About SS400 Carbon Steel Long Weld Neck Flange

Elite Piping Manufacture Co., Ltd manufactures and supplies flanges, pipe fittings, and line pipes. We specialize in SS400 carbon steel long weld neck flanges. If you need anything, please feel free to contact us.

Carbon steel weld neck flange is a type of pipe fitting, which refers to a flange with a neck and a round pipe transition and is butt welded to the pipe. The butt welding flange is a disc-shaped part, which is the most common in pipeline engineering. Flanges are used in pairs. In pipeline engineering, butt welding flange is mainly used for the connection of pipelines.

Many customers have recognized our carbon steel long weld neck flange. If you need it, our company’s products are your best choice. Welcome everyone to communicate with Elite Piping Manufacture.

SS400 Carbon Steel Long Weld Neck Flange  Composition

The carbon steel flange consists of 2 900 clamping base plates, 2 flange plates, two vertical plates, and four stiffening plates. The connecting plate’s welding joint should be welded through the groove with a 20-30mm welding angle to ensure the tool’s rigidity.

SS400 Carbon Steel Long Weld Neck Flange Connection Method

SS400 carbon steel flange connections should maintain the same axis, and the center deviation of the screw holes should generally not exceed 5% of the hole diameter, and free penetration of the screws should be ensured. The connecting screws of carbon steel flanges should be of the same specification and the installation direction should be the same. The screws should be tightened evenly.

SS400 Carbon Steel Long Weld Neck Flange Classification

SS400 carbon steel long weld neck flange is divided into neck-to-welded, neck welding, inheritance welding, and thread flange. Generally made of forgings or forging process systems.

SS400 Carbon Steel Long Weld Neck Flange Product Process

All of our convex welding neck flanges are forged. The forging process generally includes the following: choosing high-quality billets, heating, forming, and cooling after forging. Forging process methods include forging, mold forging, and membrane forging. During the production process, different forging methods are selected based on the quality and quantity of forging.

The advantage of forging flanges is that their internal structure is uniform, the casting has no pores, and there are no harmful defects.

Sealing Surface Type

The sealing surface types include basic types such as flat, raised, concave, and convex surfaces, tongue-and-groove surfaces, and ring connection surfaces with blue covers.

Manufacturing Process

The forging process and casting process mainly makes neck butt welding flange. We mostly choose the forging process. This method has lower carbon content than the casting process, is less prone to rust, has a better-streamlined shape, and has good mechanical properties.

Neck flat welding flange is used for butt welding of flanges and pipes. It has a reasonable structure, high strength and rigidity, can withstand high temperature and pressure, repeated bending and temperature fluctuations, and has reliable sealing performance.

Advantages

Carbon steel flange is high-resistant, strong anti-pressure resistance

Carbon steel flange is used for long-lasting years: it can prevent UV light and radiation prevention

Good erosion resistance of carbon steel: acid resistance, alkali resistance, strong corrosion resistance, not rust, will not erode, will not breed bacteria, and have no electrochemical erosion.

Carbon steel flange has good heating and good heat resistance

Operating Principle

The carbon steel long weld neck flange working principle is to use carbon steel flange gasket insulation gasket insulation performance high-strength carbon steel flange insulation, and carbon steel flange on both sides of the electrical insulation flange factory to work. Mary iron is commonly used with galvanized pipes (energy-saving iron) and is stronger than steel and stronger than iron.

 Application

It can work in highly corrosive or high-temperature environments. Welding neck flanges can be used for various applications, including petroleum and natural gas pipelines, chemical processing facilities, etc. These flanges are suitable for various pipelines, including carbon steel, stainless steel, and other alloys. We provide various sizes and rated pressures so you can find the perfect flange that meets your needs.

SS400 Carbon Steel Long Weld Neck Flange Maintenance Service

SS400 carbon steel long weld neck flanges can damage the end face or sealing groove during long-term production and operation, resulting in leakage accidents.

Slinlik flange repair technology and high-precision, fully automatic professional equipment completely eliminate leakage points and leave no safety hazards. The repair time is short; polymer composite materials can be repaired directly on-site to make the sealing surface meet the technical requirements of sealing, reducing disassembly, transportation time, and costs.

After-Sales Service

We will maintain close contact with customers after the products are sold. Customers can provide feedback on product problems to us through various methods such as phone calls, emails, and website messages. We will solve customers’ problems as soon as possible. Develop corresponding solutions including but not limited to repair, product replacement or refund to ensure customer satisfaction.

Other Services

We will promptly inform customers about product updates and upgrades to ensure that customers can purchase the highest-quality products. We will also have corresponding preferential services, which are incredibly cost-effective.

Precautions

The steel should be cut into strips along the rolling direction, bent, and butt welded into a ring, and the surface of the steel should form the cylinder of the ring. Steel plates must not be directly machined into necked flanges.

The steel plate should undergo ultrasonic flaw detection and have no delamination defects;

The butt welds of the rings should be complete penetration welds; when stainless steel bolts are used, insulating gaskets and sleeves must be added.
