The difference between hollow board coaming box and other plastic coaming box

Have we learned about hollow board coaming boxes and plastic coaming boxes?Do not understand together to understand the hollow board coaming box and plastic coaming box what is different!Hollow board coaming box is a tubular shell with a closed circular ring.The plastic coaming box is a tubular shell with corrugated and spiral arrangement, which is formed in two adjacent corrugated pipes or by welding.The characteristics of hollow board coaming box and plastic coaming box are different:

1. Hollow board coaming box is a closed circular circular tubular shell with ripples.Its waves are formed by a series of circular ripples.Hollow plate coaming box is made of seamless pipe or welded rolling, and its length is generally short.Half of the metal hose assembled by hollow board coaming box is generally used on shorter pipes or equipment.The advantage of hollow board coaming box is good elasticity, small stiffness and good flexibility.

2. Spiral bellows are tubular shells with spiral arrangement of bellows.There is a spiral Angle between the ripples, and all the ripples can be connected by a spiral.The spiral corrugated pipe is assembled into medium and small size metal hose, the size scale used is 15-400mm in diameter, the wall thickness of commonly used corrugated pipe is 0.15-0.6mm.Spiral metal hose, with thick wall, high pressure capacity, used for the occasion of little movement.

The difference between hollow board coaming box and plastic coaming box

1. The coaming box of hollow board has good soft performance. It is not easy to generate torsional stress when it is stressed and deformed, and it is easy to be matched with various joints.

2, spiral metal hose, with thick wall, high pressure capacity, used for the occasion of little movement.According to the characteristics of two kinds of bellows, choose the right bellows, the ability to play a greater effect!
