PRODUCT OVERVIEW
Flange Types We Supply
We supply industrial flanges and related forgings for piping, valves, pumps and equipment. Products are manufactured to international standards with traceable material and NDT. Standard identification on flanges and packing (e.g. Class 150-8, DN 25, DN 20) supports correct selection and delivery.
MAIN FLANGE TYPES
| Type | Name | Description |
|---|
| Threaded Flange | TH | Threaded bore for screw connection to pipe; no welding. |
| Plate Flange | Plate | Flat ring with centre bore and bolt holes; simple slip-on style. |
| Slip-On Flange | SO | Slips over pipe; fillet weld both sides. Common for lower pressure. |
| Welding Neck Flange | WN | Tapered hub butt-welded to pipe; best for high pressure and critical service. |
| Long Weld Neck Flange | LWN | Extended neck for vessel nozzles and special layouts. |
| Blind Flange | BL | Solid disc to close pipe end; same bolt circle as matching flanges. |
| Socket Welding Flange | SW | Pipe inserted into socket and fillet welded; compact. |
| Special Flange | Special | Non-standard dimensions or geometry to order. |
Wind power flanges, flange packing (gaskets), and ring forgings for custom machining are also available. Material grades: see specification page.
FLANGE PRODUCTS
Finished flanges — storage and dispatch
Silver metal flanges with blue protective caps or gaskets; Class 150-8, 150-4, 300-2, DN 25, DN 20 and other sizes. High-finish surfaces, clean packing, ready for export.
SCALE & MANUFACTURING
Large flanges and forging process
Large-diameter flanges for heavy piping; hot forging of flange blanks for strength and integrity.
