The use of high-quality Q235 cold-rolled strip steel by high-frequency welding in a single molding, double-sided galvanized protection, wall thickness uniformity, weld smooth, high roundness, smooth and burr-free ports. The use of supporting special tools can bend the corner, not change shape, not broken. General fixed length of 4 meters, standard wall thickness of 1.60mm, other types of wall thickness of 1.20mm, light and dark can be used. Specification six: ?16, ?20, ?25, ?32, ?40, ?50.
Second, the main performance of the JDG steel conduit and series of products a technical standard JDG steel conduit series products according to the national standard "electrical installation conduit special requirements" (GB/14823.1-93 GB/13381.1-92) technical standards in line with GB/14823.1-93 GB/13381.1-92), technical standards in line with GB/14823.1-93 GB/13381.1-92). (GB/14823.1-93 GB/13381.1-92) technical standards in line with GB/50258-96, and with reference to the British standard BS4568-1790 technical specifications for metal electrical conduits and fittings, the product was tested by the China Electrical Product Certification Committee Guangzhou Electrical Accessories Inspection Station, the performance indicators have met or exceeded the national standards, has been awarded the "Type Approval Certificate". Type Approval Certificate".
Second, the selection of materials JDG steel conduit and series of products are made of high-quality cold-rolled steel produced by Beijing Shougang Company, precision machining and made of double-sided galvanized, not only beautiful, but also has good anti-corrosion properties.
Three, a wide range of JDG steel conduit open and dark laying can be applied to industrial and civil buildings and municipal pipelines in the wire and cable threading protection, especially for the increasingly respected intelligent office building integrated wiring system.
Four, easy to construct No welding machine and sets of wire equipment, do not need to do across the ground wire, no need to paint, eliminating the traditional welding and sets of wire and other complex construction processes. Simply connect the straight pipe to the pipe, threaded box connector connects the pipe to the junction box, positioning with a special tool to tighten the special screws (broken) and junction box connection with the locking nut can be tightened. Pipe bends with a pipe bender can be bent on-site the corresponding arc.
Fifth, superior performance JDG conduit relative to domestic galvanized pipe, SC pipe and other similar products in the market, in the comprehensive performance has a very significant advantage.
Sixth, project acceptance JDG conduit has formed an industry (CECS) specifications, construction acceptance in accordance with the China Engineering Construction Standardization Association formulated by the CECS120: 2000 socket tightly fixed steel conduit electrical conduit construction and acceptance procedures, project acceptance.
Seven, inexpensive The relatively low price is a prominent advantage of JDG. To 100 meters for the assessment unit and other similar products, JDG has fewer attachments, materials and construction costs and other advantages.
