Standardization ensures safety and compatibility in the vast landscape of global industries. It facilitates international trade by providing a common ground for manufacturers, suppliers, and end-users. This article delves into the classifications of standard flanges in different countries, shedding light on their unique features and applications.
ANSI flange In the United States, ANSI (American National Standards Institute) flanges are widely used. ANSI B16.5 and ANSI B16.47 are two common standards, each with its specifications. The former is suitable for nominal pipe sizes from 1/2" to 24", while the latter covers larger sizes.
Din flange Germany follows the DIN (Deutsches Institut für Normung) standards for flanges. DIN and DIN are notable specifications, offering precision and reliability. DIN is designed for nominal pressure ratings, while DIN focuses on welding neck flanges.
JIS flange Japan adheres to the JIS (Japanese Industrial Standards) for flanges. JIS B and JIS B provide detailed specifications for different types of flanges. B covers steel pipe flanges, while B focuses on hydraulic fluid power - flange connections.
BS flange British industries follow BS (British Standards) for flanges. BS 10 and BS are prominent standards, with BS 10 emphasizing on nominal sizes and BS providing specifications for circular flanges.
Australia adopts AS (Australian Standards) for flanges. AS and AS are commonly referenced standards, with AS covering table flanges and AS focusing on Class PN14 and PN16 flanges.
Russian industries adhere to GOST (Gosudarstvennyy Standart) standards for flanges. GOST and GOST are noteworthy, with GOST concentrating on butt-welded flanges and GOST covering plate flanges.
China follows GB/T (Guobiao) standards for flanges. GB/T and GB/T are commonly used, with GB/T specifying welding neck flanges and GB/T covering plate flanges.
Italy adopts UNI (Ente Nazionale Italiano di Unificazione) standards for flanges. UNI and UNI are notable, with UNI covering slip-on flanges and UNI providing specifications for welding neck flanges.
When comparing standard flanges from different countries, variations in materials, pressure and temperature ratings, and sizes become evident. It's crucial to understand these differences to ensure the proper selection of flanges for specific applications.
It is a kind of filter that directly intercepts impurities in the water, removes suspended solids and particulate matter in the water body, reduces turbidity, purifies water quality, reduces system fouling, algae, rust, etc., so as to purify water quality and protect the normal operation of other equipment in the system. equipment.
The main components are: motor, electric control box, control pipeline, main pipe assembly, filter element assembly, 316L stainless steel brush, frame assembly, drive shaft, inlet and outlet connection flanges, etc. The self-cleaning flanged y strainer can filter the raw water, And the function of cleaning the filter element automatically.

When cleaning and discharging sewage, the system provides uninterrupted water supply, which can monitor the working state of the filter and has a high degree of automation. Covers the needs of various filtration precisions from 10 microns to microns.
Adopting the advanced technology of international water treatment industry equipment, it can be installed vertically, horizontally, or upside down in any direction and in any position. water filtration.
It is composed of shell, multi-element filter element, backwash mechanism, electric control box, reducer, electric valve and differential pressure controller.
The diaphragm in the shell divides its inner cavity into upper and lower cavities, and the upper cavity is equipped with multiple filter elements, which utilizes the filter space and significantly reduces the filter volume, and a backwash suction cup is installed in the lower cavity.
When working, the turbid liquid enters the lower cavity of the flange type of the automatic filter through the inlet, and then enters the inner cavity of the filter element through the baffle hole. Export sent.
Advantages: The automatic filtration precision is 100 microns by default, and can be selected from 10 to microns. The filter area is large and the dirt holding capacity is high. Users can customize it according to the actual working conditions.
The cleaning method is simple, and the cleaning cycle is electronically monitored, which can realize automatic cleaning and sewage discharge. All parameters in the automatic self-cleaning filter control system can be adjusted, etc.
The main function of the brush type flange filter is to remove the suspended solids in the water, reduce the concentration of suspended solids in the water, reduce the particulate matter, reduce the turbidity, purify the water quality, reduce the system fouling, bacteria and algae, rust, and purify the water quality.
It can easily and thoroughly remove the impurities retained by the filter screen, with no dead ends and no flux attenuation, which ensures the filtration efficiency and long service life of the brush flange filter.
Through its own retrieval and strain functions, automatic backwashing is realized, and the brush-type flanged y strainer can cope with unstable water quality fluctuations without manual intervention.
During the backwashing process, each (group) filter screen will be backwashed in turn to ensure that the filter screen is cleaned safely and efficiently, while other filter screens are not affected and continue to filter.
The brush type flanged y strainer adopts an automatic drain valve, which saves time for backwashing, consumes less water for backwashing, and is environmentally friendly and economical. Fewer wearing parts, no consumables, low operation and maintenance costs, simple operation and management
