The BSZ unit is used to distribute current from a single common input to one or more outputs, providing simultaneous protection of several underground steel pipelines (or structures) from a single cathodic protection station (CPS). Its purpose is to eliminate mutual potential interference between adjacent pipelines by accurately distributing and maintaining the required protective potential on each object, ensuring effective corrosion protection.
A single-use crucible mold is a product made of refractory material, filled with a thermite mixture and manufactured as a disposable casting mold.
It is intended for welding steel or copper cathodic protection and drainage leads of electrochemical protection (ECP) systems with a diameter of 3–8 mm to steel main pipelines with a nominal diameter from DN 100 to DN 1400, strength class up to K65 inclusive, and a wall thickness of at least 5.0 mm. It is recommended for use in the gas and oil industry during construction, operation, and repair of pipelines.
