Slip-on Flanges

Overview

Slip-on flanges locate over the pipe end and are secured by fillet welds inside and out. They ease alignment and reduce fabrication cost, which makes them a practical choice for moderate-pressure process, water and general industrial pipework. FLOWTEC (UK) supplies slip-on flanges configured to order scope, with the final specification confirmed at quotation stage.

At a glance

Slip-on flanges for moderate-pressure process, water and general industrial pipework, located over the pipe end and secured by fillet welds. Specification confirmed against your project requirements.

• Slides over the pipe end for easier alignment and lower fabrication cost
• Suited to moderate-pressure service rather than fatigue-critical duty
• Referenced to ASME and EN design bases; raised-face facing
• Materials and documentation confirmed at quotation stage

Typical applications

• Moderate-pressure process and utility lines
• Water and building-services pipework
• General industrial pipework

Typical use & selection context

Well suited to lower- and moderate-pressure lines where installation speed and alignment tolerance matter more than the fatigue performance of a weld-neck joint. Selection considers design pressure and temperature, pipe outside diameter, facing, and the governing standard, each confirmed against the line specification.

Pressure class

ASME Class 150 - 1500 · EN 1092-1 PN 6 - 40

Size range

½″ - 24″ (DN 15 - 600)

Standards & facing context

Referenced against ASME B16.5 and EN 1092-1 Type 12 / Type 02 equivalents. Indicative envelope: ASME Class 150–1500 or EN PN 6–40, sizes ½″–24″. Raised-face is the usual facing. Standards references are a design basis only, not a statement of certification.
