Derui Company is a professional manufacturer and supplier of sacrificial anodes, epoxy resin coated steel bars, marine engineering environmental protection anti-corrosion materials, cathodic protection technology and engineering design and installation, technical services.
Thermite welding (also known as thermit welding) is the use of metal oxide and metal aluminum exothermic reaction between the superheated molten metal to heat the metal and achieve welding method, mainly used in gas, oil, natural gas chemical steel pipe cathodic protection and power cable welding.
DERUI produces various specifications of junction boxes suitable for land or Marine environments. The explosion-proof rating is ATEX, Exe, Exd. The shell includes stainless steel, steel plate, cast aluminum and other non-metallic materials, etc., and can be installed internally, shunt, variable resistor, ammeter and other electronic components.
Cable Bond Boxhe insulated junction box is a new type of cable and cable connection box, which is connected between multiple cables at the project site through a specific mold and then poured into epoxy for sealing, playing the role of insulation protection, and the site operation is simple, safe and efficient.
In the construction of cathodic protection site, it is inevitable to destroy the coating of pipes and other structures, such as welded cables, etc., generally use repair pieces, repair rods, and hot melt adhesive to repair the damage.
Isolation joints are mainly used between gas transmission and distribution pipelines and gas pressure regulation, metering, storage and other equipment, and their main function is to isolate each section of gas transmission and distribution pipelines, equipment and pipelines, protect them from chemical corrosion, and extend the service life of pipelines and equipment.
The polarization probe is to assemble the reference electrode and the polarization test piece that simulates the damage point of the anti-corrosion layer, buried in the soil, and measure the electrical potential of the test fragment to judge the protection state of the pipeline. The polarization probe is divided into saturated copper sulfate reference polarization probe and zinc reference polarization probe.
Derui Corrosion-Resistant Material Co., Ltd. also provides supporting facilities related to cathodic protection, such as spark gap, polarization test plate, grounding battery, corrosion probe, heat shrink tape, cold wrap tape, heat wrap tape, heat shrink sleeve, anticorrosive tape and so on.
