Although the API 16D hose is only an accessory used on the blowout preventer, its role in engineering safety cannot be ignored. In order to ensure the safety of petroleum engineering, Litong strictly complies with the requirements of API Q1 quality management system, and actively researches and improves the performance of hoses on this basis. For example, NBR is used for the inner layer, and high temperature and fire-resistant synthetic rubber is used for the outer layer and protected by 316 armor. , the entire design structure is to escort the safety of petroleum engineering. Under high temperature conditions, UPE can work continuously at a temperature not higher than 79 degrees Celsius; the chemical tube with PTFE inner layer can work continuously and normally at a high temperature of 210 degrees Celsius. The minimum working pressure is 13.8bar and the maximum is 138bar. No matter how high the pressure is, it is necessary to explain the situation to the customer manager, and it will be customized and developed by the production technology. The length of a single multifunctional chemical delivery pipe is 60 meters. In special cases, when high softness is required, the outer rubber layer generally adopts a tiny corrugated outer wall. For 17 years, Litong has customized products for customers and provided complete solutions. Litong fluid equipment has provided one-stop industry solutions for the company. Professional fluid technology professionals can improve mature fluid technology solutions for customers and create value for customers. Since its establishment, Litong Hydraulics has always put users first, providing customers with perfect after-sales service, and improving customer satisfaction while completing product production. Since 2010, Litong Hydraulics has been rated as an excellent hose enterprise for nine consecutive years, and its comprehensive strength ranks among the top ten in China, which fully shows that Litong Hydraulics has mastered advanced technology in the field of fluid technology, especially in high pressure, high temperature, wear resistance. , In terms of anti-corrosion, Litong has developed new raw material formulas to extend the service life of pipes in these special application fields. The average service life of Litong products is 3-5 times that of products in the same industry. Great cost savings.

   Oil drilling hose structure: composed of inner rubber layer, inner rubber protective layer, middle rubber layer, steel wire winding layer and outer rubber layer. Uses: Steel wire winding drilling hose is used for oilfield cementing, workover and petroleum geological exploration, small drilling rigs and water conservancy coal mining, transporting mud and normal temperature water and other fluid media.
