Stainless steel valves are parts that connect pipes into pipelines. According to the connection method, it can be divided into four categories: socket fittings, threaded fittings, flange fittings and welded fittings. Mostly made of the same material as the pipe. There are elbows, flanges, tees, crosses (cross heads), and reducers (big and small heads). The elbow is used for the turning of the pipe arm. The flange is used for the parts that connect the pipe and the pipe to each other, and is connected to the pipe end. The tee pipe is used for the place where the three pipes gather. the four-way pipe is used for the place where the four pipes gather. Reducers are used where two pipes of different diameters are connected.
At present, China is already the largest producer and consumer of building materials in the world. The output of major building materials such as cement, flat glass, building sanitary ceramics, stone and wall materials ranks first in the world for many years. At the same time, the quality of building materials is constantly improving, the consumption of energy and raw materials is decreasing year by year, various new building materials are constantly emerging, and building material products are constantly being upgraded.
Under the background of building an energy-saving society and strengthening the country's independent innovation capabilities, the topics of energy conservation and technological innovation will be the hot spots of the industry's development. Stainless steel is a steel material in which several or more than a dozen chemical elements exist at the same time. When several elements coexist in a unity of stainless steel, their influence is much more complicated than when they exist alone, because in this case not only Consider the role of each element itself, and pay attention to their mutual influence, so the structure of stainless steel depends on the sum of the influence of various elements.
When stainless steel is used to make pipes, two types of stainless steel are generally used: 304 and 316. Compared with other pipes, stainless steel has the following advantages:
Good corrosion resistance. Strong and ductile. Easy to form and weld. Not limited by water flow rate, the maximum flow rate can reach 30 m/s. Suitable for various chemical components of drinking water .Little maintenance, low life cycle cost. Multiple connection methods and different types of joints. No need for any water treatment agent except for bacteria control. Non-toxic. 100% recyclable. Consider initial installation costs.
The initial cost of stainless steel is generally higher, but there are many ways to save money:
No corrosion-resistant coating is required. The cost of backup equipment is reduced. Stainless steel parts are lightweight and require less structural support. Lighter weight parts. Lower transportation and installation costs. High flow rates mean smaller diameter pipes can be used. No corrosion allowance required, Allowing thinner pipe walls. Life cycle costs.
Although the initial cost of stainless steel is higher, its life cycle cost is generally lower due to the savings in use costs:
Smooth inner surface can reduce the energy consumed by the pump. Reduce the number of inspections and costs. Reduce maintenance costs and do not need to be recoated . No need to replace. Reduce downtime. Extend service life. 100% recyclable after service life.
In order to ensure the best use effect of stainless steel pipes, it should be ensured that: Horizontal pipes should have an inclination to facilitate drainage. Dead ends should be avoided during design. When using 304, chloride < 200 ppm. When using 316, chloride < 1000 ppm. Use insulation materials with low chloride content (< 0.05% water-soluble chloride ions). If the insulation material will be exposed to wet chlorides, such as: Coastal areas. A protective material should be added between the stainless steel pipe and the insulation material, such as: Aluminum foil. Use of low chloride sealants and anti-galling lubricants. All water must be drained immediately after piping has been hydrostatically tested.
