Segment Bolts, Tunnel Bolts, Shield Bolts Manufacturer
Anyang Railway Equipment Co., Ltd is the professional manufacturer of various segment bolts in mass production, its productivity is 10,000 pcs/day, widely used in subway shield, pipeline segment connection, shallow buried longitudinal segment bolt, building segment connection, subway segment connection.
The segment bolt is with straight or a certain radian shape, combines several pieces of segment together to connect and tighten. The segment bolts are divided into double-ended straight segment bolts and double-ended arc-shaped pipes. There are six types of segment bolts, hexagon head arc segment bolts, hexagon head arc thread segment bolts, hexagonal flange surface arc thread segment bolts, non-standard segment bolts, etc. , The grades are: 5.8, 6.8 and 8.8, the corresponding materials are Q235, 45#, 40Cr, etc., and the surface treatment is galvanized.
Application: subway shield, pipeline segment connection, shallow buried longitudinal segment bolt, building segment connection, subway segment connection.
The segment bolt is mainly used in the field of subway construction. The segments are connected together to form a cylindrical pipeline. Since the pipe bolts are used underground, they play a role in connecting and tightening. The environment is humid, which is easy to cause corrosion and rust of the segment bolts. Therefore, the surface treatment of the bolts is very important. Good anti-corrosion measures will prolong the service life of the bolts and pipes. If the anti-corrosion measures are not appropriate, rust will occur, and the inside of the bolt will be corroded, which will affect the mechanical properties of the bolt and its tensile strength.
Thicker hot-dip galvanized layer, Stronger corrosion resistance.
