Pipe Joints
- Standard Push-on joint:
SADIP designs its standard push-on joints to create a secure, leak-proof seal. As water pressure increases, the gasket compresses against the metal, ensuring a tight connection.
- Advantages:
- Easiness of assembly
- Allowable Joint Deflection
SADIP socket – spigot joints permit angular deflection which gives the following advantages:
- Accommodation of ground movements as shown in the diagrams below.
- Allowing adjustment while installation.
- Reducing the number of bends required.
- Locked Standard Push-On Pipes:
Locked push-on pipes function similarly to the standard type. However, they include a weld bead near the spigot end (at distance “a” in the diagram). This weld bead enhances compatibility with restrained joints, which are essential for above-ground installations.
For a complete restrained joint system, SADIP provides the necessary accessories, including: Glands / Rings / Bolts / Nuts.
joints:
SADIP offers flanged pipes and fittings in various specifications, including PN10, PN16, PN25, PN40, BS10, and ANSI, based on customer requirements. The length of flanged pipes can be customized according to agreements between the customer and the plant, with options for puddle flanges if needed. Additionally, flanged fittings are manufactured according to the dimensions specified in the SADIP catalog.
- Mechanical & Express Joints:
Collars supplied with mechanical or express joint depending on the customer requirements and in line with the dimensions and details given in SADIP catalogue.
Advantages of Joints:
| Features | Push-in joints | Mechanical joints | Self-anchored joints | Flanged joints |
| End play | YES | YES | YES | NO |
| Angular deflection | YES | YES | YES | NO |
| Resistant to axial forces | NO | NO | YES | YES |
| Ease of assembly | VERY EASY | SIMPLE | SIMPLE | SIMPLE |
| Jointing force required | YES | NO | YES | NO |
