       The common methods of cast steel threading boxes are straight, three-way, four-way, and curved. It is mainly used for the wiring transition and sealing protection between the wiring pipe and the wiring pipe, between the wall and the wiring pipe. It has the advantages of superior explosion-proof performance, convenient installation and protection. The cast steel thread box housing has three raw materials: cast steel, cast iron and cast aluminum alloy. The outer surface of the cast steel threading box is galvanized; the sealing rubber which is not easy to be incinerated is used for sealing between the body and the cover, and there is no terminal in the box. It is mainly used as a steel pipe wiring or wire and cable for threading and branching. The structure of the cast steel threading box has a straight through, a left cover bend, a right cover bend, a back cover bend, a W-bend, a horizontal tee, a back cover tee, and a horizontal cross. The characteristics of the cast steel threading box:
1, cast steel shell, improve the mechanical joint strength. 2, the appearance of hot dip zinc plus electroplating, electrostatic spraying, electrophoretic paint and other processes, beautiful shape, anti-oxidation effect. 3. Various structural methods, special ferrule coupling type, convenient connection and tight sealing, greatly improving work efficiency and facilitating user's on-site installation. 4, the gasket is sealed with rubber and plastic elastomer, anti-aging, excellent sealing effect. 5, in line with GB3836-2000, IEC60079, GB12476.1-2000, IEC61241 specifications. Applicable scope of cast steel threading box: ◆Applicable to Zone 1 and Zone 2 of explosive gas environment;
◆Applicable to IIA, IIB, IIC explosive gas environment; Applicable to flammable dust environment in Zone 20, Zone 21, Zone 22;
◆ Suitable for environments with temperature group T1 - T6;
