Q:What's the difference between the water supply U-PVC plastic pipe and the UPVC plastic pipe?

U-PVC plastic pipe and UPVC pipe without distinction, just writing methods are not the same, it refers to the rigid PVC pipe, UPVC water supply pipe is a sanitary PVC (PVC) resin as the main raw material, adding non-toxic stabilizers, lubricants, fillers, coloring agent by plastic extruder pipes and fittings molding and injection molding machine injection molding production etc.. The regular UPVC plastic tube formula has no hygienic requirement, and some additives are harmful to human body.

Q:An air core is no core except air.

The purpose of a core in a transformer is to ensure as much as possible of the flux from one winding links the other. Also, we want the core to have a very small reluctance, so that the magnetising inductance (sometimes refered to as the mutual inductance) is very large. If it isnt, the transformer will have a large magnetising current i.e. it behaves as a shunt low value inductance, we need this inductance to be very high. Even if the powdered stones in the tube had a low reluctance (maybe they have alot of iron oxides in them?), the problem is that still most of the magnetic circuit is through air, so there is still a high reluctance. You need a closed magnetic circuit with a low reluctance material, or else you will need a very large number of turns on the windings, and they will need to be arranged carefully, to keep the leakage inductance low (flux from one winding that doesnt link with the other...) But what is the application? For low frequency power transformers we want a low leakage reactance and a very high magnetising reactance. For other kinds of transformers we might want a high leakage reactance (say a transformer to be used as a welder, the leakage reactance acts like a series choke to limit the short circuit current...). For broadband high frequency transformers, we want as little leakage inductance as possible, where as low magnetising inductance is not a problem at these frequencies. So usually we make transformers for this application with the two windings as one side of a twisted pair cable, or coax cable, and then have an air core. So how good a transformer core is depends on its application!

Q:There are several kinds of domestic water pipes

Is the water in the first-class goods, in order to sort the copper chemical activity is very low, but also by hydrogen, and stable performance, easy corrosion. According to relevant data, copper can inhibit the growth of bacteria, and keep the drinking water clean and sanitary.Advantages: high strength, stable performance, bactericidal, and not easy to corrosion.Disadvantages: high prices, difficult construction, cold in the winter, it is easy to cause heat loss, energy consumption, high use costs.

Q:Can plastic tubes be used for storing powders or granules?

Yes, plastic tubes can be used for storing powders or granules. Plastic tubes are commonly used for this purpose due to their durability, versatility, and ability to protect the contents from moisture and contamination. They are available in different sizes and shapes, making them suitable for storing a wide range of powders or granules.

Q:How do you prevent plastic tubes from discoloration?

To prevent plastic tubes from discoloration, you can try a few methods. First, ensure that the tubes are stored in a cool and dry place away from direct sunlight, as exposure to heat and UV rays can cause discoloration. Additionally, avoid contact with chemicals or substances that may react with the plastic. Regular cleaning using mild soap and water can also help maintain their original color.

Q:Hello I want to buy a leather storage tube for my A1 sized drawings. I'm studying architecture and I want something a bit more classy than the plastic tubes I have found. Does anyone know where I can buy one?

Cost Was this what you were looking for?

Q:What is the maximum diameter of plastic tubes available?

The maximum diameter of plastic tubes available can vary depending on the manufacturer and the specific application, but it can typically range from a few millimeters to several inches.

Q:How much is the pipe digging face?

The working characteristics of directly mining minerals or rocks are moved along with the progress of excavation.Parts machined by parts.Working face (lighted) usually refers to the work place, where there is a standard and to the illuminance measurement. Unless specifically stated, it is generally assumed to lie on the horizontal surface 0.76 meters (30 inches) above the floor.

Q:How can the plastic pipe fall into the throttle valve?

The valve on the throttle is basically a vacuum tube, one is EGR (waste gas recirculation), the two is the brake vacuum drum vacuum, and the three is the cold car speed
