Four layer steel wire wound high-pressure hydraulic oil pipe is mainly suitable for petroleum based hydraulic oil and working environment under harsh conditions. In order to ensure that there are four steel wire winding layers in the middle of the high-pressure resistant pipe to ensure that the pipe can withstand the maximum pressure, the pipe body meets the requirements of SAE 100R12 standard and GB / t10544-2013 standard. In addition, the hose series has excellent hydraulic oil compatibility and high-performance functions, which can be perfectly presented in design, manufacturing and finished product testing. By virtue of excellent product quality, Litong has obtained military quality, designated military equipment production units, company products and cooperation with military equipment manufacturing enterprises to meet the application of military enterprises under harsh conditions and harsh environments, and the reliability and stability of high-end military equipment under special environments and special equipment. Flexible use of various equipment manufacturing, oil drilling can adapt to various environments, and our pipeline is also the first choice in the iron and steel metallurgy industry. LT301API 7K series &mdash&mdash rotary drilling and damping hose: mainly used for flexible connection between vertical pipe and rotary pipe (rotary drilling) or pump and vertical pipe (rotary vibrator), for high-pressure pumping oil drilling exploration slurry, water emulsion cement slurry, mineral oil, ethylene glycol, polyethylene glycol inner diameter NR&SBR/HNBR/UPE material has good chemical stability and wear resistance. The reinforcement layer 2-6 layers of steel wire spiral is adopted, the external synthetic rubber is weather resistant, and the overall pipe fittings meet the international requirements API 7K standard. On April 11, 2016, Litong Hydraulic Co., Ltd. participated in the 2016 BMW exhibition in Germany. The company's newly developed products and special exhibition exhibits have been transported to the exhibition. On December 12, 2016, Litong hydraulic amoeba project was fully launched. On September 19, 2017, the company won the "top ten rubber hose enterprises in China" again for six consecutive years, In 2016, Litong successfully launched super artery And successfully launched a series of PTFE high, medium and low pressure series multifunctional hose products, which are widely used. What are the advantages of PTFE hose? 1 excellent atmospheric aging resistance, radiation resistance and low permeability. It can be exposed to the atmosphere for a long time, and its appearance and function remain unchanged. 2 Excellent high and low temperature resistance. PTFE hose has little effect on temperature, wide temperature range, large melting point of 327 ℃ ~ 342 ℃, and can work for a long time at 250 ℃ ~ 180 ℃ Excellent corrosion resistance. It can remove molten alkali metals, fluorinated media, strong oxidants, reducing agents and various organic solvents. 7K standard hose, commonly known as drilling hose, common accessories include buckle sleeve (iron sheet), buckle connection (steel core) and hammer of specified size. The joint type is generally confirmed at the beginning of the order and designed or purchased by the company's special department. After the pipeline test, it is operated by the assembly buckle department and buckle operation. Each hose will be subject to special pressure test and joint test to ensure that the product will not have quality problems during use.
