A comprehensive duct company that consistently performs "design," "manufacturing," "sales," and "construction." home privacy policy site map The spiral goby provides high strength. A spiral goby that is characteristic of spiral ducts. This creates high reinforcement and elasticity, and enables strength that can be used for high-speed ducts and smoke exhaust ducts. Due to its excellent workability, it is easy to connect with various fittings. High accuracy is guaranteed by factory production, so no special technology is required to connect with various fittings. There is no loss or leakage due to friction, and it is economical. Since the inner surface is beautifully finished, there is no friction loss and no leakage. Since it is a standard product and lightweight, transportation costs, construction costs, and accessory material costs can be saved. Zinc, stainless steel, PVC coating, galvalume, super dima, flocking ■ Insert joint method Insert the insertion part of the joint into the straight pipe and fix it with 2 to 4 iron plate screws. Furthermore, it is a method of double-wrapping duct tape, aluminum tape, etc. for finishing. Most fittings use this method because they are extremely easy to connect and inexpensive. ■ Flange joint construction method The loose flange method is the standard specification. The flanges used are plate flanges for small diameter sizes (100 to 175Ф) and angle flanges for large diameter sizes (200 to 1600Ф), but both are manufactured according to JIS standards (JISA4412 circular air duct flange dimensions). ■ Mets flange joint construction method After notching the round duct body, just insert the flange. To hang it, just tighten one bolt and the work time will be shortened. ■ Crimp joint construction method Insert directly into the spiral duct without using a fitting nipple. After that, fix it with 2 to 4 iron plate screws, and finish it with duct tape. ■ One-touch fitting method The structure is such that the annular elastic packing moves in the groove, which makes the connection work extremely easy and is a highly airtight connection method with almost no leakage. (* Patent pending) ■ Nipple with don for glass long duct　　 　PAT.800507 ● Attach to the Glaslon Duct Box. ■ Nipple with don　　 　PAT.800507 ● It is easy to fold back, and there is no need to cut with scissors as in the past. ● Since it fits in when used, it can be stored compactly. ■ 　Insert joint　　 PAT.918335 ● As soon as you insert it, it will be caught in the snap and will not come off. ● After inserting, it is completed with a simple seal and tape winding. ● Can be used in many fields depending on the combination. (For flexible duct / chamber box) ■ Spin color ● Since there is a notch, it can be fitted with one touch. ■ Plate thickness 0.5mm ～ 0.8mm　■ Dimensions 100mmФ ～ 500mmФ Opening tube nipple Color nipple Structure and specifications 　Elbow tube 　Single drop 　tube T tube and cross tube 　45 ° Y tube ▲ page top Copyrights ARROW-M CO., LTD.
