DESCRIPTION

Description

AIM-D100 type products are mainly used for monitoring of the positive and negative terminal-to-ground insulation resistance in the DC ungrounded systems. When the insulation resistance is lower than the set alarm value, an alarm message can be sent. The product is based on the unbalanced bridge principle.

The products can be used in DC systems such as DC EV charging systems, PV Solar systems, energy storage systems, and DC power grids.

DC Insulation Monitor


Product Summary:

Used for connection between pipe ends; Also useful is a flange on the inlet and outlet of the equipment, used for connecting between two devices, such as a gearbox flange. Flange connection or flange joint refers to a detachable connection consisting of flanges, gaskets, and bolts connected to each other as a combination sealing structure. Pipeline flange refers to the flange used for piping in pipeline devices, and when used on equipment, it refers to the inlet and outlet flanges of the equipment. There are holes on the flange, and bolts make the two flanges tightly connected. Seal the flanges with gaskets.

Classification:Butt welded pipe fittings

Keywords: Butt welded pipe parts

产品详细

There are GB series (national standard), JB series (mechanical department), HG series (chemical department), ASME B16.5 (American standard), BS4504 (British standard), DIN (German standard), JIS (Japanese standard).

 

Advantages:

 

The on-site installation is more convenient, and the process of welding seam rubbing can be omitted

 

Disadvantages:

 

The neck height of the flat welded flange with a neck is relatively low, which improves the stiffness and load-bearing capacity of the flange. Compared with butt welded flanges, the welding workload is large, the consumption of welding rods is high, and it cannot withstand high temperature and pressure, repeated bending, and temperature fluctuations.

 

The connection is not easily deformed, with good sealing effect, and is widely used. It is suitable for pipelines with significant temperature or pressure fluctuations, as well as pipelines with high, high, and low temperatures. It is also used for transporting expensive media, flammable and explosive media, and toxic gases
