جریان آب آب تشکیل شده از دو گاز هیدروژن و اکسیژن به نسبت دو ملکول هیدروژن و یک ملکول اکسیژن (H2O). در سیستم انگلیسی آب در فشار جو در دمای ۲۱۲ درجه فارنهایت به جوش می آید و در دمای ۳۲ درجه فارنهایت یخ میزند. بیشترین وزن مخصوص در دمای ۳۹٫۱ درجه فارنهایت به ازای هر فوت مکعب ۶۲٫۴۲۵ پوند(LP) میباشد. (یک پوند=۴۵۳٫۵g گرم) .درسیستم متریک آب تحت فشار جو در دمای ۱۰۰ درجه سانتی گراد بجوش می آید. و در دمای صفر درجه سانتی گراد یخ میزند. وزن مخصوص یک لیتر آب یک کیلوگرم است. در حالیکه یک لیتر یک دسیمتر مکعب میباشد. در سیستم متریک فشار برحسب پاسگال (Pa) که معادل یک نیوتن بر مترمربع است. در دماهای بالاتر فشار

Lubricants and Lubrication   A lubricant is used for one or more of the following purposes: 1.To reduce friction: 2.To prevent wear: 3.To prevent adhesion: 4.To aid in distributing the load: 5.To cool the moving elements: and 6.To prevent corrosion. The range of materials used as lubricants has been greatly broadened over the years so that in addition to oils and greases many plastics and solids and even gases are now being applied in this role . The only limitations on many of these materials are their ability to replenish themselves , to dissipate frictional heat ,their reaction to high

Pinch valve made by AHANGARY in China is a new type of valve with unique structure. It is very popular because of its excellent wear resistance and corrosion resistance. It is suitable for the transportation control of granular slurry or chemical medium in various pressure pipelines system. Basic Character: Scope of application: Chemical industry, petroleum, power generation, alkali plant, mineral processing, cement coal preparation, non-metallic industries. It can quickly control or cut-off sand flow pipeline. Applicable media: pulp, sewage, slag, cinder, sediment and so on. Applicable temper

Water Pressures : Water is composed of two gases , hydrogen and oxygen , in the ratio of two volumes of the former to one of the latter . In the English System of measure , water boils under atmospheric pressure at 212 degrees F . and freezes at 32 degrees F. Its greatest density is 62.425 pounds per cubic foot , at 39.1 degrees F . In metric SI measure water boils under atmospheric pressure at 100 degrees C (Celsius) and freezes at 0 degrees C . Its density is equal to one kilogram per liter , where one liter is one cubic decimeter.also in metric SI , pressure is given in pascals (Pa) or the

rubber line pumps Burly rubber lined pumps are less expensive then more exotic stainless steel and high alloy pump for indentical service condition. Simple external axial adjustment for impeller adjustments. Centrifugal single stage / back pull out design. Standard dimensions cut layout design cost. Contact part are lined with hard ebonite (natural rubber). Heavy and sturdy construction. Pumps can be arranged for a v – belt drive or direct coupled from a motor mounted on a common base frame. Sealing Options: Gland Packing Performance Data: Model Suction mm Delivery mm Imp.Dia. mm H.P. RPM Head

  Optimize production and mitigate corrosion through effective liquids sweeping and debris removal • Reduce emissions by more than 80% compared to traditional launching method • Signifi cantly smaller footprint reduces the space required for pigging facilities • Reduced requirement for infrastructure decreases fi eld construction time • Functionally simple design minimizes training and maintenance costs • Double block and bleed construction facilitates use as a traditional block valve, thus reducing the number of valves required in the pigging facility • Built in features enhance safety f
