Flanges by Types
The different types of common flanges include Weld Neck (WN) flange, Slip-On (SO) flange, Threaded flange, Socket Weld (SW) flange, Lap Joint (LJ) flange, and Blind (BL) flange. These flange types serve different functions in various piping system applications. SSM offers these common flange types, as well as customized products to meet specific requirements.
Weld Neck Flanges
Our weld neck flange is specifically designed for butt-welding with pipes, delivering superior strength and reducing stress concentration. It is the ideal choice for high-pressure, high-temperature, and corrosive environments.
Slip-On Flanges
With a slightly larger inner diameter than the outer diameter of the pipe, our slip-on flange allows for easy insertion and welding. Perfect for low-pressure environments, it offers effortless installation.
Threaded Flanges
Our threaded flange, featuring inner hole threads, eliminates the need for welding when connecting to the pipe thread. It is the perfect fit for small-diameter and high-pressure systems, especially in hazardous areas.
Socket Weld Flanges
Designed with a socket inside the flange for easy pipe insertion, this type is ideal for small-diameter and high-pressure systems, providing unmatched fatigue strength.
Lap Joint Flanges
Paired with the lap joint short section (Stub End), our lap joint flange allows for free rotation on the pipe. It is the ideal solution for pipeline systems that demand frequent disassembly and assembly, particularly for use with corrosive media.
Blind Flanges
The Blind Flange provided by SSM has no holes and is used to close pipe ports or equipment openings. It is used for pipe ends, inspection holes, and pressure testing.
Industry SSM Flanges Serve
SSM’s flanges are widely used in various industrial fields, primarily for connecting pipelines, equipment, pressure vessels, pumps, valves, and other interfaces. Some specific application scenarios include:
Oil and gas industry
SSM’ Flanges are used to connect pipelines and equipment in oil field mining, natural gas processing, and transmission pipelines to ensure system sealing and safety.

How to Make Flanges
Flanges can be categorized based on the production process. Each process method has specific advantages and is suitable for different application requirements. The table summarizes the characteristics, main steps, advantages, disadvantages, and application scenarios for each flange production process.
| Process type | Features | Main steps | Advantages | Disadvantages | Application |
| Forging process | Manufactured by heating and forging plastic deformation | 1. Heating 2. Forging 3. Cooling 4. Machining | High strength, good toughness, dense structure | High equipment and process requirements | High pressure, high temperature and high corrosion environment |
| Casting process | Melt the metal and pour it into the mold to cool and shape | 1. Melting 2. Pouring 3. Cooling 4. Cleaning 5. Machining | Low cost, suitable for manufacturing large flanges with complex shapes | Rough structure and poor mechanical properties | Low pressure and occasions with low mechanical properties |
| Cutting process | Cut steel plates or forgings directly into the required shape | 1. Cutting 2. Machining | Simple process, suitable for small and medium-sized flange production | Not suitable for high pressure and high temperature environment | Low pressure, medium and low pressure pipeline connection |
| Rolling process | Roll metal sheets or round bars into shape through rolling equipment | 1. Rolling 2. Cutting 3. Machining | Suitable for mass production and high production efficiency | High material requirements, mainly used for small and medium diameter flanges | Medium and low pressure pipeline connection |
