Tips for using corrugated pipes mainly include the following aspects:
Installation tips:
Accurate measurement and positioning: Before installing the pipe body, the axis of the culvert and the position of the inlet and outlet must be accurately determined. During the assembly process, it is necessary to pay attention to the corresponding position of the end plate and the middle plate.
Ensure uniform force: The pipe body should fit tightly on the gravel layer to ensure uniform force. The slope of the top surface of the base layer must be consistent with the design slope, and a pre-arch is set in the transverse direction of the pipe body, with a value of 0.2%~1% of the length of the pipe section to prevent the middle of the pipe from sinking or forming a reverse slope.
Symmetrical installation: The pipe body is formed as a whole by connecting several pieces of Q235 hot-rolled steel plates, and then connected longitudinally to ensure symmetrical installation from the center to both ends. During installation, the bottom plate should be installed first, and then spliced upward layer by layer. For every 5-meter pipe section installed, the roundness and position correction should be performed once.
Precautions during use:
Avoid exceeding the upper limit of the load: When using a bellows weighing sensor, pay attention to the load used to avoid exceeding the upper limit of the load. At the same time, read the instructions and pay attention to anti-corrosion work to keep the sensor surface clean.
Anti-corrosion and cleaning: During the use of the bellows, attention should be paid to anti-corrosion work, keep the surface clean, and avoid corrosion affecting its performance and service life.
Definition and function of bellows:
Definition: Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the folding and stretching direction. The bellows has multiple transverse corrugations and can produce displacement under the action of pressure, axial force, transverse force or bending moment.
Function: Bellows are widely used in instruments and meters. Their main purpose is to be used as a measuring element of a pressure measuring instrument to convert pressure into displacement or force. It can also be used as an isolation element, compensation element, etc., suitable for various complex environments and working conditions.
