Description

High-strength HDPE double-wall corrugated pipe

Technical Field

The utility model relates to the field of corrugated pipes, in particular to a high-strength HDPE double-wall corrugated pipe.

Background

The corrugated pipe is a tubular elastic sensitive element which is formed by connecting foldable corrugated sheets along the folding and stretching direction. The corrugated pipe has wide application in instruments and meters, and is mainly used as a measuring element of a pressure measuring instrument to convert pressure into displacement or force. The corrugated pipe has thin pipe wall and high sensitivity, and the measurement range is from tens of Pa to tens of MPa. Its open end is fixed, its sealed end is in free state, and its elasticity is increased by using auxiliary helical spring or reed. When working, the pipe is extended along the length direction under the action of internal pressure, so that the movable end generates displacement in a certain relation with the pressure. The movable end drives the pointer to directly indicate the pressure. Bellows are often combined with displacement sensors to form pressure sensors that output an electrical quantity, sometimes also acting as isolation elements. The response speed of the bellows is slower than that of the bourdon tube because of the large volume change required for the expansion of the bellows. The bellows is adapted to measure low pressure.

The HDPE double-wall corrugated pipe is not enough in use at the present stage, a plurality of corrugated pipes are inconvenient to connect, the use strength is not enough, and the use cost is increased, so that the problem is solved by a high-strength HDPE double-wall corrugated pipe.
