Pipe seam anchor/friction anchor
SKU: 6920307019f2eedfb850d0c6
Pipe seam anchor, also known as split type anchor or friction bolt, is an indispensable advanced material in underground mining support. Split bolt is a very special type of support product, which is an advanced material used for roof support in underground coal mines, copper mines, or gold mines. Friction rockbolts have been used in the international mining industry for decades and are considered the simplest ground support in the metal mining industry.
Details
Production Process: The split set anchor adopts advanced manufacturing techniques to ensure excellent mechanical properties and durability. The production process includes:
Steel Pipe Manufacturing: High-quality low-alloy steel or carbon steel materials are used to produce the anchor pipe body with precision instruments, ensuring high tensile strength and ductility. Welding Technology: High-precision pipe seam welding technology ensures strong seams without welding defects, guaranteeing product integrity and strength. Surface Treatment: The split set anchor surface is typically treated with hot-dip galvanizing or spray coating, providing excellent corrosion resistance and extending service life. Mechanical Performance Testing: Each batch undergoes rigorous mechanical tests, including tensile, bending, and shear tests, to ensure compliance with design standards.
