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.
On August 12, 2019, Luohe Litong Hydraulics successfully obtained the ABS certificate issued by the American Bureau of Shipping, mainly 7K, 16C, 16D certificates related to oil drilling hoses. Lloyd's Register is one of the earliest established classification societies in the world, with the most stringent revision standards, well known in the world's naval field, and its rigorous testing and control of certified products are highly recognized internationally, steam hoses, Namely the steam hose. It is used for cooling water of refrigeration equipment, hot and cold water of engine, food processing, especially hot water and saturated steam of dairy products factory. It is resistant to dilute (low concentration) acid and alkali. Structure: The steam hose is the same as the ordinary industrial hose, which is composed of inner rubber, outer rubber and middle layer. Steam hose with braided wire, water bag and wrap. The commonly used internal and external rubber materials are made of EPDM materials with excellent heat resistance, steam resistance, ozone UV resistance and chemical properties, and the outer glue is wrapped with tape.
The middle layer is generally braided wire or braided steel wire to strengthen the pressure bearing range of the hose. In September 2017, Litong signed the largest equipment purchase agreement since the factory was established in 2003. The company plans to launch 100 Meyer knitting machines within 5 years to support the rapid upgrade of the company's products and provide customers with screaming, becoming the first in China and a world leader in the production of flexible hoses. The Mayer braiding machine is one of the most advanced high-speed braiding machines in the industry, it can achieve 3X3 braid layers, less braiding knots and better pulse performance compared to other machines.
