1. Product Features

Compact structure: The socket design of the socket flange provides a tight connection surface, which increases the contact area between the pipe and the flange, thereby enhancing the welding strength.

Suitable for high-pressure environment: The socket flange has good pressure resistance and is often used in pipeline systems that withstand high pressure.

Stable welding method: Through socket welding, the combination of the pipe and the flange is very firm, which can effectively reduce the risk of leakage and ensure the sealing of the system.

High sealing: The socket flange is often used in systems that require strict sealing due to its deep and strong welding point to ensure that no leakage occurs.

Good corrosion resistance: Socket flanges are usually made of corrosion-resistant materials (such as stainless steel, alloy steel, etc.) and are suitable for pipeline connections of various media.

Suitable for small-diameter pipelines: Socket flanges are often used for small-diameter pipelines (generally DN15 to DN150), especially in high pressure and high sealing requirements.

2. Product type

Standard socket flange: It meets common national and international standards (such as GB, ANSI, DIN, JIS, etc.) and adapts to different pipeline connection needs.

Long-neck socket flange: has a longer flange neck, provides higher connection strength and sealing performance, and is suitable for systems with higher pressure or special media.

Blind socket flange: used to close openings in the piping system to prevent media leakage, and has the same characteristics as the standard socket flange.

4. Material selection

Carbon steel: suitable for conventional pipeline systems, economical and durable, and can withstand conventional pressure and temperature.

Stainless steel: strong corrosion resistance, suitable for chemical, food, pharmaceutical and other industries, and can resist a variety of acids, alkalis and chemical media.

Alloy steel: suitable for high temperature and high pressure environments, can withstand extreme working conditions, and is widely used in oil and gas, electricity and other fields.

5. Application areas

Oil and gas industry: used in high-pressure pipeline systems, such as oil and gas transmission pipelines.

Chemical industry: used for the connection of pipelines such as chemicals and corrosive media.

Power industry: suitable for the connection of boilers, steam pipes and cooling systems in power plants.

Shipbuilding and marine engineering: Socket flanges are also widely used in high-pressure environments such as offshore platforms and ships.

Food and pharmaceutical industries: Because stainless steel socket flanges have good corrosion resistance and hygiene, they are suitable for use in the food and pharmaceutical industries.

6. Installation and use

Installation method: The installation of the socket flange is relatively simple. Insert the pipe into the socket of the flange and weld it. After welding, the flange and the pipe are tightly combined.

Welding requirements: When welding, it is necessary to ensure that the flange and pipe surfaces are clean to avoid impurities affecting the welding quality. After welding, the quality of the weld should be checked to avoid problems such as cracks and leaks.

Check the sealing: After installation, a pressure test should be performed to ensure that the connection of the socket flange is well sealed and there is no leakage.

7. Quality Assurance

Precision processing: The socket flange uses precision processing equipment during the manufacturing process to ensure that the flange size is accurate and the socket depth is appropriate to ensure the welding quality.

Material inspection: All flange materials have undergone strict material inspection and meet the requirements of relevant standards to ensure their stable performance.

Factory inspection: Each batch of products will undergo strict pressure testing, welding strength inspection, etc. to ensure that they meet the use standards.

Warranty period: Most manufacturers provide a 12-month warranty period, during which quality problems can be repaired or replaced free of charge.

8. Packaging and transportation

Packaging method: According to the size and quantity of the product, it is usually packed in wooden boxes, bubble film or pallets to ensure that the product is not damaged during transportation.

Transportation mode: It can be transported by road, rail, sea and other modes to ensure timely delivery.

9. Price and customization

Price: The price of socket flange is affected by many factors such as material, specification, pressure level, etc., and is usually more expensive than other types of flanges.

Customization service: Socket flanges with non-standard sizes, special materials or special pressure levels can be customized according to customer requirements to meet the needs of various special working conditions.

10. Summary

The socket flange has become a common and important connector in high-pressure pipeline systems due to its superior sealing, pressure resistance and scope of application. It is particularly suitable for the connection of small-diameter high-pressure pipelines. It has the advantages of firm welding and strong sealing, and is widely used in many fields such as petroleum, chemical industry, and electric power. Choosing a suitable socket flange can not only improve the safety of the pipeline system, but also ensure the long-term stable operation of the system.
