Method of delaying the aging rate of PTFE hose

The aging of the PTFE tube is inevitable, we cannot stop it, but we can only try to delay the aging speed of the PTFE tube. In order to help slow down the aging speed of the PTFE tube, it is necessary to strengthen the maintenance when using A series of measures to prevent this. This goal can be achieved through material selection, use and maintenance of piping, and other aspects. Mainly when choosing the PTFE pipe tape compound, it is recommended to use the sulfur vulcanization system as much as possible. The replacement frequency of the hose assembly is greatly reduced, and the service life is greatly improved. This series of hoses has the following remarkable characteristics: The development of the oil and gas industry makes the oil production equipment more and more small in size, light in weight, compact in structure and light in weight, which puts forward higher requirements for equipment manufacturers in the oil and gas industry. The company breaks through foreign technical barriers, masters key core technologies, and has a series of hose industry chains from design, manufacturing, post-maintenance, and maintenance.

 

On January 13, 2020, MBA students gathered early in the company's cafeteria for this week's early education activities. Chairman Zhao Hongliang emphasized the starting point of the company's new year quality improvement project. Teachers and students in the three counties are the backbone of rapid product quality improvement. Learn to use the "PDCA Method of Work" to find, analyze, implement and improve. All discussed seven major improvement projects and formed project teams. High-strength mining hoses are designed for demanding duties in mining and industry for easy suction and discharge applications. The tube body utilizes the toughness and light weight of fibers to reinforce the tube body and is designed to meet high dynamic loads. The inner wall of the pipe is made of black SBR/NBR mixed rubber with oil mist resistance, which can prevent the internal aging of the pipe body. The green SBR rubber used on the outer layer is mainly to protect the pipe body and ensure its service life.

 

There is also a security issue. The use of the sandblasting machine itself now usually uses a sandblasting chamber to complete the sandblasting process, so many large enterprises have their own sandblasting chambers. What if it is dangerous to use a blasting booth? When the accident happened, because the sandblasting machine used high-pressure wear-resistant pipes, it was very dangerous for the pipe wall to break. The operator is reminded to escape as soon as possible, and the ventilation equipment provides the operator with fresh air through the helmet of the protective suit. The tolerance of different media is different. The material of high temperature steam hose is EPDM rubber, EPDM rubber, EPDM EPDM rubber is rubber that has good resistance to water vapor, high temperature steam hose but for oil. , mineral oil, solvent oil is not tolerated, and has a certain resistance to dry hot air, but it is not ideal. Chlorine yellowed polyethylene rubber can be used. It is also possible to use silicone rubber in combination, but it is not easy to bond with the reinforcement layer.
