Installation method of wear-resistant pipe assembly

 When the pressure reaches a certain level, the connection method of the plastic hose will increase the safety requirements. In the case of high working pressure, the method of looper flange is generally used. The commonly used looper flange methods are divided into two types, one is a general high-pressure flange, and the other is a high-pressure self-tightening flange. For scenes with high safety requirements, high-pressure self-tightening flanges are generally used. Flanges are generally standard parts, and there are also non-standard parts. The flange plate and the flange root must be used with supporting facilities, and the method of electric welding is generally used for connection.  Litong has 17 utility model patents, 10 provincial and ministerial scientific research achievements, more than 80 R&D personnel, 55 university teachers, technical doctoral students, postgraduates and senior professional technical personnel. Litong Qingdao Research Office. Litong has 16 prefecture-level scientific research projects and 14 patented inventions, and has a CNAS verification laboratory certified by my country. And built Henan Province High Pressure Hose Technology Research Institute. Litong has a CNAS verification laboratory in Henan High-Pressure High-Pressure Hose Technology Research Institute. LT1306 UPE High Wear-Resistant Concrete Transport Plastic Hose Wear-resistant plastic hose is suitable for transporting concrete, wall mud, cement mortar, gravel and plaster of paris. These types of plastic hoses are able to handle abrasion resistant materials and are designed for sandblasting or plastering machines. Our wear-resistant plastic hoses are soft-walled plastic hoses, which are generally used to transport highly corrosive substances, such as quartz sand, cast steel shot, corundum, and laminated glass. Some abrasion-resistant industrially produced plastic hoses can be used with vibrators to assist foundation settlement of concrete layers during construction. Some wear-resistant plastic hoses can even replace cast-iron drain pipes for transporting aggressive materials or corrosive compounds where installation requires minimal bending or where long-lasting high-pressure hoses are required to have the inherent flexibility.  From October 11th to 12th, 2019, it was held in (branch) Zhengzhou (venue), and was sponsored by the plastic hose belt unit of China Rubber Industry Association, which was sponsored by; Luohe Economic Development and Economic Development Zone Management Committee The host is the 9th Fourth VIP Member Congress of the Rubber Hose Department of the China Rubber Industry Association and the 2019 Rubber Hose Belt Information Technology Community Forum jointly organized by the China Association for Science and Technology and Xinxiang Litong Hydraulic Press Technology Co., Ltd. At the exchange meeting of Luohe hydraulic press vulcanized rubber industry production institutions, Litong was once again selected as the "Top Ten Plastic Hose Enterprises in China".

 Concrete transport plastic hoses are generally used to transport highly abrasive substances such as quartz sand, steel casting shot, corundum, laminated glass. And the plastic hose can be used with vibrators to assist in the treatment of concrete layers during construction. The body layer of the tube is mostly made of UPE and SBR & NR styrene-butadiene rubber. This kind of vulcanized rubber has strong wear resistance. In order to avoid the explosion of the tube body due to the burden of washing, 2~4 layers of stainless steel wire steel are used in the middle. Cord development and improvement Industrial Pipe R&D Center In order to better deal with the difficulty that the raw materials of the pipeline and the transported substances do not have chemical reactions, and to ensure the purity of the substances, it means that the equipment cannot be mixed with other chemical substances (vegetable grease, corrosive chemicals) etc.) to produce a reaction, Litong has tried various materials, and finally made a high-pressure composite hose with inner cavity ptfe raw materials, which can be bonded with the reinforcement layer to increase the working pressure. This equipment can transport high-concentration Strong corrosion of raw materials such as sulfuric acid and hydrochloric acid.
