For those friends who do not understand the decoration, we must seriously look at the hidden dangers of home renovation that may be missed.

1, hot and cold water pipes mixed
White is a cold water pipe, red is a hot water pipe, and a cold water pipe and a hot water pipe are mixed together.
There are hidden dangers: the expansion and contraction rate of hot and cold water pipes is different. Due to thermal expansion and contraction, the cold water pipes burst and leak.
Standard operation: distinguish hot and cold water pipes according to color and operate strictly.
2, using glue
Normative operation: At present, there is no natural and pollution-free glue on the market. The substitute is 108 glue. But we must look for better brands.
3, no insulation sleeve
During the construction, the wires are directly buried in the wall. The wires are not covered with insulating tubes, and the wire connectors are directly exposed.
There are hidden dangers: This is very unsafe, and may cause short-circuit of the wires due to some reasons, such as the aging of the wires, resulting in wire breakage; at the same time, once the wire is broken, it cannot be changed at all, only the wall knocks on the ground.
Standard operation: The wires must be laid with insulation sleeves on the outside, and the circuit joints should not be exposed on the outside. They should be installed in the line box. No joints are allowed between the distribution boxes.
4, free to change the waterway
In the case that the owner did not understand the decoration, he misled the owner to dismantle the waterway at random and wasted money.
There are hidden dangers: waste of money is only one aspect. Once it is not sealed or lacks pressure during the demolition of the waterway, it will lead to burst of water pipes.
Normative operation: When the pipeline is changed, it will move and it must not be moved when it is not.
5, strong and weak electricity placed together
Typical jerry cuts. Strong power? Such as lighting wire? And weak electricity? Such as telephone lines, network lines? Placed in a tube or box, less shop a pipe, saving time and effort (bathroom dynamics.
There are hidden dangers: There will be interference when making a call or surfing the Internet. At the same time, too much threading in a pipe also creates a risk of fire.
Normative operation: Strong and weak electricity should be routed separately. It is forbidden to share one pipe and one bottom box for strong and weak electricity.
6, the length is not enough without connection accessories
Because the length of the insulating tube is not enough, there is exactly a turn here, no connection fitting is placed, and a section is exposed at the intersection with the junction box.
There are hidden dangers: If you stay for a long time, it may cause leakage due to the aging of the line.
Normal operation: There should be something connected between the nozzle and the junction box.
7, repeat the wiring
A large number of repeated wiring, multi-use materials, waste the owner's financial and material resources.
There are hidden dangers: Once a problem arises in the line, it is difficult to detect it in a layout like "Tian Luo Di Network."
Normative operations: Arranged closely, in the case of no more than 40% of the capacity of the pipe, the same trending line can be worn in a pipe. However, it is necessary to separate strong and weak electricity.
8, the line pipe is damaged by the follow-up project
Typical barbaric construction. After the pipeline was laid, it was slotted on the ground again and the pipeline was laid through.
There are hidden dangers: After you check in, you may find that there is no electricity in a room in your home. You can only detect and re-thread all the wires in your home.
Normative operation: The construction cannot be performed again in the place where the pipeline is laid.
If it is damaged, it is forbidden to wire in the middle when changing lines. When the circuit load is large, the joint of the wire in the threading pipe is easily sparked and a fire occurs.

Stainless Steel V-Profile Press Fittings
The V-profile press pipe system produced by Zheng kang Industrial Co., Ltd is one of the most reasonable, safe and reliable thin-walled Stainless Steel Pipe connection types. It is widely used in direct drinking water, tap water, hot and cold water, heating, gas, fire control and many other fields. Upon introducing German V-profile press technology, combining with our own technical innovation, Zheng kang has developed V-profile press pipe system. V-profile press stainless steel pipe system inherits all the advantages of press fitting system. Meanwhile, it is also featured with a luxurious appearance, high strength, anti-corrosion, anti-pollution and durability, etc.
Principle:
The annular U-shaped groove at the end of Zhengkang stainless steel V-profile press fittings is equipped with an O-ring. When installing, insert a Zhengkang thin-walled stainless steel pipe into the end of pipe fitting and then use a specialized V-profile-press tool to produce hole shrinkage in the U-shaped groove convex, press the sockets of the pipe and fitting into hexagon, to compress the O-ring and guarantee sufficient dealing performance and joint strength.
Advantages :
Sanitation: Not easy to scale after long-term use. The water quality meet relevant sanitary standard.
Anti-corrosion: Pipe overall after solid solution treatment, the surface by pickling passivation, very durable.
High strengh: The comprehensive strength is twice that of galvanized pipe and 3 times of copper pipe.
Light weight: The weight is 1/3 that of galvanized pipe, which is particularly suitable for high-rise buildings.
Low conductivity: Low thermal conductivity, 1/25 that of copper pipe and 1/4 that of steel tube. The thermal expansion is slow.
Environmental protection: No pollutants in construction sites. No pollution to the environment.
Parameters:
Material: Stailess steel sus304, sus316 and sus316l. Can be selected pursuant to difference service conditions.
Pressure: Working pressure no more than 1.6 mpa.
Temperature: Working temperature-20--110 degree centigrade
Seal: O-ring id made of butyl rubber, which is resistant to hot water and aging. It proves safe and non-toxic in hygiene tests and can be used for drinking water and tap water, etc.
Fitting standard:DIN, JIS,DVGW
O-Ring Seal material: EPDM (black), HNBR,NBR
Payment term: TT, L/C price term: FOB,CIF,CNF.
Anneal: all stainless steel pipe fittings are annealed in inert gases before packing.
Stainless steel press fitting is the best connection for thin multiplayer all stainless steel pipe, PE(X)-Al-PE(X) multiplayer pipe and SS-PE composite pipe. Versatility of press fittings can widely use in potable water system, water supply and drainage, heating and cooling water circulation system, fire services sprinkler system, gas system and etc. Easy and fast installation with simple press tools can save time and improve job productivity and profitability.
