Polyolefin Coated U-Bolts & Fasteners
Stud Bolts, Nuts, Screws, Threaded Rod & Washers
Polyolefin Coated U-Bolts can easily avoid corrosion between the pipe and U-bolt with high shell life.
Polyolefin protection jacket is shrunk over the U-bolt which provides a barrier to avoid metal to metal contact with high compressive strength and is extreme resistant against abrasion. Polyolefin can be used in harsh environments while it is UV resistant and works from -55°C up to +125°C. Polyolefin Coated U Bolts are most frequently used in piping found in refineries, compressor stations, pumping stations, and chemical plants as it provides high protection against corrosion and mechanical damage. They are particularly useful as non-load bearing guides on bridge mains.
Armorcote Polyolefin Coated U Bolts & Fasteners
Armorcote Brand Polyolefin
The ArmorCote™ u-bolt coating has evolved from decades of proven technology. The cross-linked polyolefin material provides a coating with extremely high compressive strength and tremendous abrasion resistance. ArmorCote™ has a low coefficient of friction that allows for pipe movement without damage to the pipe coating. ArmorCote™ is a unique thermoplastic that is UV stabilized to maintain the integrity of the product even under prolonged exposure to direct sunlight. Unlike minimum millage dipped coatings or hand wrapped rubber applications, ArmorCote™ resists tearing and will not unravel over time.Polyolefin Coated U-Bolts Properties
