Biphasic steel flange is a biphasic steel bar steel ingot or plate as raw materials and produced flange, referred to as biphasic steel flange, flange is also known as flange or flange. The following is the introduction of dual-phase steel flange application principle for launching steam.
The water steam that is pumped out should be compressed in the compressor room until the exhaust valve opens and stops. If it is assumed that the temperature in the pump is 60℃, then the full steam pressure in the water at this temperature is 20000 pa. Once the water steam in the contraction process reaches the above pressure, it will begin to condense into water, but 20000 pa also push the exhaust valve. Because the exhaust valve is to the atmosphere and the exhaust valve spring pressure, that is, the internal pressure of the pump chamber to tighten to more than 120,000 mpa to open the exhaust valve, water steam contraction in the future, to the late contraction has all condensed into water, and mixed into the vacuum pump oil.
Two - phase steel flanges are pipe - to - pipe interconnecting parts. Connected to tube end. There are holes on the flange, and bolts can be worn to make the two flanges tightly connected. The flanges are gasketed. The flange connection consists of a pair of flanges, a gasket and a number of bolts and nuts.
The gasket is placed between the sealing surface of the two flanges. After tightening the nut, the specific pressure on the surface of the gasket deforms after reaching a certain value, and fills the uneven part of the sealing surface, so that the connection is tight and does not leak. Some pipe fittings and equipment now come with flanges, also attributed to flange connection. Flange connection is the main connection method in pipeline construction.
Because of these advantages of duplex steel flanges. Is widely used in all kinds of sewage treatment pipes.. Deep sea industry. Seawater desalination. Paper industry equipment, food industry processing equipment, offshore oil channels (heat exchanger pipe, water treatment and water supply system) desalination (desalination) equipment, oil field pipeline and equipment, all kinds of acid and alkali environment. Because of the outstanding wear and corrosion resistance
