Mechanical property PFA Bellow Hoses PFA Corrugated Tube corrugated pfa tubing
Corrugated tube refers to a tubular elastic sensitive element connected by foldable wrinkled sheets in the direction of folding and expansion. Bellows are widely used in instruments and meters, mainly as measuring elements for pressure measuring instruments, converting pressure into displacement or force. The corrugated pipe has a thin wall and high sensitivity, with a measurement range of tens of pascals to tens of megapascals. Corrugated pipes mainly include metal corrugated pipes, corrugated expansion joints, corrugated heat exchange pipes, diaphragm boxes, and metal hoses. Metal corrugated pipes are mainly used to compensate for thermal deformation, shock absorption, and absorb settlement deformation of pipelines. They are widely used in industries such as petrochemical, instrumentation, aerospace, chemical, power, cement, and metallurgy. Corrugated pipes made of plastic and other materials play an irreplaceable role in media transportation, power threading, machine tools, household appliances, and other fields.
