Although API 16d plastic hose is only a spare part used on the blowout preventer, its effect on construction safety can not be ignored. In order to ensure the safety of petrochemical industry, Litong strictly implements the provisions of API Q1 quality certification system, and on this basis, it actively and scientifically studies and improves the characteristics of plastic hose. For example, NBR is selected for the inner layer, while heat-resistant and fireproof styrene butadiene rubber and 316 armored cable are used for maintenance outside. All the design schemes and structures are to serve and guarantee the safety of petrochemical industry. On June 25, 2015, the Qingdao Research Office of Litong hydraulic press fell into Hukou plastic valley. On July 13, 2015, Litong hydraulic press held the oath ceremony of the third enterprise zero defect day. On August 13, 2015, the "first excavator service vehicle" of Litong hydraulic press excavator was officially launched. On October 27, 2015, Litong hydraulic press exhibited 2015 Asia Pacific international driving force transmission system and control system exhibition. If the pipe body or socket of concrete plastic hose is damaged, cracked or too thin, the pipe carding cannot be used. For the placement of the pipe body of the wear-resistant pipe, the first consideration is whether all underwater concrete can work normally, and the second consideration is to reduce the length of transportation and bending as much as possible, so as to achieve the goal of reducing the transportation distance. The extension of the transportation distance of wear-resistant plastic hose will increase the normal working pressure of the pipe body during its work. When it is under the abnormal pressure of high load for a long time, the service life of the pipe body will be greatly reduced and certain unsafe factors will be produced. With solid product quality, Litong has been recognized as a specific manufacturer of military weapons and equipment. The company's equipment cooperates with military equipment manufacturing companies to achieve the application of military industry under harsh standards and conditions, and the stability and reliability of high-grade military machinery and equipment under unique natural environment and unique weapons and equipment. Fully meet the application requirements of equipment manufacturing industry, crude oil exploration, steel metallurgy industry, urban rail transit, electric energy, chemical plant, etc. Litong high-pressure and large-diameter industrial pipe production line announced in 2019 that the production and manufacturing of high-pressure and large-diameter rubber pipes can reach 12 inches. This facility is manufactured by importing German VP large-diameter winding and packaging machine. This type of rubber hose is mainly used in special industries, such as mining and coal industry. Its product characteristics are leading in China. Litong continues to release new products and release fire-resistant, heat-resistant and weather resistant parts in rubber and plastic products, It is widely used. The rubber hose of high-quality heat blower is soft and light plastic hose. Its price has good advantages and can be used competitively. In this use, the most important operating characteristics are not the key problem. The plastic hose is suitable for transferring the non oil soluble warm air up to 163 ° C (325 ° f) from the air inlet branch fan on the dry test transport truck or the refrigeration compressor in the processing plant to the storage tank for dry bulk raw material transportation. This kind of warm air is dedicated to removing moisture accumulation in dry bulk goods.
