What tools do I need for plastic hose and steel pipe installation and how to use them?

Hose installation generally uses a wallpaper knife to cut the length, and of course a ruler must be prepared for pipe installation. The steel pipe should be prepared with a pipe wrench, a large (200) small 100 wrench, and an ink line (optional).Pipe cutter (very heavy) and plate teeth, raw material belt.

The above is not welded. It is for wire jointing. Steel Pipe:

Measure the size and clamp the pipe with the vise on the pipe shelf. Cut it with a cutter, cover the two ends of the pipe with the plate teeth, and wrap the raw material clockwise on the silk teeth. Screw on the corresponding fittings.

Measure the length of another tube and repeat the above steps. Then it's time to install. It's a lot of energy.

Remember.

1 Tee (tee) installation.

The positive tee (positive tee) is loaded into the connection between the riser and the transverse branch pipe, resulting in the formation of a water tongue flow at the junction, the water flow of the transverse branch pipe is not smooth, the air pressure of the drainage system fluctuates greatly, the water seal of the sanitary appliances is easy to be destroyed, and the toxic and harmful gases in the drainage pipe invade the room, causing environmental pollution. The correct thing to do is that 45 should be installed here. Diagonal tee or smooth tee.

2. The connection between the drainage riser and the drainage outlet pipe connecting pipe fittings.

In some high-rise buildings, designers often need to enlarge the pipe diameter of the outlet pipe by one when designing, and often use two 45 pipes with the same diameter as the riser at the bottom of the riser during construction. The elbow is connected, and then the reducer is changed on the discharge pipe, which is often easy to form an air lock at the connecting reducer, causing the pipeline to be blocked and affecting the drainage of the pipeline. The correct way is to connect the elbow after enlargement with a reducer at the bottom of the riser, and the reducer is an eccentric reducer, and the eccentric side is on the inner circle side of the turn.

3 Installation of expansion joints.

Due to the large linear expansion of PVC-U drainage pipe, the expansion and contraction caused by temperature change is large. In the installation of drainage risers. It is necessary to install the expansion joint, but how to install it and where to install it, the construction unit is not.

It's clear. At the same time, the expansion joint is often not installed correctly or not installed on the transverse branch pipe during construction, and according to the requirements of the specification, when the straight section without confluence pipe fittings on the drainage transverse branch pipe, the main pipe, the appliance ventilation pipe, the circumferential ventilation pipe and the converging ventilation pipe is greater than 2 m, the expansion joint should be arranged, and the drainage transverse branch pipe should be provided with a special expansion joint. And the maximum spacing between telescopic nodes shall not be greater than 4 m.

1) Quantity. When the floor height is less than 4 m, the riser should be provided with an expansion joint on each floor; When the floor height is greater than 4 m, it should be determined according to the design expansion amount, and the design expansion capacity should not be greater than the maximum allowable expansion and contraction amount of the expansion joint.

2) Location. The construction unit often thinks that as long as there is an expansion joint on the drainage pipe, it can meet the requirements of the specification, and even the expansion joint is regarded as a connecting pipe fitting, resulting in joint leakage and water seepage, the correct approach is that the expansion joint socket should be set up in the direction of water flow, and the expansion joint should be arranged under the water flow confluence pipe fitting when the drainage branch pipe is connected to the riser below the floor slab; When the drainage branch pipe is connected to the riser above the floor slab, the expansion joint should be arranged on the water flow confluence pipe fitting; When the drainage branch pipe is connected to the floor slab at the same time, it is advisable to place the expansion joint in the middle of the floor. At the same time, when the riser crosses the floor for a fixed support, the expansion joint shall not be fixed, and when the shrinkage joint is a fixed support, the riser shall not be fixed for crossing the floor.

The expansion joint on the transverse pipe should be placed at the upstream end of the water flow confluence pipe fitting.

3. Excellent corrosion resistance, chemical resistance chain and quality: PVC-U pipe has excellent acid resistance, alkali resistance, corrosion resistance, is not affected by moisture and soil pH, and does not need any anti-corrosion treatment when laying pipes.

4. Good watertightness: The installation of PVC-U pipes, regardless of whether they are connected by adhesives or rubber rings, has good watertightness.

5. Anti-bite: PVC-U tube is not a source of nutrition, so it will not be eroded by rodents. According to a trial conducted by the National Health** in Michigan, rats do not bite PVC-U pipes.

6. Performance test: curing time, shrinkage, splitting strength, tensile properties, peeling strength, thermal stability, application period, storage period, release of harmful substances.

How do you attach the hose?

1. First of all, confirm that the pipe is leaking and dripping. You can use a dry rag and dry one of the hoses first, the main surface is free of water. Then I will go and see later, if there is still water, it means that there is something wrong with this root; If there is no water, there is something wrong with the other one.

2. If the inlet pipe of the faucet is broken. Let's choose this kind of pipe. One end is big, the other end is small, and the small end is to be screwed into the faucet.

3. Then remove the faucet. The faucet is generally fixed to the sink or basin with screws, find the fixed nut, press it and it's OK. Then you can loosely unscrew the other end of the broken hose.
