Socket flange

Sliding flange

Carbon steel flange, that is, the flange or end flange connection whose body material is carbon steel. The flanges containing carbon steel are called carbon steel flanges. Common materials are cast carbon steel grades WCB, forgings A105, or Q235B, A3, 10#, #20 steel, 16 manganese, 45# steel, Q345B, etc.

The connection method of the national standard flange!

Another meaning of the national standard flange is: the flange plate produced according to the size and tolerance range required by the national standard is different from the flange sheet produced not according to the standard size, which is also called the second standard flange (some people call it non-standard flange). is incorrect), usually some unscrupulous merchants will reduce the flange thickness and outer diameter to save materials, and use scrap steel or scrap steel to process flanges, usually this kind of steel is chemical composition and mechanical Scrap whose performance does not meet the standard, and even the use of private steelmaking in black steel plants to produce flanges. The steelmaking technology used in this private steelmaking is outdated and cannot guarantee mechanical properties and welding performance. It may not be able to be welded with steel pipes during use, or The steel itself has cracks, pores, etc., and it will leak water after welding.

How to determine the quality of carbon steel flanges?

The shape and size of carbon steel flanges are accurate, the processing volume is small, and the cost is low. However, the casting flange will have holes, cracks and impurities, and the internal structure of the casting is poor. It has the advantage that it can have more complex shapes and is low cost to produce. Because the carbon content of ordinary carbon steel flanges is lower than that of cast flanges, it is not easy to rust and has a dense structure. They can withstand shear and tensile forces better and have better mechanical properties than forged flanges. Ordinary carbon steel flanges and cast flanges are difficult to distinguish from appearance alone. When purchasing carbon steel flanges, they must be selected according to the usage environment. Not just cheap, but premised on it. Flange storage should not be placed directly on the ground. Put some damp pads on the ground and line up the flanges neatly. When placing them, leave a channel between the carbon steel flange and the carbon steel flange. It plays the role of ventilation and also facilitates the transportation of carbon steel flanges. Different materials should be stored and marked separately. The same material, materials of different types and specifications should be stored separately, and the corresponding markings should be stacked neatly to avoid bumps.

Standards and requirements for carbon steel flanges!

Carbon steel flanges are produced in accordance with the size and tolerance range required by national standards. They are different from flanges that are not produced according to standard sizes, also called second-standard flanges (some people call non-standard flanges incorrect). Usually, some unscrupulous merchants will reduce the thickness and outer diameter of the flange to achieve the purpose of saving materials, and also use scrap steel or scrap steel to process the flange. Usually this kind of steel is waste material whose chemical composition and mechanical properties do not meet the standards. What’s more, the flanges are produced by private steelmaking in black steel plants. The steelmaking technology used in this private steelmaking is outdated and cannot guarantee the mechanical properties and welding properties. From time to time, it may not be possible to weld with the steel pipe, or the steel itself will leak water after welding with cracks and pores. Therefore, try to use carbon steel flanges when purchasing flanges.

The technical advantages of carbon steel flanges!

Another layer of carbon steel flanges means: flanges produced according to the size and tolerance range required by national standards are different from flanges not produced according to standard sizes, also called second-standard flanges (some people call them non-standard methods). The flange is incorrect), usually some unscrupulous merchants will reduce the thickness and outer diameter of the flange to save materials, and use scrap steel or scrap steel to process the flange. Usually this kind of steel is waste material whose chemical composition and mechanical properties do not meet the standards. What’s more, the flanges are produced by private steelmaking in black steel plants.

Therefore, try to use carbon steel flanges when purchasing flanges.

CUSTOM PROCESSING

Various special flanges or metal products can be customized according to customer requirements and drawings

Thermal processing

The natural gas heating furnace with continuous operation of the heating furnace is accurate and efficient, so that the block can be heated to a suitable temperature for forging.

Forging hammering

The forging production line composed of air hammer, ring rolling machine and press machine is suitable for the manufacture of multiple specifications and small quantities in the flange industry.

Machining

The high-efficiency production of full CNC machining not only ensures the surface finish, but also makes the product size more accurate.

Rustproof

The surface of the flange that has been machined is subjected to anti-rust treatment. The common methods are oiling, painting, galvanizing and nitrous acid.

Package

The thick enough plate ensures the solidity of the wooden box, and each layer of flanges uses partitions to prevent collisions.
