Polyethylene Winding Structural Wall Tube
Polyethylene Winding Structural Wall Tube
The kra pipe can be divided into PR, OP, SQ, and VW series, among which: PR and OP are mainly used as buried drainage pipes. SQ is mainly used to make containers or inspection wells. VW is mainly used for pipe fittings formed by tee, elbow, and secondary processing. PR series is the most widely used in the products, which has a smooth inner surface and abnormal external reinforced structure. The standard length of the pipe is 6 meters. The inner diameter range of the pipe is DN300-DN4000, and the product indicators all meet the requirements of GB/T 19472.2-2017 type B structure wall pipe standard and EN-13476 European standard.

The first products of the STCL1120 series are 10MHz, 12MHz and 16MHz oscillators. 12MHz product start-up time of only 50 microseconds, the current work in similar products in the lowest (0.65mA), chip-select feature allows engineers to save energy, this product is low cost, high stability and durability, is an alternative to ceramic or crystal oscillator The best solution. Another great advantage of the STCL1120 is that it eliminates the need for external components and solves the capacitor matching problems that often occur with ceramic resonators. The STCL1120 is also powered directly from a 5V supply.
STCL1120 external chip select pin allows design engineers to easily stop the clock when the application is in standby mode, the oscillator current is reduced to 3 microamperes or less, save more energy. Compatible with CMOS push-pull output pin may generate a square wave signal, so that the oscillator components directly interface a circuit board, including a logic device, a microcontroller, the FPGA (field programmable gate array) and ASIC (application specific integrated circuit).
The accuracy of the fixed operating frequency of the STCL1120 is ±1.5% under all operating conditions. ST also introduced a 32kHz silicon oscillator and will soon introduce a derivative of this product. STCL1120 rated operating temperature range of? 20 ℃ to + 85 ℃, certain applications including motor control, household appliances, building control devices, a display driving circuit, the charger and advanced low-speed USB peripherals (such as a computer keyboard or mouse).
The STCL1120 series is available in a 5-pin SOT23 package and is available in volume quantities.
1. Municipal water supply and drainage: The internal pressure of high-density polyethylene (HDPE) winding reinforced pipe can reach 12kg/cm2, which is the ideal pipe to replace the original drainage cast iron pipe and cement pipe in the city. The pipe can be used for municipal underground drainage, sewage, rainwater collection, water transmission, ventilation, etc to discharge liquid and gaseous substances into rivers or the sea. Thermal structure wall winding pipe has the advantages of lightweight, safe, reliable connection,corrosion resistance, and high ring stiffness, therefore the use of thermal structure winding pipe has great advantages.
2. Large-scale water conservancy projects: long-distance water transmission, farmland irrigation, reservoir drainage, water source pipe, irrigation pipe and hydropower station water transmission, drainage use;
3. Environmental protection engineering: deep sea sewage, sewage treatment, waste
dump sewage, detoxification pipeline. Due to the thermal structure wall winding pipe of various pipe wall structures and pipe, inspection well, pipe fitting, and its reliable connection performance, the pipe can be used for advanced shallow drainage systems.
4. Petroleum industry: oil, gas pipeline.
5. Coal industry: coal transport, ventilation systems.
6. Chemical engineering: chemical containers, especially corrosive fluid delivery
pipelines.
7. Electric power engineering: circulating water pipeline.
8. Road engineering: crossing roads and railways have a large traffic load of water
culverts and crosswalks; Used as railway and highway road seepage, drainage pipe; The method of "liner in pipe" is becoming more and more important for repairing damaged pipes.
9. The laying of pipes in a corrosive environment.
10. Agricultural engineering: farmland, orchard, tea garden and forest belt irrigation, and so on;
11. Large airport port, wharf engineering: large airport port, wharf engineering drainage, sewage pipe, etc.
12. Construction engineering: building stormwater pipes, underground drainage pipes, sewage pipes, ventilation pipes, etc.
Communication tube: railway, highway communications, communication cables, optical cable protection pipe.
14. Water storage system: used to intercept the slow water storage system.
15. Special application: thermal winding wall winding pipe can also be used for special
purposes such as ventilation, passage, desert, swamp, lake area with fluid transport, etc.
