French bolts are evenly tightened evenly, and they must not be excessive. After the bolts are tightened, the two flanges should be parallel to concentric. The threads exposed outside the nut should be 2 ~ 3 buckles, at least not less than 2 bundles, and make each bolt of each bolt. The exposure length is basically the same. During the installation process, it is not allowed to use strong pull, strong push, strong twist or modification of the thickness of the sealing pads to make up for the manufacturing or installation error. If the pipeline installation work cannot be continuously carried out and completed, the open mouth should be closed in time. The parts of the instrument sample on the pipeline should be installed at the same time as the pipeline.
Litong Hydraulic uses stable product quality to high -end products. The company has won the honorary title of "Top Ten Chinese Pipe Tube Enterprises" issued by the Gas Pipe Tape Branch of the China Rubber Industry Association for eight consecutive years. Outputting to our company, technology is productivity. The company uses scientific research talents as a strategic reserve, implements strategies for the introduction of talents, and adds new blood to the R & D team. On August 12, 2019, the Lihe Litong Hydraulic successfully obtained the ABS certification issued by the American Class Society, mainly related to the 7K, 16C, 16D certificate related to the oil drilling hose. Lauride Class Club is one of the earliest aircraft -grade clubs in the world. It has the most stringent revision standards. It is well known in the world's naval field. Its strict testing and control of certified products have been highly recognized internationally. The National Petroleum Diamond Midbar Bidding Commission prepared by the Management Committee is mainly engaged in the standardization of drilling, production, mining equipment and tools in the oil and gas industry.
At the same time, he also serves as the ISO/TC67 Commission of the International Standardized Organization and the Domestic Hand of the United States Petroleum Society (API). In addition, our company has successfully obtained certification certificates such as the API7K16D of the association, indicating that the high -pressure wear -resistant hose produced by our company has corresponding international standards. Luohe Litong Hydraulic Technology Co., Ltd. has undergone 17 years of historical journey in the field of rubber hose production, research and development, and sales. In terms of architecture mining, many machinery faces great challenges. The Super Artiss super strong god series hose recently launched by Litong hydraulic pressure can resist the challenges of high pulse, high pressure, sunlight sun exposure, mud water washing, etc. High pulse can reach 600,000 times. The LT401L PTFE low -pressure multi -functional industry management is widely used in various fields such as chemical industry, steel buildings, and food and pharmaceutical industries. The strong omnidirectional, this characteristic makes it a high -quality choice for the food and pharmaceutical industry; the maximum temperature resistance of the tube is 220 degrees Celsius, and supports customized 4 \ '\' and the inner diameter of the inside.
