Good Quality Alloy Steel Flange with SGS

Precision alloys are known for their unique physical and mechanical properties, making them ideal for critical components in precision motors, electrical appliances, instruments, telecommunications equipment, and precision machinery.

These alloys are categorized based on their applications and characteristics, including hard magnetic alloys, magnetically soft alloys, elastic alloys, expansion alloys, thermo-bimetal, resistance alloys, thermocouple alloys, electric conduction alloys, electric contact alloys, shape memory alloys, and superconducting alloys.

Types' Specification
Welding Neck
1. Preferred for high-pressure, subzero or elevated temperature
2. Hub is tapered and bored to match the pipe's inside diameter, ensuring smooth flow and reducing turbulence and erosion
3. Easy to radiograph and provides excellent stress distribution
Slip-On
1. Not typically used in high-stress applications due to low hub and weld attachment
2. Slips over the outside of the pipe
3. The inside of the flange is welded at the hub and the end of the pipe
Lap Joint
1. Used where bolt alignment or access for cleaning is required
2. Similar to slip-on flange when used with lap joint stub end
3. Radius at the intersection of the flange face and bore matches the lap joint stub end
Threaded
1. Used where welding would be hazardous
2. Designed for low-pressure and non-cyclic applications
3. Bore is threaded to match the pipe thread
4. Tapered to seal the pipe and flanges
Socket Welding
1. For small-diameter chemical processes, hydraulic and steam distribution lines
2. Similar to slip-on flange
3. Counterbore matches the pipe bore, allowing unrestricted flow
4. Counterbore from the hub side fits the pipe's outer diameter - can insert the pipe in the socket with a fillet weld at the hub
Blind
1. Used to close ends of piping
2. Has no bore
3. Permits access to sealed lines
