What are the differences between rigid flame retardant pipes and semi rigid flame retardant plastic tubes? Who knows?

Answer:

Hard PVC pipes, PVC resin by adding stabilizer and lubricant additives by kneading, rolling, plasticizing, granulating, extrusion molding processing, mainly used in the construction of wire and cable protection sleeve etc.. Pipe length of 4 meters, the color is generally gray, pipe connections are generally heating, socket and plastic hot air welding, bending must be heated.
Flame retardant plastic corrugated pipe, plasticizer, stabilizer and flame retardant by extrusion molding and made of PVC resin, inner and outer walls are corrugated for wire protection, the general color is yellow, red, white, with a special joint pipe connection with plastic pipe bend after bonding, without heating, bundles the supply of each bundle of 100 meters.
Semi hard plastic tube, Department of PVC resin and plasticizer, stabilizer and other auxiliary agent, by extrusion molding, suitable for electrical and fluid conveying pipe casing, can be used to protect the wire and cable etc. under normal temperature. The tube is supplied with a length of not less than 10 meters. The colors are white, yellow, red, blue, black and ecru. The pipe connections are usually made of plastic sleevesMaterial glue bonding, bending freely, without heating, construction environment temperature 5--45 degrees, in -15--25 degrees, should use cold resistant (yellow) pipe.
Metal flexible pipe, also called prica metal casing, the galvanized steel strip, strip, and electrical paper with a double-layer metal flexible wire, cable protection tube, according to different purposes, different models, including LZ-4, LV-5, LV-5Z and other models, using a dedicated pipeline connecting connector, bending freely, fixed the special fixing clamp, coil, eachGenerally, the diameter of the disc is between 5--50 meters.(1) rigid PVC pipe: PVC resin by adding stabilizer and lubricant additives by kneading, rolling, plasticizing, granulating, extrusion processing, and acid-base, heating bending and cooling is available. The utility model is mainly used for protecting wires, cables, casings, etc.. Pipe length generally 4m/ root, the color is generally gray. Pipe connections are generally heating, spigot and socket connections, and plastic hot air welding. The bends must be heated.(2) rigid flame retardant tube: rigid PVC tube, also known as PVC cold bending pipe, divided into light, medium, heavy. Pipe length is generally 4m/ root, the color is white, pure white, bending needs special bending spring. Pipe connections using special joint insertion connection, the connection with the special surface coating adhesive, sealing interface.(3) semi hard flame tube: also called PVC flame retardant plastic pipe, PVC resin by adding plasticizer, stabilizer and flame retardant agent economy molding, used for wire protection, the general color is yellow, red, white, etc.. The pipe joint is made of a special joint and is covered with plastic adhesive. The pipe is bent freely and needs no heating. It is supplied in bundles of 100 meters each.
