Investment Casting Socket
What are Investment Casting Socket?
A Socket, also known as a Coupling, is a cylindrical fitting produced using investment casting, designed to connect two pipes in a straight line. The connection can be made using threaded ends, socket welds, or butt welds, depending on the system’s pressure, temperature, and maintenance needs.
Due to its compact design, smooth finish, and high dimensional accuracy, investment casting sockets are widely used in sanitary, chemical, marine, and precision-engineered fluid systems.
Key Features
- Straight-Line Pipe Connection – Joins two pipes securely in a single direction.
- Multiple End Options – Threaded, socket weld, or butt weld ends available.
- Durable & Pressure-Tight – Designed for high-pressure sealing.
- Corrosion-Resistant Finish – Ideal for aggressive and sanitary fluids.
- Precision Investment Casting – Smooth internal flow and dimensional accuracy.

Do you have questions?
Are sockets available in reducing sizes?
Yes, we manufacture equal, half, and reducing sockets based on project needs.
Can these be used in high-pressure systems?
Absolutely. Investment cast sockets are rated for Class 3000 / 6000, depending on material and wall thickness.
What end types do you offer for sockets?
Sockets are available with threaded, socket weld, or butt weld ends, or combinations thereof.
Are they suitable for sanitary or hygienic applications?
Yes. SS 316L and mirror-polished finishes are available for hygienic use in food and pharma sectors.
