LT301API 7K Series - Rotary Drilling and Vibration Hose: Mainly used for flexible connection between standpipe and rotary pipe (rotary drilling) or between pump and standpipe (rotary vibrator), for pumping at very high pressures Send mud in oil drilling and exploration work, water and mud in water emulsion, mineral oil, ethylene glycol and polyethylene glycol; the inner diameter layer is mostly made of NR&SBR/HNBR/UPE material, which has good chemical stability and wear resistance The reinforcing layer adopts 2-6 layers of steel wire spirals; the synthetic rubber used on the outside is weather-resistant, and the overall pipe fitting requirements meet the international API 7K standard. Litong Hydraulics has always followed the national product safety requirements and has obtained various technical certificates to ensure that it can meet the needs of customers. We have obtained many certifications such as Lloyd's fire certification, various API petroleum certifications, and some professional certifications in the United States, we all have them.
Whether in equipment and oil drilling, or metallurgy and rail, it can meet all the requirements of customers. This is a technology that many domestic counterparts cannot achieve, and this technological advantage is our confidence. There are various types of industrial hoses, which are widely used in petroleum, chemical, energy, construction, steel, machinery, food, medicine and other fields. The Litong PTFE rubber-plastic composite multi-functional hose is undoubtedly the "handle" in the industrial hose. It is not afraid of high temperature, the high temperature of 220 ° C is its daily work, and occasionally it is as high as 260 ° C. Almost all media can be safely transported through it, even corrosive fluid chemicals (sulfuric acid, hydrochloric acid, sulfur reactants, etc.) cannot attack it. Excavator worry-free customer service car, the company draws on foreign high-quality service cases to provide excavator worry-free service car, even if the customer encounters a failure during the construction operation, it will arrive at the site 24 hours, solve problems for customers, check pipeline problems, and be equipped with the car Withholding machines, pipe cutting machines and other maintenance equipment, provide complete joints, tailor-made assemblies, and arrive at the construction site in real time. Really let the excavator worry-free, the construction worry-free, and the project worry-free.
The lining of the hose should be composed of oil-resistant and water-resistant rubber, the reinforcing layer of the pipe fittings is composed of woven cloth and steel wire (rope) materials, and the outer hose is made of oil-resistant, wear-resistant and durable rubber products. In its length direction, there should be a color band on the surface, which is used for pipeline installation, purpose editing, drilling rubber hose, wire winding for oilfield cementing and drilling, maintenance and petroleum geological exploration, small drilling rig and hydraulic coal mining, and conveying liquid medium like mud. The oil hose is mainly composed of inner steel wire, reinforced braided layer, sealing layer, outer reinforcement layer and outer steel wire. Mud and normal temperature water and other fluid media, the oil hose also has good chemical resistance. Frequent bending will not crack and delaminate, suitable for oil, chemical transportation ships, docks, etc.
More about -Chemical Hose- will be updated gradually, so stay tuned.
