Usage and maintenance of sanitary mirror: usage (1) cleaning.Before use, you can use an appropriate amount of alcohol cotton to slightly wipe the surface. Note: do not use acidic liquid to clean, so as not to corrode the outer surface of the glass.(2) Select the gasket correctly.Ambient operating temperature within 280 ℃
Stainless steel vacuum negative pressure sterilization filter is widely used in air and gas sterilization filters in biopharmaceutical and biotechnology processes. It is composed of two layers of PALL/PTFE filtration membrane with natural hydrophobicity and chemical inertia, and is specially designed for the efficient removal of contaminated bacteria and viruses.Stainless steel vacuum negative pressure removal
What are grade AP, MP, BA and EP stainless steel pipes?In addition to brand, material and production process, the most important factor affecting the price of stainless steel pipe is the surface treatment method of steel pipe.In order to further improve the characteristics of pipeline materials, there are generally four methods to treat the internal and external surfaces of pipelines: pickling and passivation
1 When designing titanium pressure vessel, its structure must be simple to clean the surface near the weld, and it is convenient to use inert gas to protect the hood, the front and back of the weld and its heat affected zone during welding.2 Industrial pure titanium and titanium alloy can be welded by themselves or between each other, but cannot be fused with other metals.When needed
3D printing additive manufacturing technology is mainly a technology that generates 3D CAD model of parts through computer, and stacks the materials of parts layer by layer in the form of inkjet according to the size data of the model by laser cladding.The additive manufacturing process is simple, the production cost is low, and the application scope is wide,
Stainless steel BA pipe BrightAnnealedtube (vacuum bright annealing pipe), which is the abbreviation of BrightAnnealed, also called: stainless steel BA pipe, clean pipe, bright annealing pipe, seamless pipe, gas pipeline, high-purity gas pipeline, ferrule;Material: 304 precision stainless steel pipe, 316L;Standard: ASTMA24
Leakage causes and prevention methods of anti leakage butterfly valve The leakage of stuffing box of imported butterfly valve is called external leakage, and the closure is called internal leakage.It is difficult to find the leakage of the closing part in the valve.Closure leakage can be divided into two categories: one is sealing surface leakage, the other is seal ring root leakage.The reasons for the leakage of the imported butterfly valve are: 1. The valve rod is bent and twisted, which makes the upper and lower closing parts misaligned;2. The sealing ring is not tightly matched with the valve seat and disc;
Sanitary quick ball valve is a sanitary ball valve used for material transportation.The application range of this valve includes food, beverage processing, pharmaceutical and chemical industries.The sanitary fast ball valve controls the on-off of the medium by rotating the ball.When the ball is aligned with the valve body hole, the medium can pass through smoothly;When the ball rotates to make the orifice leave the valve body, the medium is blocked.Rotation of the sphere is manual or automatic
What should be paid attention to during valve installation?Now let's explain the precautions for valve installation.1. When installing the valve, it is necessary to clean the inner cavity and sealing surface, check whether the connecting bolts are tightened evenly, and check whether the packing is pressed tightly.2. The valve is closed during installation.3. The stop valve shall be installed in such a way that the medium flow direction is consistent with the arrow marked on the valve body. For infrequent opening and closing, it is necessary to strictly ensure that
① Medium composition and concentration.Generally, the corrosion rate increases with the increase of medium concentration, but this is not always the case.For example, carbon steel and stainless steel are corroded most seriously in 50% sulfuric acid, and the corrosion rate decreases sharply when the concentration increases to more than 60%.On the contrary, the lower the concentration of sulfuric acid, the smaller the corrosion rate, but when the concentration exceeds 96%, the corrosion rate increases.Corrosion rate of stainless steel in acetic acid at 80
Three piece butterfly valve is mainly applicable to stainless steel pipeline system in dairy, food, beer, beverage, pharmacy, cosmetics and other industrial fields.What are the main features of the three piece butterfly valve?As shown below: 1. The steel parts are made of stainless steel, and the rubber is made of food rubber, with high sanitary quality.2. The valve bodies are detachable and connected, with simple structure and convenient maintenance.3. The opening and closing range is 0~90 degrees, which can be fixed every
Sanitary welded butterfly valve adopts standard electronic polishing, with smooth surface to ensure cleanness, no media accumulation area, and no potential pollution.Quick disassembly and assembly of valve makes valve opening and maintenance quick and easy, and shortens process shutdown time.The following is a brief introduction to the characteristics and specifications of the sanitary welded butterfly valve, as shown below: ■ The sealing material is aging resistant, corrosion resistant and has a long service life.■ Can
Sanitary pressure transmitter adopts SUS316 stainless steel flange or clamp quick disassembly flat diaphragm structure, which makes the transmitter widely used in bio pharmaceutical, dairy drinks, beer, red wine, chemical, petroleum, power, water supply, pipeline and engineering supporting, industrial pipeline mechanical equipment and other fields safely and efficiently.Flange flat diaphragm and clamp flat diaphragm ensure that the sensor contacts the medium in a large area and is not easy to be stuck by residues
Design and characteristics Plastic handwheel or stainless steel handwheel or solid stainless steel handwheel with external manhole cover Internal surface: mirror surface or internal and external matt external surface: mirror surface polishing, internal and external matt pressure: 0.25 mpa, 0.6 mpa, 1
Hygienic powder butterfly valve is widely used in the bottom of pharmaceutical food, mobile storage tanks, etc. It can be made into manual and pneumatic valves. The valve body materials are SS304, SSS316, and the sealing ring materials meet the requirements of food and pharmaceutical, providing third-party recognition
