Why sandblasting pipes usually choose rubber pipes, because rubber is highly wear-resistant, more than 10 times more wear-resistant than general polyvinyl chloride vacuum cleaner wire telescopic hoses, especially suitable for dust, powder, fiber, debris and particle transportation, The high flow rate is very abrasive to the gravel, and the friction of the gravel will not damage the hose, so in general material transportation and sandblasting and rust removal, wear-resistant rubber pipes are generally used. Drinking water pipes are suitable for transporting food and liquids. Drinking water hoses can be used in a variety of applications, such as RV parks or campsites. Due to their non-toxic inner layer, they can also be used to deliver water to edible and fragile plants. To guarantee food grade requirements, the hose The inner layer is made of white NR rubber that meets FDA and 3A requirements, and the outer layer is made of blue, which is different from other colors. The strength of the piping system maximizes the dynamic response of the MPD drilling fluid return hose. The MPD system generally diverts the return oil to the control manifold on board through two 6-inch ooze return hoses. Depending on the type of MPD system, a third hose is sometimes used to relieve pressure or supply fluid to control equipment.
