API 16C Series – Choke and Kill Hose: Flexible Connections in Valve Blocks and Kill Manifolds for Onshore and Offshore Blocking, Kill Line Drilling and Repair, this body is designed to API 16C , is composed of inner core, 4~6 layers of high-strength steel wire winding reinforcement layer, heat insulation layer, fireproof layer, buffer and sealing layer and stainless steel sheath, the pipe body can meet the needs of drilling equipment, and the pipe body has certain flexibility and easy operation. In March 2018, the bonding of PTFE rubber was successfully achieved. The breakthrough of this process not only solved the core-off defect of PTFE pipe body in application, but also opened up more application fields, making Teflon hose widely used in chemical, pharmaceutical, etc. , food, chemical industry and many other fields have been perfectly applied, which not only reflects Letone Hydraulic’s superb technology in rubber hose technology, but also achieves a milestone breakthrough in rubber research and development, becoming the first manufacturer in the world to realize the bonding of PTFE materials. Braided steel wire hoses can be used to transport chemical gases and solvents at high temperature and pressure. 

In addition, the tube body can provide a flexible connection between the steel tubes in the retention system. It is widely used in mine hydraulic support, automatic hydraulic system of oil field excavator, mining engineering and other industrial fields, especially as a component of jackhammer. The pipe body can continue to work in the environment of -40℃~+100℃, and the maximum temperature is +125℃. The surface of steel wire braided hydraulic hose can be divided into two types: smooth surface and fabric surface. The ultra-high pressure hose has the following characteristics: (1) High pressure bearing capacity; (2) The inner and outer walls of the ultra-high pressure hose are smooth, the fluid resistance is small, the hydraulic loss is small, and the operation efficiency is high; (3) The adaptable temperature range is wide: ultra-high pressure The hose can adapt to the minimum temperature of -70 ℃ and the maximum can adapt to 300 ℃; (4) the ultra-high pressure hose also has the characteristics of light weight, small volume and good flexibility.Although the domestic research on flexible pipes started relatively late, it has developed rapidly in the fields of design and manufacturing, and the manufacturers have already possessed the technical strength of engineering applications on the basis of years of research and development and trial production.

Among them, Letone Hydraulic Co., Ltd. has developed a wear-resistant acid fracturing hose for oil drilling and production, which is used for acid fracturing, sand fracturing, water fracturing, water fracturing, water-based, foam, acid-based fracturing in well completion operations. equal fracturing fluid. Letone Hydraulics has obtained a variety of technical certificates to ensure that it can meet the needs of customers. Letone has passed product certifications, including safety standards (MA), MSHA, American Petroleum Institute (API) API-16C and API-7K, American Bureau of Transportation ABS (oil drilling equipment and steel wire), labor fire certification, etc. It fully meets the needs of equipment production, oil drilling, iron and steel metallurgy, railway transportation, energy, chemistry and other fields.
