The weight of 600 bellows is: the weight of a 6m DN300 HDPE bellows is 60 or 70 catties (wave distance + 2 waves such as rolling height) * number of corrugations * diameter circumference of straight side section * wall thickness.
Bellows refers to a tubular elastic sensitive element connected by foldable wrinkle sheets along the folded and telescopic direction.
Bellows are widely used in instrumentation, and their main purpose is to act as a measuring element of pressure measuring instruments to convert pressure into displacement or force.
The bellows have a thinner wall and a higher sensitivity, with a measurement range of tens of Pa to tens of megapascals. It is fixed at the open end, free at the sealed end, and utilizes auxiliary coil springs or reeds for added elasticity.
During work, it elongates along the length of the pipe under the action of internal pressure, so that the displacement of the active end has a certain relationship with the pressure failure. The movable end can be driven by the pointer to directly point to the rubber to detect the amount of pressure. Bellows are often used with displacement sensors.
Combined, they form a pressure sensor with an output of electricity.
It is also sometimes used as an isolation element. Since the extension of the bellows requires a large volume change, it responds at a slower speed than the Bourdon tube. Bellows are suitable for measuring low pressures.

Hello dear! We'll be happy to answer for you. 70 bellows per meter multiple answers:
The diameter of one meter bellows is about kilograms per meter. In fact, the quality of different metal bellows specifications, different inner diameter sizes, and different metal bellows wall thickness is also different. For example, the inner diameter of the wall thickness of millimeters is guess that the weight of the metal bellows of the 50 mm brother stove is about kilograms per meter, and the weight of the metal bellows with an inner diameter of 60 mm is kilograms per meter.
The wall thickness is mm, and the weight of the metal bellows with an inner diameter of 50 mm is about kilograms per meter, so the weight of different planning models is also different.

Hello dear! We'll be happy to answer for you. HDPE bellows 1 meter diameter 200 more than A:
Hello, the weight of a 6m DN300 HDPE double-wall corrugated pipe is about 120 kilograms, the outer diameter of HDPE double-wall corrugated pipe DN300 refers to the nominal diameter, and DE refers to the outer diameter of the pipe 1, DN represents the nominal diameter; de stands for the outer diameter of the pipe; SN8 and 8KN M2 refers to the nominal pressure of the pipe, SN8 and 8KN M2 represent the ring stiffness of HDPE double wall corrugated pipe, the pressure per square meter can withstand greater than or so thank you for your patience and wait for cavity leakage. The above is all my reply, if my service is full of lead, please give a thumbs up, and then I wish you all the best! Peace and joy!
