Product DescriptionZhengde Classification of flanges1. Divide
carbon steel, cast steel, alloy steel, stainless steel, copper,
aluminum alloy by material2. According to the production method, it
can be divided into forged flanges, cast flanges, welded flanges,
etc.3. According to manufacturing standards, it can be divided into
national standards (Ministry of Chemical Industry standards,
petroleum standards, electric power standards), American standards
(ASTM), German standards (DIN), Japanese standards (JB), etc.my

surface RJFlange applicationButt welding steel flange: used for
butt welding of flanges and pipes. It has a reasonable structure,
high strength and steel, can withstand high temperature and
pressure, repeated bending and temperature fluctuations, and has
reliable sealing performance. The butt welding flange with a
nominal pressure of 0.25-2.5Mpa adopts a concave and convex sealing
surface.Flat welded steel flange: suitable for carbon steel pipe
connections with nominal pressure not exceeding 2.5Mpa. The sealing
surface of flat welding flange can be made into three types: smooth
type, concave and convex type and tongue and groove type. The
smooth flat welding flange has the largest application volume and
is mostly used when the medium conditions are relatively mild, such
as low-pressure non-purified compressed air and low-pressure
circulating water. Its advantage is that it is relatively
cheap.Socket welding flange: commonly used in pipelines with
PN≤10.0Mpa, DN≤40;Loose flange: Loose flange is commonly known as
loop flange, divided into welding ring loop flange, flanged loop
flange and butt welding loop flange. It is often used in situations
where the medium temperature and pressure are not high but the
medium is highly corrosive. When the medium is highly corrosive,
the part of the flange that contacts the medium (the flanged
nipple) is made of corrosion-resistant high-grade materials such as
stainless steel, while the outside is clamped by a flange ring of
low-grade material such as carbon steel. to achieve
sealing;Integral flange: The flange is often integrated with
equipment, pipes, valves, etc. This type is commonly used on
equipment and valves.Our Advantages Quality first:
production and inspection in strict accordance with production
standards;Price advantage: discounts based on real market
prices;Transaction security: There will be no loss of customer
funds;After-sales guarantee: the customer's problem is our
problem;Long-term cooperation: quality assurance, price advantage,
sincere service can last for a long time.Detailed PhotosPackaging &
