"PVC

Can the plastic pipe withstand high temperature

"

, peda small make up here to give you some explanation, from

PVC

Some basic information of plastic pipe, such as characteristics, application range, etc

Solution:

PVC -u

Plastic pipe is composed of amorphous thermoplastic resin made by polymerization of vinyl chloride monomer and certain additives (such as stabilizer, lubricant, filler, etc.).

PVC -u

In addition to additives, the plastic pipe was also modified by blending with other resins, so that it has obvious practical value. These resins have

CPVC

,

PE

,

ABS.

,

EVA

,

MBS

And so on.

UPVC

The melt viscosity is high and the fluidity is poor. Even if the injection pressure and melt temperature are increased, the fluidity does not change much. In addition, the resin molding temperature and thermal decomposition temperature is very close, the temperature range of molding is very narrow, is a difficult to shape the material.

 

 

Features:

PVC -u

Plastic pipe bending performance, good chemical corrosion resistance, mechanical strength, aging resistance, temperature resistance.

 

 

Bearing capacity:

PVC -u

The plastic pipe can bear the weight of the foot without breaking.

 

 

PVC -u

Plastic pipe application field: wire bushing, decorative bushing, suitable for liquid and oil conveying, power line protection, automotive wire harness protection, machine tools, automation instruments, etc.

 

 

PVC -u

Plastic pipes are light in weight and easy to handle

PVC -u

Plastic pipe material light, proportion only iron pipe

1/5

, handling, loading and unloading, construction convenience, can save construction costs.

PVC -u

Plastic pipe has excellent corrosion resistance and drug resistance

PVC -u

Plastic pipe has excellent acid resistance, alkali resistance, corrosion resistance, suitable for chemical industry, wastewater drainage, sanitary sewer and other USES. Low fluid resistance

PVC

The wall surface of the tube is smooth and the resistance to the fluid is small

0.009

, lower than other pipe materials, in the case of the same diameter, the flow is large, and does not adhere to scale.

PVC -u

Plastic pipe has great mechanical strength

PVC

The pipe has good water pressure resistance, impact resistance and so on. At room temperature,

PVC -u

Plastic pipe is suitable for piping engineering under various conditions.

 

 

Good electrical insulation

PVC -u

Plastic pipe has excellent electrical insulation, suitable for wire, cable conduit, can be widely used in telecommunications, power distribution and construction wire piping. Does not affect water quality

PVC

The result of dissolving test proves that the pipe has no effect on the water quality

"

Red water

"

Is the common pipe material for water supply. Good water solubility

PVC -u

Plastic pipe, whether by looping socket or

TS

The combination of socket and mouth has good water tightness. Although it has water pressure water distribution pipe for many years, it will not cause water leakage. Construction is simple and easy

PVC -u

Plastic pipe construction is quick and easy, and construction cost is low.

 

 

PVC -u

Plastic pipe

 

 

PVC - U

As a drainage pipe, due to its own characteristics, the indoor continuous drainage temperature shall not be greater than

40

℃

, and the instantaneous drainage temperature should not be greater than

80

℃

 

. This point is often ignored, long-term use of the process will lead to pipe joint leakage phenomenon, especially in the college laboratory building part of the biochemical laboratory often appear this problem. And the solution can only be replaced by other metal drainage pipe. At the same time a

PVC

Pipe installation should avoid layout in the heat source accessories, this point in the kitchen drain pipe installation should pay special attention to, must ensure the distance between the drain pipe and the cooker, if not avoid should take heat insulation measures.

 

 

PVC - U

When drain pipes are used in high-rise buildings. Some engineers did not follow the technical regulations to take measures to prevent fire throughout. The correct practice is: according to the technical regulations, the riser is provided and its pipe diameter is greater than or equal to

110 mm ~ l, - J

, at the riser crossing the floor. Measures should be taken to prevent the spread of fire

;

Pipe diameter greater than or equal to

110 mill

When the horizontal branch pipe of open surface drainage is connected to the pipe well and the vertical pipe inside the pipe, measures shall be taken to prevent the fire from penetrating through the wall of the pipe well and the pipe armhole. Horizontal trunk should not cross the fire partition wall and firewall

;

When it is necessary to cross the pipe, it should be on both sides of the pipe crossing the wall to take measures to prevent the flame through, such as waterproof sleeve, fire ring, etc.
