Note well drilling rig drill rig drill rig maintenance during use, you need to do every time the maintenance work, such as drill pipe every 100 hours you need to do maintenance work, also need to check the chain surface drill strength, cracks, then the need for timely replacement rig accessories, to prevent accidents, after all, safety is the most important. Drill production well drilling rig is also necessary to prevent the emergence of the phenomenon with a rod, drill pipe in use, the use of anti-corrosion measures are also needed, if it is in the sea, then long auger or offshore construction operations, the need for timely cleaning drill pipe to prevent rust corrosion . Accessories well drilling rig drill on the demolition or replacement do not arbitrarily reverse circulation drilling rig, to prevent accidents, this is the most important. The most commonly used connection method rig Shandong Dragon Industry Machinery Co., Ltd. is professional development, production of various types of mining equipment backbone enterprises, the production of various types of submersible drilling rig, water well drilling rigs and other products. Today, let us work together to understand the connection requirements for crawler drilling rig: The rig currently used connection method (1) snap connector technology, mainly used for metal pipe. Threaded connection can be divided into male and female connections and then planting snap connector. (2) welded connection, it is divided into welded connection, mainly used for large-diameter pipe for quality: plastic welding, mainly used for plastic pipe. (3) screw connection, and more for large diameter shallow wells. (4) adhesive, mainly used in plastic pipe and glass pipe. (5) socket connection, mainly for shallow wells, down into the bell handcuffs iron pipes and hard PVC pipe.
