The pipe seam the anchor pipe seam 43 the Bolt Specification tube seam bolt manufacturers seam bolt pipe seam bolt the Model MF diameter (mm) / Length (mm), wherein M represents an "anchor". F indicates the seam tube. MF43/1600 said slit pipe bolt, the outer diameter of 43mm, length as 1600mm. The pipe seam bolt also called rock friction stabilizer seam pipe anchor is a very dedicated support supplies, is the the underground culverts roof and other advanced materials engineering support, manufacturing process is simple, easy to use, underground anchor shotcrete support with a strong anchor, tensile strength, strong expansion force, so that the whole roof to become one. , Working principle and characteristics pipe joints anchor is a total length of anchor, take the initiative to strengthening the surrounding rock of the new anchor, pipe joints anchor three-dimensional part of a longitudinal slit high-strength steel than the tube, when installed in smaller diameter drilling hole wall along the entire length of the radial pressure is applied and to prevent the the surrounding rock decline of friction, the plus bolt carrier pallet load bearing capacity, so that the surrounding rock in a three-way force, and to achieve great rock formations. Second, the initial anchoring force of the pipe joints anchor performance and specifications, the main technical performance (1): 3 to 7 tons; (2) pipe ring pull-off load: 8 to 10 tons; (3) anchor tube tensile Breaking capacity: 12 to 13 tons; (4) corrosion resistance than A3 steel, 20 to 30% for long-term use Our company specializes in mining support equipment, service and the majority of coal and the construction industry business, to provide you with the most quality service is our consistent aim. Welcome to inquire, Centennial Coal, integrity first!
