1. Introduction:
Industries across Australia—from oil & gas to water treatment—rely heavily on robust and secure piping systems. One of the most recurring challenges faced by engineers and contractors is ensuring leak-proof connections that can handle pressure fluctuations, corrosion, and misalignment. Traditional flange types, while effective, often come with higher installation costs and require precise alignment.
This is where Slip-on Flanges come into the picture—offering a cost-effective, versatile, and reliable solution to everyday piping challenges.
2. Product Introduction:
Slip-on Flanges (also known as SO Flanges) are a type of flange that is slipped over the pipe and then welded both inside and outside to provide strength and prevent leakage. These flanges are often used in lower pressure applications where speed and ease of installation are crucial.
They are widely manufactured and supplied by Slip-on Flanges Manufacturers in Australia, ensuring compatibility with local industrial requirements and global piping standards.
3. Advantages of Slip-on Flanges
Easy Installation: Requires less precision when cutting the pipe.
Cost-Effective: Lower fabrication costs compared to weld neck flanges.
Versatile Fit: Suitable for different pipe sizes and misalignments.
Dual Welded for Strength: Internal and external welds increase structural integrity.
Availability in Multiple Standards: Compatible with ANSI/ASME B16.5, B16.47 Series A & B, EN-1092, DIN, GOST, ISO7005-1, BS4504, and others.
4. Real-Life Applications of Slip-on Flanges
Oil & Gas Pipelines: Ideal for non-critical pipeline connections
Construction & Infrastructure: Used in HVAC and water distribution systems.
Chemical Plants: Suitable for low-pressure, corrosive environments.
Marine Industry: Used in shipbuilding due to ease of installation and maintenance.
Water Treatment Plants: Great for aligning pipework in large treatment facilities.
5. How Slip-on Flanges Solve Problems & Deliver Results
Slip-on Flanges directly address key issues such as:
Misalignment in piping systems
