Stainless steel water pipes is a common water pipe. There are many kinds,
According to different production methods, stainless steel water pipes can be divided into seamless pipe and welded pipes
According to the wall thickness classification of stainless steel water pipes, it can be divided into thin-wall steel pipe and thick wall steelAccording to the material classification of stainless steel water pipe, it can be divided into 304 stainless steel water pipe, 316 stainless steel water pipes, etc.
① Seamless pipe: seamless pipe includes cold drawn pipe, extruded pipe, cold rolled pipe and other types, which can be used as a pipe for conveying fluid.
② Welded pipe: welded pipe can be divided into gas shielded welded pipe, arc welded pipe, resistance welded pipe, straight seam welded pipe, spiral welded pipe and other types. The strength of welded pipe is higher than that of seamless pipe
Low, but the production is simple and there are many specifications.
① Thin wall steel pipe: the ratio of outer diameter to wall thickness of thin wall steel pipe is greater than 20, which can be used to transport general fluids.
② Thick walled steel pipe: the ratio of outer diameter to wall thickness of thick walled steel pipe is less than 20. It can be used for liquid and gas transportation and structural piling.
① 304 stainless steel water pipe: 304 stainless steel water pipe has the advantages of environmental protection, sanitation, wear resistance, low temperature resistance, good thermal expansion performance and thermal insulation performance.
② 316 stainless steel water pipe: 316 stainless steel water pipe is corrosion-resistant, high temperature resistant and has good welding performance.
The commonly used dimensions of domestic stainless steel water pipes include DN15 (4-inch pipe), DN20 (6-inch pipe), DN25 (1-inch pipe), DN32 (1-inch 2-pipe), Dn40 (pay inch half pipe), DN50 (2-inch pipe), DN65 (3-inch pipe), DN80 (4-inch pipe), DN100 (5-inch pipe), DN125 (6-inch pipe), DN150 (8-inch pipe), DN200 (8-pipe), etc.
Connection method of stainless steel water pipes
The clamping pressure connection method can be divided into single clamping pressure and double clamping pressure, in which the stability of double clamping pressure is better, and the stainless steel water pipe connected by clamping pressure is easy to install and operate
Operation and good sealing performance.
The expanding ring connection adopts radial contraction external force (hydraulic pliers) to clamp the pipe fitting on the pipe, and the water stop through the wide-band rubber sealing ring. The expanding ring connection is detachable
But the sealing effect is lower than that of compression connection.
The welding connection adopts the hot-melt process to weld the two connectors, which has high connection strength, but it has high technical requirements for the operation of the welding function, and the quality is difficult at the same time
The self-locking connection can be used for the connection of small-diameter plastic hose. It is simple and fast to install, but it is easy to loosen and leak, and the sealing performance is poor.
Stainless steel water pipes are green, environment-friendly and healthy, and the pipe material is relatively stable. They will not accumulate scale and are not easy to be contaminated by bacteria after long-term use. There is no need to worry about the impact of water quality ring.
Stainless steel water pipes have excellent corrosion resistance, high temperature resistance and high pressure resistance, long service life and can be used for a long time, reducing the trouble of replacing pipes,no special maintenance is required in the later stage.
The water resistance of stainless steel water pipe is small, which can reduce the transmission cost of water. At the same time, because the thermal expansion coefficient of stainless steel water pipe is low, it can also reduce the heat loss,very energy-saving and environmental protection.
For ordinary families, the price of stainless steel water pipes is still relatively high. If the whole house is paved with stainless steel water pipes, the cost is still high.
The material strength of stainless steel water pipe is relatively hard, so the on-site cutting process will be more difficult, and the requirements for construction technology are high, which can be well completed only by skilled workers.
PPR water pipe is what we usually call plastic water pipe. The main material of this kind of water pipe is modified plastic propylene, while the main material of stainless steel water pipe is stainless steel
In terms of safety and sanitary performance, stainless steel water pipes must be better.
Moreover, the installation of stainless steel water pipe is simple, environmentally friendly and healthy. From the perspective of users, it is certainly better to use stainless steel water pipe. However, the price of stainless steel water pipe is much more expensive than PPR water pipe, so from the perspective of developers, they may prefer to use plastic water pipe.
The price of stainless steel pipes will vary according to the material and brand of the products. Generally speaking, the price of thick wall steel pipes is a little higher than that of thin-wall steel pipes, while the price of 316 stainless steel pipes with better high temperature resistance is a little higher than that of 304 stainless steel pipes.
The specific price still needs to be inquired in the local building materials market. Generally speaking, The price of ordinary stainless steel water pipe is about 140-180 yuan / meter.
First, cut the stainless steel water pipe into appropriate size with a tool knife.
Polish the burrs at both ends of the stainless steel water pipe with sanding paper to prevent scratching the sealing ring.
Mark the installation position with a marker to indicate the insertion depth of stainless steel water pipe.
Align the two orifices of the stainless steel water pipe, insert them and tighten them with tools.
The crimped stainless steel water pipe shall be wrapped with two layers of polyethylene tape or vinyl chloride tape for anti-corrosion treatment.
Finally, check whether the pipeline is clamped in place and whether there is water leakage.
