Q:The toilet is made of stainless steel. It is black after wiping. What method?
The toilet is made of ceramic, and he has a thin glaze, which is the white surface that you said. Once the glaze is damaged, it can not be repaired.
Q:What kind of electric stainless steel ball valve is better?
1, fluid resistance is small, the ball valve is the smallest of all types of fluid resistance, even if the diameter of the ball valve, its fluid resistance is quite small2 、 thrust bearings reduce the friction torque of the stem, so that the valve stem can be operated stably for a long time3, the valve seat sealing performance is good, using PTFE and other elastic materials made of sealing ring, the structure is easy to seal, and the ball valve sealing capacity as the medium pressure increases
Q:Good stainless steel ball valve and copper ball valve which is good?
Under the same pressure environment, the price is stainless steel cheaper, and copper ball valve through medium temperature is much higher than stainless steel ball valve
Q:304 stainless steel ball straight through 400
According to some characteristic elements of main chemical components in steel or steel in the classification, divided into chromium stainless steel, chromium nickel stainless steel, nickel chromium molybdenum stainless steel and low carbon steel, stainless steel, stainless steel and high molybdenum high purity; according to the characteristics and application of classification of steel, stainless steel, divided into nitric acid resistant stainless steel, high resistance to sulfuric acid pitting resistance to stress corrosion of stainless steel, stainless steel, stainless steel and other steel; according to the classification features, divided into low temperature stainless steel, non-magnetic stainless steel, stainless steel, stainless steel, free cutting superplasticity. At present, the commonly used classification methods are classified according to the characteristics of the steel structure, the chemical composition of steel and the combination of the two. Generally divided into martensitic stainless steel, ferritic stainless steel, austenitic stainless steel, duplex stainless steel and precipitation hardening stainless steel, etc., or divided into chromium, stainless steel and nickel stainless steel two categories.
Q:How are stainless steel ball valves, shafts and balls linked?
The stem and the ball with bonds, a ball milling groove (sphere a square hole) and the chute (sphere a rectangular hole and through two), stem shape corresponding to the ball slot, plug, turn the stem with rotating sphere.
Q:Does the gate column have stainless steel balls to affect geomantic omen?
Practical, convenient, comfortable, safe, sanitary and beautiful is good feng shui, this is a feng shui master, the general principle is the basic foundation of housing, if these most basic are not, should not be based on Feng Shui; we can further deeper study of Feng shui. To measure by these standards is, indeed, easy to master. Consistent with the above view, positive interpretation of Feng Shui; contrary to the above point of view, Feng Shui interpretation of the negative. The modern housing units are designed, designed and constructed according to the practical, convenient, comfortable, safe, sanitary and beautiful concept. With the ancient "Luo (mule) horse" concept sets, can only be the head of the horse, not the horse mouth.
Q:What about leakage of stainless steel ball valve?
Stainless steel ball valves only need to rotate 90 degrees of operation and small rotating torque can be closed tight. Full equality of the valve cavity for the media to provide a small resistance, through the flow channel. The main features of the valve itself is compact, easy operation and maintenance, stainless steel ball valve can be used to control air, water, steam, all kinds of corrosive media, mud, oil, metals and radioactive liquid media and other types of fluid flow. Ball valve body can be integrated, or can be combination. This kind of valve should be installed horizontally in the pipeline. Stainless steel ball valve classification: stainless steel pneumatic ball valve, stainless steel electric ball valve, stainless steel manual ball valve. Stainless steel ball valve is divided into 304316321 stainless steel ball valve.
Q:What's the inside diameter of DN50 stainless steel ball valve?
This is not a fixed value, in different conditions, material temperature, pressure, ratings are different, in general, the default 50mm
Q:How can I remove the PVC from the waste stainless steel? No fire
The apple peel or hawthorn (broken) water (not charred place) in the fire to cook, black not less severe for a while, it will cook too dark. The water is cold. Just scrub it with a clean cloth. Because the burnt part belongs to the alkaline substance. The apple peel water is acidic, and the acid and base pot is clean. Do not use stainless steel ball, it will wipe the surface of the pot.
Q:420 stainless steel and martensitic stainless steel that kind of good?
420 stainless steel is the "cutting class" martensitic steel, similar to Brandt's first high chromium stainless steel this. 420, a certain resistance to wear and corrosion resistance, higher hardness, the price is stainless steel ball in the lower class, applicable to the general requirements of stainless steel working environment. 420 stainless steel applies to all kinds of precision machinery, bearings, electrical, equipment, instruments, meters, transportation, household appliances, etc.. Often used in manufacturing atmospheres, steam, water, and oxidizing acid corrosion parts.
