The MOTOSHTORM bit is designed for easy ice drilling with a motor engine in any weather conditions. Due to the exact attack angle of blades, drilling is extremely fast. Reliable polymer coating withstands temperature fluctuations and heavy mechanical loads. Polymer powder coating is applied using European hightech equipment. The bit can be attached to a screwdriver or a motor engine. To connect the bit to the motordrill shaft, you must use a screw, a washer, and a nut, which are installed using the keys included in the kit. When attaching the bit to a screwdriver, an adapter (sold separately) and a wing screw (included) are required. If the ice is more than one meter thick, then an extension (sold separately) must be installed on the bit, which will increase the drilling depth by 2540 cm.

During the construction of an industrial facility, much attention is paid to the strength of the service pipelines fasteners. It is also necessary to provide reliable connection of all units of industrial equipment with the pipelines. In this case, it is not always possible The use of a permanent welded joint is not always possible, therefore, there are various types of weld-free tight joints. FLANGE JOINT COMPONENTS At present, one of the most effective connections used in industrial facilities is a flange joint. This is an airtight connection that provides high structural integrity, consists of two flanges, fasteners (studs or bolts, washers, nuts) and gaskets. An important matter in choosing a set of flanges is tightness. The gasket material must have good elasticity, strength, resistance to the operating temperature conditions and to the media with which direct contact is expected. For flange joints, Villina company uses the following types
