Dredge ball joint

A dredge ball joint is a connection between two pipes that are used to transport a mixture of water and sand from a dredger to the discharging area.

Dredge ball joint design

The inner diameter of dredge ball joint pipes ranges from 400 mm to 1200 mm. Dredge ball joint liners can be produced from steel and hard iron materials. To allow for variations of the tilting angle, the ball turning angle of a dredge ball joint is 15 degrees to 18 degrees, and the discharge pipe variation for a dredge ball joint ranges from 10 mm to 30 mm. The dredge ball joints are made to operate at low, medium and high pressure.

Dredge ball joint materials

Dredge ball joints can be made from Cast iron of a manganese, chromium, nickel and molybdenum alloy, ductile manganese iron, or hard chromium iron.

gollark: Why would they not:- look at stuff from orbit beforehand, or send unmanned probes- have at least basic weaponry available for defense against possibly hostile native life- have waaaay better medical technology and/or environmental protection stuff, thus making the deinosuchi not very threatening
gollark: Oh, and they need good shielding against high-velocity particles, which might work okay against some weapons fire.
gollark: Any drive capable of bringing you up to ridiculous fractions of lightspeed will have a horribly dangerous exhaust, the power sources necessary could also run tons of weapons, and you can use said drive things to, I don't know, accelerate asteroids to high velocities and crash them into planets.
gollark: Ah, but their ships themselves would have to be weapons to travel interstellarly.
gollark: Technologically speaking.
