How to use Water service tube (VP) and electric wire tube (VE)
There are various kinds of hard vinyl chloride pipes. Electric wire tube (VE) might sometimes be used though water service tube (VP) is usually used for the drain construction of the air conditioner. When it doesn't know the size to connect these mutually, it doesn't become it.
When the air conditioner of the ceiling hanging type is installed, the drain early piping of the vinyl chloride pipe might be done. VE16 and a normal pipe bend were laid as a drain drainpipe at electrical work this time.
Well, how even the connection point of the drain drain of the air conditioner had been laid at this time worried. Then, the interconnection of the water service tube and the electric wire tube was examined and I want to record.
Size of water service tube (VP) often used and electric wire tube (VE)
| Water service tube(VP) | Electric wire tube(VE) | The unit is [mm] and an other size. | ||||||
|---|---|---|---|---|---|---|---|---|
| Outside diameter |
Thickness | Inside diameter |
Outside diameter |
Thickness | Inside diameter |

| VP13 | 18 | 2.5 | 13 | VE14 | 18 | 2.0 | 14 | The outside diameter is the same as VP13 and VE14. |
| VP16 | 22 | 3.0 | 16 | VE16 | 22 | 2.0 | 18 | The outside diameter is the same as VP16 and VE16. |
| VP20 | 26 | 3.0 | 20 | VE22 | 26 | 2.0 | 22 | The outside diameter is the same as VP20 and VE22. |
| VP25 | 32 | 3.5 | 25 | VE28 | 34 | 3.0 | 28 | |
| VP30 | 38 | 3.5 | 31 | VE36 | 42 | 3.5 | 35 | |
- It is understood that the numerical value of the calling diameter from this table to water service tube VP and electric wire tube VE is almost an inside diameter. (The inside diameter of VE36 is 35mm a little ..inside diameter of VP30.. ..31mm.. ..inside diameter of VE16.. ..18mm.. different from the numerical value of the port diameter exceptionally. )
- There is the one of a heatproof hard vinyl chloride of the coffee brown named the one of a navy blue named HIVP impact resistance hard vinyl chloride and HTVP besides hard vinyl chloride VP of the mouse color (gray), too.
- Use the electric wire tube provided in Electrical Appliances and Materials Safety Law is needless to say to the piping of the electric equipment construction. The VP tube cannot be used for electrical work.
- It is necessary to use the tube that is admitted in the piping of the water fixture construction for water service and sold. The electric wire tube cannot be used as a water service tube.
- This has only VU40 or more though there is a hard vinyl chloride tube of the Japanese pampas grass meat of VU tube used for the drain equipment construction. The VP tube is the same as the outside diameter.
Using for the drainpipe, using the water service tube and the electric wire tube
The outside diameter size is quite the same as "VP13 and VE14", "VP16 and VE16", and "VP20 and VE22" from the table above. If an elbow, a socket, and a normal pipe bend are used in a word, it is possible to connect it mutually.
Moreover, it can be easily done to convert the thickness of the drain drainpipe freely if the strange appearance socket of VP is used and to use it.
When you use a normal pipe bend
If the strange appearance socket is not used and a normal pipe bend of the electric wire tube is used, it becomes it as well as the outside diameter of one high rank because the thickness of a normal pipe bend of VE14, VE16, and VE22 is 2mm.
In a word, the outside diameter of a normal pipe bend of VE14 (18mm in the outside diameter) becomes it as well as outside diameter (22mm) of VE16(VP16). The socket of VP16 can be used as it is.
The outside diameter of a normal pipe bend of VE16 (22mm in the outside diameter) becomes similar as well as outside diameter (26mm) of VE22(VP20). The socket of VP20 can be used as it is.
