The company has been committed to the R & D and manufacturing of pressure measuring tubes for many years. The pressure measuring tubes produced are deeply loved by the majority of merchants. Piezometric tube is an ancient and common seepage monitoring instrument. It indicates the seepage pressure by the height of water column in the tube. In the observation of hydraulic structures, piezometric tubes are often used to monitor the groundwater level, dam phreatic line, pore water pressure, seepage around the gate dam, seepage pressure at the dam foundation, uplift pressure of concrete gate dam, external water pressure of tunnel and culvert, etc.Precautions for the use of pressure measuring pipe:(1) During seepage pressure monitoring, the purpose shall be clear and the observation section shall be formed. The measuring points shall be specific to the specific measuring points and specific physical quantities of the dam body, dam foundation, around the dam or fault. The layout of the measuring points shall be determined according to the specifications, experience and specific projects.(2) The construction requirements are very high, and the construction quality must be ensured. Sensitivity test and elevation review of inlet pipe and nozzle must be carried out regularly during use.(3) Due to the increasingly important role of temperature monitoring data in seepage analysis, attention must be paid to instrument selection and measurement methods.

Ningjin youlilai ultra high pressure hose detailed introduction, ultra high pressure hose main manufacturer introduction!Main uses of ultra-high pressure hose: it is mainly used for liquid transmission of high-pressure conveyor in automobile industry, engineering machinery and hoisting and transportation machinery, and can be used as special pipe for high-pressure painting. Ultra high pressure hose is an essential part of daily life and can be used in many places. High pressure hose is divided into: fiber reinforced polyurethane hose, fiber reinforced nylon hose, steel wire reinforced polyurethane hose, steel wire reinforced nylon hose, steel wire entangled resin hose and food grade hose. Heat resistance and aging resistance, high pressure and excellent pulse function.Function: good oil resistance.Ultra high pressure hose product features: smooth appearance, small bending radius, the minimum bursting pressure of various hoses is 3 times of the working pressure, high pressure hose has good oil resistance, heat resistance and aging resistance, high pressure bearing and excellent pulse function.

Ningjin youlilai rubber and plastic products Co., Ltd. solution in the application of high-pressure resin pipe, direct sales of high-pressure resin pipe!Theoretically, the rubber layer in the high-pressure resin pipe is absolutely oil resistant, and there is basically no erosion of the rubber layer by oil. Therefore, after precise crimping, the hose should not have oil leakage or head off. In addition, the bending radius of ultra-high pressure resin pipe is generally larger than that of traditional high pressure rubber pipe in the past, which also affects the design and construction. Since the 1990s, a new type of high-pressure hose product - a high-pressure synthetic resin pipe has surfaced. This problem has been solved after the application of endoscopic measurement technology adopted by many manufacturers. This problem is firstly caused by the insufficient accuracy of the current hose crimping equipment, and secondly caused by the non-standard quality of the pipe joint. However, the new problems constantly exposed in the application of ultra-high pressure resin pipe are indeed worthy of research by production units. The product has been widely used in the United States, Japan and other developed countries; At home, the Resinification of high-pressure rubber hose has also become the guiding force for the upgrading of industrial products.Secondly, the high-pressure rubber hose has soft tube body, small bending radius, and good adhesion between the reinforcing layer and rubber in the tube body; However, the adhesive layer and reinforcing layer in the new ultra-high pressure resin pipe are basically non stick, even if the manufacturer uses materials such as adhesive as compensation; But this is a defect.Third, due to the high hardness of the material used in the rubber layer in the high-pressure resin pipe, many application manufacturers cause a lot of incompatibility when crimping the hose joint, and a large number of products leak oil.
