The main purpose of PVC electrical fittings pipe fittings:

pvc electrical fittings has excellent performance of strongstress-resistant, corrosion-resistant, anti-moth, flame retardant, insulation and so on. In the area of construction, it also has advantage of light weight, easy to cut, easy to bend, installation flexibility, quick construction and so on. Pvc retardant electrical casing has extensive use in concrete, floor or between walls as electrical conduit, underground pipe can also be used as general wiring conduit pipe Ming and telecommunications, network cabling pipe. PVC electrical accessories, electrical conduit has good bending performance. PVC electrical conduit is a kind of PVC as the main raw material, add some special resist, by extrusion of a pipe, commonly known as PVC electrical conduit retardant wire and pipe, tube and rodents. Retardant electrical casing production process is now usually carried out in strict accordance with JG3050-1998 production. Retardant electrical casing has models of Φ16 ~ Φ63mm, specifications are 205 (light), 305 (medium), 405 (heavy).

    Retardant electrical casing has a variety of performance characteristics, as an electrical conduit, its insulation performance is very good, with good anti-current breakdown voltage capability, generally able to withstand 25 kV voltage without breakdown, and it is no live dangerous. Retardant electrical casing also has a very good impact resistance, it can withstand the pressure, can be concealed within the concrete, no fear of the damage of pressure and shocks. Retardant electrical conduit also has good fireproof performance, because of high oxygen index, it is hard to make flame. If leave the flame, it will instantly self-extinguishing. Retardant electrical casing also has some moisture, acid corrosion properties, and will not cause corrosion when together with other materials.

Retardant electrical casing has a smell which pest does not like, thus avoiding the problem of pest damage bite. It has good flexible performance, with good bending resistance, we only need to insert a spring in a fire-retardant electrical casing, without heating, it can be blended with hand. Now fire-retardant electrical conduit can be used in the building or underground electrical installation, and its use is in extension.

PVC electrical accessories - Conduit Profile

Pvc electrical accessories is the abbreviation ofpolyvinylchloride,polyvinylchlorideproducts include common pipes, soles, toys, doors, stationery,polyvinylchloridepipe is an common products ofpolyvinylchloride. Althoughpolyvinylchloridehas features of stable, hard to be acid corrosion, high heat tolerant, its development are hindered by cost barriers, industrial policy barriers, scale barriers, financial barriers.

Vinyl chloride (PYC) resin as the main raw material, wire pipe products, because of its role in fire resistant,polyvinylchlorideis widely used in wire and fiber. Also often used to make gloves.

Polyvinylchloridecan be made from ethylene, chlorine and the catalyst.

PVC electrical conduit fittings are cheap, widely used. Polyvinyl chloride resin is white or pale yellow powder. Different additives can be added according to different use,Polyvinylchloridecan present different physical and mechanical properties. a variety of hard, soft and transparent products can be made if adding an appropriate amount of plasticizer in PVC resin.

Convenience of PVC casing accessories in construction

PVC electrical accessories casing is very light, usually 1/10 of pressure tube, 1/6 of steel, and easy for transportation and installation. PVC casing construction is very convenient. Conduit consist of connectors, waterproof seals, brackets and other components. Reasonable design, easy construction, no need to pour concrete protective layer. Stent use modular connection, easy to install, and can greatly shorten the construction period, non-radioactive carcinogens, has significant economic and social benefits.
    

Good corrosion resistance is a large characteristic of PVC casing, PVC casing material has excellent power acid, alkali, salt and other chemical solvents, corrosion, no case of oil cracking, can adapt to various soil and work environment. High strength, heat resistance, long service life. Compared to traditional forms of asbestos and cement , it with a flexible, high temperature, easy to break and aging, long life, non-radioactive contamination and other characteristics, its strength can replac steel, and overcome corrosion and avoid the damage caused by  high temperature of single-core cable.

Used as an electric pipe, of course, good insulating properties is indispensable.PVC casing itself retardant power, put out away from the fire, high volume resistivity, excellent insulation properties. The main ingredient of PVC power casing ispolyvinylchloride, while adding other ingredients to enhance its heat resistance, toughness, ductility. This table top layer is painted, the main ingredient in the middle ispolyvinylchloride, the lower is the adhesive-backed. It is now loved by the world, and is quite popular and is also widely used as a synthetic material.

Maintenance treatment of PVC electrical wire and pipe fittings

Maintenance of Pvc conduit fittings are diverse, and we can choose according to the actual situation.

    Due to external force causes small area damage, cracks of Pvc electrical conduit fittings, and if in the same physical properties, adhesion treatment is available. Roughen the damaged parts, cut the same diameter of the pipe, covering an area larger than the damaged parts, clean and roughen the inside of seleced pipe, apply adhesive chip on damaged parts of and also the selected pipe, cover the repairing tube sheet to the damaged area, and fasten with a pipe clamp or wire. Pvc conduit can also use welding repair method, but be aware that welding parts is dry, meanwhile remove dust, oil and other oils on its surface, the adhesive must be cleaned before welding.

When need to replac damaged pipe, this damage part should be amputated, replac new pipe, specification overΦ160 can be use on-site hot socket repair method: lift up both ends of the pipeline which is sawed off , both sides make chamfered. The length of replac tube should be segment length plus insertion length on both ends, heat the replaced pipe on both ends,then insert into the original pipe, and put into the ditch, then water can go through after cooling.

Flange quick docking, amputate pvc pipes wher need to be replaced break both ends, take four plate bearing joints, substitute tube section, the four bearing plate joints are set into for ends, make flange joint of the four ends. Plastic quick coupling connection, saw expansion or damaged parts, set into a loose flange and a rubber ring at both ends. lift one end of the broken pipe, set into flanged casing, pushed back flanged casing to an equal distance from both ends of the broken pipe, fasten the loose flange and flange casing with bolt.
