Home improvement tool for pipework alignment, designed to make bolting two-hole ASME flanges quicker and more reliable. Confidence on-site comes from precise thread engagement and a durable anodised finish. Is the HouYeen Flange Alignment Pin the right fit for routine flange maintenance tasks?
⚡ At a Glance
- • Alignment Precision: Accurate centring for two-hole flanges, minimises misalignment during bolt-up
- • Best for: Plumbers, pipefitters and maintenance teams working with ASME 150LB flanges from 1/2" to 14"
- • Not ideal for: Applications using tapered, specialised or non-ASME flange types outside the 150LB standard
Anodised aluminium alignment pins with 1/2" thread for ASME 150LB two-hole flanges. Supplied as a pack of two for matched alignment tasks.
Faster flange assembly - thanks to 1/2" thread size
A 1/2" machine thread engages standard flange bolt holes to hold flange faces in correct relation while bolts are fitted. Smooth thread geometry permits easy insertion and removal without cross-threading.
Shorter installation times and fewer hands needed during bolt-up, which helps single-person maintenance. Repetitive jobs finish more quickly, reducing downtime.
Reduced wear and corrosion risk - with anodised black oxide aluminium
Anodised aluminium develops a hard oxide layer that resists surface wear and mild corrosion, while keeping overall weight low. The finish also reduces the chance of metal transfer to flange faces during alignment.
Longer-lasting pins that are kinder to flange surfaces, lowering the risk of damage during alignment. Easier to clean and maintain between uses.
Broad compatibility across flange sizes - with suitability for 1/2"-14" ASME 150LB flanges
Thread size and pin geometry match common hole patterns found on ASME 150LB two-hole flanges across a wide diameter range. Design focuses on straightforward use with typical pipeline bolt arrangements.
A single pair covers many common small to mid-size flange maintenance tasks, reducing the need to carry multiple pin sizes. Useful for mobile engineers and site teams.
