Who has the wall thickness requirements for PVC drainage fittings?

PVC drainage pipe wall thickness requirements are PVC drainage pipe outer diameter is not the same, the commonly used DN75 nominal wall thickness is, DN110, DN160, specifically according to GB T, reference standard "building drainage with hard polyvinyl chloride (PVC U) pipe installation", commonly used PVC drainage pipe specifications are mainly based on the nominal outer diameter, respectively, 32mm, 40mm, 50mm, 75mm, 90mm, 110mm, 125mm, 160mm, 200mm, 250mm, 315mm, 400mm, 500mm, most PVC drainage pipe specifications have a certain gap, which is normal. The length of PVC-U pipes is generally 4m or 6m, and other lengths are determined by the negotiation between the supply and demand parties.

The nominal outer diameters of PVC drain pipes are: 32mm PVC drain pipe, 40mm PVC drain pipe, 50mm PVC drain pipe, 75mm PVC drain pipe, 90mm PVC drain pipe, 110mm PVC drain pipe.

125mm pvc drain, 160mm pvc drain, 180mm pvc drain, 200mm pvc drain, 250mm pvc drain, 315mm pvc drain.

According to the national standard for wall thickness of PVC drainage pipes, "Installation of Rigid Polyvinyl Chloride (PVC U) Pipes for Building Drainage" (10S406).

Provisions: The conventional specifications of commonly used PVC pipe drainage pipes are as follows: the nominal outer diameters are: 32mm, 40mm, 50mm, 75mm, 90mm, 110mm, 125mm, 160mm, 180, 200mm, 250mm, 315mm, 400mm, 500mm, 630mm, etc. The length of PVC-U pipes is generally 4m or 6m, and other lengths are negotiated by both supply and demand.

Are you sure. PVC pipe drain pipe.

It is based on sanitary polyvinyl chloride (PVC) resin as the main raw material, adding an appropriate amount of stabilizer, lubricant, filler, and color enhancer.

After plastic extruder extrusion molding and injection molding machine injection molding, it is completed through cooling, curing, shaping, inspection, packaging and other processes.

Production of pipes and fittings.

The national standard specifications are: 50*, 75*, 110*, 160* regular manufacturers will produce according to the national standard, and the wall thickness deviation will only be more, not allowed to be less, as shown in the following table:

There is a relationship between the wall thickness and the pipe diameter, and the wall of the pipe with a large diameter is naturally thicker, and the wall thickness of the same pipe diameter of a well-known brand is relatively thicker than that of the ordinary one.

PVC drainage pipes go through cooling, curing, shaping, inspection, packaging and other processes to complete the production of pipes and pipe fittings. It has excellent physical and chemical properties, chemical corrosion resistance, high impact strength, low fluid resistance, 30% higher flow rate than cast iron pipes of the same caliber, aging resistance, long service life, and a service life of not less than 50 years, which is an ideal material for building water supply and drainage.

U-PVC Drainage Pipe National Standard Wall Thickness.

Diameter: Wall thickness.

16:i25;63;u-pvc

Also known as hard PVC or PVCU, it is an amorphous thermoplastic resin made of vinyl chloride monomer through polymerization reaction and certain additives (such as stabilizers, lubricants, fillers, etc.). In addition to additives, the method of blending and modification with other resins is also adopted, which makes it have obvious practical value. These resins are CPVC, PE, ABS, EVA, MBS, etc.

The melt viscosity of UPVC is high and the fluidity is poor, and even if the injection pressure and melt temperature are increased, the fluidity does not change much. In addition, the molding temperature of resin is close to the thermal decomposition temperature, and the temperature range that can be molded is narrow, making it a difficult material to mold.

Feature 1, light weight, convenient handling, loading and unloading

PVC pipe material is very light, easy to handle, easy to build, and can save labor.

2. Excellent chemical resistance.

PVC pipes have excellent acid resistance, alkali resistance and corrosion resistance, which is very suitable for the use of chemical industry.

3. Low fluid resistance.

The wall surface of PVC pipe is smooth, the resistance to the fluid is small, its roughness coefficient is only lower, than other pipes, and the pipe diameter can be reduced under the same flow rate.

4. High mechanical strength.

PVC pipes have excellent water pressure resistance, external pressure resistance, impact resistance, etc., and are suitable for piping projects under various conditions.

5. Good electrical insulation.

PVC pipes have superior electrical insulation, and are suitable for conduit of wires and cables, as well as wire piping on buildings.

6. It does not affect water quality.

PVC pipes have been confirmed by dissolution tests and do not affect water quality, making them the best pipes for tap water piping.

7. Simple construction.

The joint construction of PVC pipes is fast and easy, so the construction cost is low.

There is a relationship between the wall thickness and the pipe diameter, and the wall of the pipe with a large pipe diameter is naturally thicker, of course, relatively speaking, the wall thickness of the same pipe diameter of a well-known brand is thicker than that of the ordinary one.

According to the GB T building drainage hard PVC pipe fittings standard, the wall thickness of the main body of PVC drainage pipe fittings shall not be less than the wall thickness of the pipe of the same specification, and the wall thickness of PVC drainage pipe is shown in the following figure:

PVC pipe drain pipe is made of sanitary polyvinyl chloride (PVC) resin as the main raw material, adding an appropriate amount of stabilizer, lubricant, filler, color enhancer, etc., through plastic extruder extrusion molding and injection molding machine injection molding, through cooling, curing, shaping, inspection, packaging and other processes to complete the production of pipes and pipe fittings. The conventional specifications of commonly used PVC pipe drainage pipes are as follows: The nominal outer diameters are:

32mm, 40mm, 50mm, 75mm, 90mm, 110mm, 125mm, 160mm, 180, 200mm, 250mm, 315mm, 400mm, 500mm, 630mm, etc. The length of PVC-U pipes is generally 4m or 6m, and other lengths are determined by negotiation between the supply and demand parties.
