes, and other ordinary steel pipelines.
