PVC pipe is the drain pipe, the installation method indoor and outdoor is a little different, the interior directly depends on the corner open hole to install and then fixed well waterproof. The outside is a special card mouth, one is fixed on the external wall with the expansion screw, the other end is the jammed pipe of PVC, and the joint is connected with the PVC glue directly. Use a live knot if you want to move.
Installation method of drainage pipe:
(1) PVC - U core layer foaming drainage pipe, adhesive and flange interface.
(2) according to the drawing requirements, according to the actual situation, the size is measured according to the reserved port, and the processing sketch is drawn.
(3) make the pipe size according to the sketch and break the pipe. Fracture will flush with file or scraper to remove impalement fracture inside and outside, outside edge Angle of file out of 15 ℃.
(4) adhesive, deal with socket inserted into the test first, not all inserts, generally for 3/4 of the socket depth, test qualified after, need to use cotton cloth to socket adhesive parts of moisture, dust, wipe clean. If there is oil, you need acetone. With brush daub binder, first daub the daub after socket socket, then force vertically inserted, inserted into the adhesive, it will be slightly rotated socket, eli dope uniform distribution, firm bonding of about 30 to 60 min.
(5) plastic drainage pipe installation, temporary hanging, galvanized iron wire can be used for preliminary installation, adjustment to jilt mouth coordinates, elevation, slope position, pipes, comply with the design requirements of adhesive, and mouth coordinates, elevation gradient correction in a timely manner. After curing, install the fixed supporting parts but should not tighten. The rubber gasket must be placed in the contact area of the tube when the metal support is used.
(6) the minimum floor and the highest level of the drainage riser should be set to the inspection port, and the center of the inspection mouth is 1.0 meters from the ground.
(7) after the pipe is installed, the pipe hole should be plugged in time. The model shall be blocked in accordance with the specification. After installation, the pipe shall not be used for climbing or borrowing. Horizontal dry pipe slope of domestic sewage (PVC - U) :
The PVC - U drainpipe is widely used in China because of its wide source, so users should pay special attention when choosing.
1, according to the present the most common white PVC - U pipes, color is ivory and uniform, both inside and outside wall are relatively smooth, but a little tough as well, and more time PVC -u drain color or white, or some yellow, and a hard, some uneven color, some special smooth outer wall, the wall is rough, sometimes have a needle or holes.
2. The toughness of PVC - U drainpipe is a key indicator. Ductile big tube when we saw it into a narrow strip, try to fold 180 & deg; If it breaks, it shows that the toughness is poor and the brittleness is large; If it's hard to break, it's tough to break, and the more you need to break it, the harder it is, the strength is good, and the toughness is generally good. Finally, the stubble (except the stubble) is observed. The more exquisite the stubble, the better the homogenization, strength and toughness of the pipe.
3. The impact of PVC - U drainpipe can also be used to make macro general judgment. Can choose room temperature close to 20 ℃ environment, saw into 200 mm long section (tube) to 110 mm, pounding the hammer, good steel tubes, with human hard to break at a time. The thicker the pipe, the greater the bearing capacity.
4. Conditional users can make the pipe material into a dumbbell shape, with a width of 6mm in the parallel narrow width, and the tensile strength of 5mm/min tension speed, which is more than 10MPa. The longer the stretch, the better.
5. When users choose PVC - U drainpipes, they should go to reputable distribution points to select large and well-known enterprises, or to buy direct sales of well-known brands. After our preliminary investigation, the sales of the roadside small distribution of the miscellaneous PVC - U pipe qualified rate of less than 20%.
