About the working pressure of the steam hose
The oil pipes of Litong brand are divided into the right types. Most people only know crude oil transportation, but few people know the oil return hose. half, suitable for petroleum-based hydraulic oil, water and glycol, flame retardant water-based hydraulic oil, lubricating oil, crude oil, fuel oil and water. Therefore, it has a very wide range of applications and has characteristics such as high temperature resistance. Introduction to the basic functional characteristics of the steam hose: 1. The working pressure of the steam hose is generally not more than 30 kg, but the burst pressure is generally 10 times the working pressure; 2. The middle reinforcement layer of the steam hose is mostly braided with steel wire or polyester wire. As a manufacturer, we It is recommended to use less cloth, the service life of the cloth is too short, and it is easy to bulge; 3. The service life of the steam hose is generally more than one year. In the petrochemical hose wear-resistant hose, if there is a problem with safety and working pressure Certain requirements, generally used for B type (A, B, C, D pressure from low to high) wear-resistant pipe: its working pressure is about 5MPa ~ 7MPa,…
How to extend the service life of hydraulic pipes
Litong has been trying various methods to bond rubber, synthetic rubber, especially non-polar synthetic rubber. The self-adhesion of this rubber is too poor, which makes it difficult for the rubber layers to stick together, which requires immediate and appropriate modification. For example, the introduction of resin into the molecular chain can also creatively add polar resin to rubber to improve its performance. The use of the hose must ensure good adhesion, so when using glue and printing, an intermediate transition adhesive layer can be used. The special process adopted by Litong improves the bonding performance. Hydraulic pipes are relatively fragile parts of the excavation. A basic set of hydraulic tubing is expensive. The most important thing is to prolong the life of the hydraulic pipes. The main thing is that the driver should be gentle when working, not high power and high risk. Sex cycle, in addition to the correct maintenance method, also greatly affects the service life of the hydraulic pipe. Be sure to use protection rings, two do not rub, three do not touch diesel, four lubricating interfaces, and five are installed in place. Customers can maintain their equipment as long as they comply with this standard. Heat-resistant hose…

How Industrial Hose Pumps Work
As far as the working principle of the industrial hose pump is concerned, a special rubber hose is generally installed inside the pump, and is rotated and squeezed along the hose through a pair of pressure rollers, so that the medium is transported in one direction without backflow. After the hose conveys the medium, the hose is restored to its original state by the elasticity of the flattened hose and the side guide roller. At this time, a high vacuum is generated in the hose to suck the medium into the lumen again, and then the medium will follow. The pressure roller is squeezed and discharged from the hose. In this way, the medium is continuously sucked in and discharged. The oil drilling hose is mainly used in the oil drilling and production industry. It is a special rubber hose with high strength, high toughness but good flexibility. The maximum operating pressure of the oil drilling hose can reach 70 MPa, so in some places, the high-pressure oil drilling hose is also called a high-pressure hose. The oil drilling hose should be connected by heavy hammer or high pressure joint during installation to ensure its safe and reliable performance. On…
EPDM rubber is widely used
Why are anti-wear hoses widely used in the world? Due to its strong corrosion resistance, in many factories, the chemical products used are extremely corrosive and easy to damage the hose, while the wear-resistant hose has very strong corrosion resistance and can effectively complete the transportation. Tube, this feature is not available. Therefore, from a practical point of view, when it is necessary to transport corrosive chemicals, it is more reliable to choose wear-resistant hoses. This problem has also attracted the attention of many manufacturers. LT1217 300PSI hot tar asphalt dressing delivery pipe is mainly used in the delivery of hot tar and asphalt. The inner part of the pipe is made of black nitrile rubber, the middle is reinforced with high tension steel wire braid, and the outer part is made of black chlorine Butadiene rubber (CR) can withstand up to 180 degrees Celsius and can work continuously under a constant pressure of 300 psi. The size of the pipe body can generally reach 8 inches, which can be customized. EPDM has a wide range of uses, such as tire rubber strips and inner tubes, as well as auto parts, as well as wire and cable sheathing and high-voltage…

UPE sandblasting hose maintenance tips
Regarding the service life of sandblasting hose, it is recommended to use Letone customized UPE sandblasting hose for continuous operation environment. Of course, before the sandblasting operation, checking the wear of the joint is also a maintenance technique to improve the service life of the pipe body. In addition, different brands of sandblasting equipment and sandblasting hoses have different types of joints. You can confirm with your account manager before choosing to buy, or customize special joints. The selection of oil extraction hoses should select different hose assemblies according to the different media to be transported and different working pressure levels to prevent different media from eroding the pipe body and media leakage, resulting in undue losses and vicious accidents. Accidents caused by improper selection of oil hoses occur from time to time. Generally, substitutes cannot be used, and they need to be specially managed and used properly to avoid accidents. Over the past 17 years, Litong Hydraulics has insisted on taking continuous innovation and development as an opportunity to promote product technology innovation, accelerate the pace of new product development, and actively attract outstanding talents.
