Add to Cart
One of the engineering marvels of modern times is the Mastic Heat Shrinkable Sleeve 2-Layer System. This system is designed for the ready-to-fit assembly of corrosion protection for field girth weld joints in water supply or gas distribution and transmission networks. Additionally, it is specially designed for use in moderate climates with low and middle shear or low stress environments.
The first layer of this system is a low preheat middle shear strength half-rigid mastic sealant. This provides a strong, reliable seal for the girth weld joint. The second layer is an extruded radiation cross linked heat shrinkable high density polyethylene backing with TIP (Temperature Indicator Pattern). This layer provides additional strength and protection against corrosion and environmental factors.
One of the most impressive features of this system is its compatibility with standard pipe coatings. This means that it can be used on both coated and uncoated pipe sections and is ideal for large diameter water pipes.
To ensure maximum efficiency and durability, the Mastic Heat Shrinkable Sleeve 2-Layer System is designed for minimum preheating. The user can easily apply this system to any water or gas pipe joint without the need for extensive heating or preparation.
Overall, the Mastic Heat Shrinkable Sleeve 2-Layer System is a reliable and effective solution for protecting water and gas pipe joints against corrosion and environmental factors. Its innovative design and ease of application make it a go-to choice for many professionals in the field.
