Healthy materials with extremely high requirements for safety and cleanliness

　　Advantages such as cleanliness, durability, economy and environmental friendliness

　　Stainless steel water pipes are known as "truly green pipes".

　　Stainless steel water pipeZGood pipes for direct drinking water delivery

　　Stainless steel water pipe, yesZGood pipes for direct drinking water delivery. It has the characteristic of a very low leakage rate and can save precious water resources. The leakage rate of water pipes in the 1980s was17%After switching to stainless steel pipes, the leakage rate dropped7%. The water supply system was damaged in the earthquake, but the stainless steel water pipe system remained intact. In addition, compared with copper water pipes, stainless steel water pipes have better water permeability and do not corrode under high flow rates. Its heat preservation property is also that of copper pipes24Double.

　　Stainless steel is a healthy material that can be implanted in the human body. Therefore, for water supply pipes, choosing stainless steel pipes is the best optionZBeneficial to health. The soaking water test shows that all indicators meet the relevant national standards for drinking water. The inner wall of stainless steel pipes is smooth. After long-term use, they will not accumulate scale and are not easily contaminated by bacteria. There is no need to worry about the water quality being affected, and it can also prevent secondary water pollution.

　　All raw materials are of grade304,304L,316,316LAll complyJIS4305Requirements. The above grades feature stable performance, high strength and low coefficient of thermal expansion.

　　The thin and dense chromium-rich oxide film on the surface of stainless steel makes stainless steel water pipes have excellent corrosion resistance in all water qualities, including soft water. Even when used underground, they still have excellent corrosion resistance. Field corrosion test data show that the service life of stainless steel water pipes can reach100It requires almost no maintenance throughout its service life, avoiding the cost and trouble of pipe replacement, and has a low overall usage cost.

　　Stainless steel can be-270℃－400℃It can work safely for a long time at a certain temperature. Whether it is high or low temperature, no harmful substances will be released and the material properties are quite stable. The tensile strength of stainless steel water pipes is greater than530N/mmAnd it has good ductility and toughness. I love stainless steel news. The high strength of stainless steel pipes greatly reduces the possibility of leakage due to external forces, significantly lowers the water seepage rate, and effectively protects and utilizes water resources.

　　The inner wall of stainless steel pipes is smooth, with very low water resistance, reducing pressure loss and lowering the transportation cost

　　Cost. Due to the low coefficient of thermal expansion of stainless steel, it effectively reduces heat energy loss in hot water pipes. Stainless steel material is100%Renewable materials will not cause public harm to the environment.

　　Stainless steel pipes can be widely used in cold water, hot water, drinking purified water, air, gas, medical gas, petroleum, chemical, water treatment and other pipeline systems.

　　Since human beings began20Since the invention of stainless steel in the century, it has now become a common material. At present, among the performance-to-price ratios of water pipes made of various materials,ZThe best option is stainless steel water pipes. This is related to the superior properties of stainless steel materials, such as corrosion resistance, high strength and strong impact resistance. Its service life can be said to be the same as that of the building. Once you invest, you will benefit for a lifetime. It can be said to be "once and for all".

　　1Extrusion connection---------The pipe fitting is clamped onto the pipe by radial contraction external force (hydraulic clamp) and passed throughOThe water stop of the type sealing ring achieves the connection effect. The connection strength is low (the connection strength of the interface is less than that of the pipe body)1/3The pipeline is not detachable. If the burrs and flash at the pipe ends are not removed thoroughly, it will damage the rubber ring and become a hidden danger of leakage in the future.

　　2Expansion ring connection---------The pipe fitting is clamped onto the pipe by radial contraction external force (hydraulic clamp), and the connection effect is achieved through the water stop of the wide rubber sealing ring. It is detachable. The installation of the pipe adds the process of rolling the convex ring at the pipe end. The cost of cast pipe fittings is relatively high, but the interface strength is better than that of the compression type.

　　3Welded connection---------The two connecting parts are fused by using the hot-melt process to achieve the connection effect. The connection strength is high, but the gas protection of the weld seam at the on-site welding joint is difficult to meet the standard, resulting in the weld seam being prone to rust and directly reducing the service life of the pipeline. The installation quality is highly dependent on the skills of welders and the quality is difficult to stabilize

　　4New connection methods----------The typical plug-in self-locking spring type connection is currently availableZOne of the simple construction methods. The operation is simple and convenient. Construction workers only need to be familiar with its operation requirements and can master it after a little practice. When connecting, the end face of the pipe cut should be perpendicular to the pipe's axis. Burrs on both the inside and outside of the cut should be cleaned thoroughly. Use a marker pen to mark the depth to be inserted on the outer side of the pipe's front end. Then, forcefully insert the pipe into the pipe fitting until it reaches the end of the pipe.

　　(1It is easy to install, without the need to process threads or rely on the wall thickness of the pipe for connection, and avoids difficulties

　　(2It has many advantages such as labor saving, time saving, material saving, tool saving, site saving, environmental protection and sustainable utilization

　　(3It has low installation risk, is suitable for various installation environments, can be reused, and is environmentally friendly and energy-saving.

　　(4It does not leak, is shockproof, resistant to thermal expansion and contraction, safe to use, durable and reliable

　　(5By process classification - gas shielded welded pipes, arc welded pipes, resistance welded pipes (high frequency, low frequency).
