SupAnchor H25S Self Drilling Fiberglass Reinforcing Bars Features   Due to it's cuttability SupFRP TM  Self-Drilling Rock Bolt is an economical alternative and also offers enormous advantages for modern rapid heating methods in tunneling.Furthermore the cuttability protects the machinery and avoids obstructions while drifting or enlarging tunnels. The rock bolt has a high radial pressure resistance for injections with resins or grout and is corrosion resistant for permanent support.The SupFRP TM offers a high tensile strength and can carry high loads. Its low weight with high torsional strength makes the bolt well suited for works in loose rock up to a maximum hardness of 60–70 Mpa. Mining Application 1.Support in rock 2.Temporary application with cutting ability 3.Permanent application with high durability 4.Slope stabilization 5.Strata support 6.Back-anchoring
In the PP ventilation piping system, the PP Elbow is the pipe that
changes the direction of the pipe:Bend
molding.Injection elbow.Socket
elbow, etc. There are 45 DEG and 90 DEG to 180 DEG three most commonly used,In addition, according to the project needs, including 60 degrees
and other non normal angle elbow.Elbow and pipe
connections are: direct welding (the most commonly used way), flange
connection, hot melt connection, electric melting connection, threaded
connection and socket connection.
