There is also a security issue. The use of the sandblasting machine itself is usually used to complete the sandblasting process, so many large enterprises have their own sandblasting rooms. If it is dangerous to use the sandblasting room, what should we do? When the accident occurred, because the sandblasting machine adopts high-pressure wear-resistant pipe, the pipe wall rupture is very dangerous, and the operator is out of danger as soon as possible, and the ventilation equipment provides fresh air to the operator through the protective clothing and helmet. Efforts are made to develop various types of hoses with higher performance. Litong has now established a special military-grade product division, and the company provides professional after-sales and logistics service personnel for each customer. Litong Hydraulics also has advantages in the product vulcanization process. Our production technology has reached the international advanced processing technology standards. High-end production equipment, production capacity, technical level and equipment power are in a leading position in the industry. A long-term production of engineering equipment in Shaanxi, sandblasting machine, shotcrete machine and its accessories, involving sandblasting, material spraying and other equipment. The shotcrete pipes produced by the company can reach 100,000 square meters of sandblasted concrete, and the company supplies wear-resistant materials for sandblasting pipes. The company has reached a long-term cooperative relationship with the company. The company provides 10,000 meters of sandblasting pipes for sandblasting machines, shotcrete machines, mixing stations and other equipment every year. The products have excellent wear resistance and are satisfied by customers. On January 9, 2020, the second phase of the lean project was successfully organized.

The rapid growth of oil demand has brought huge market demand for oil diamond high-pressure wear-resistant hose. The oil diamond produced by our company adopts API 7K and API 16D provided by the special high-pressure wear-resistant hose (API) of the American Petroleum Institute. It is a reliable choice for oil drilling and production work. Through the continuous efforts of Litong people, the high-quality rubber materials imported from Germany produced by Litong have been introduced to the rubber product market. The GK190E automatic production line with an annual output of 10,000 tons of rubber compound can also be put into operation without any problems. At present, Litong Xifa compound rubber manufacturer has the integration of Qingdao soft control automatic dosing system GK190E automatic compound rubber which represents domestic technology. Production Lines and MES The system creates extremely precise automated and computerized production methods.
