MF43 series seam pipe seam anchor of anchor tube Long slit tube bolt 
 Pipe seam pipe seam anchor bolt slotted bolt rock friction stability 
 Main Specifications: MF45 MF43 MF40 MF39 MF33 
 Length: 1200MM-3600MM 
 A, the product has a full anchor end anchor combination of easy installation and immediately after installation carrying characteristics, mainly applicable to the mining and metallurgy, water, electricity, railways and other underground construction of the temporary or permanent support. A slit tube bolt working principle and characteristics of the slit tube bolt is a full-length anchoring, take the initiative to reinforce the new anchor of the surrounding rock, it is three-dimensional part of a longitudinal slotted high strength steel pipe, installed in more than diameter smaller drilling immediately in the full-length within the pore walls exert radial pressure and prevent the friction of the surrounding rock fell and bolt tray pallet load bearing capacity, so that the surrounding rock in a three-way by stress state and rock great. In the case of blasting vibration surrounding rock anchor shift have increased significantly in the post-anchoring force, when the surrounding rock occurrence of significant displacement, the anchor does not lose its support resistance, which have better characteristics than the rise of shell-and-bolt . 
 Second, the slit tube bolt main performance and specifications 
 1, the initial anchoring force of the main technical performance (1): 3 to 7 tons; (2) tube ring pull off load: 8 to 10 tons; (3) of the anchor tube tensile breaking capacity: 12 to 13 tons; (4 ) resistant to corrosion 20 ~ 30% higher than the A3 steel, which will help long-term use
