Manlid Assemblies

TankPart Limited now stocks manways in the UK! 


Our latest designs of manlid assemblies are manufactured to the latest standards and exceed the industry expectations in terms of quality and performance. Not only are the lids manufactured to ASME Viii Div 1, but also certified to RID, ADR, EN14025, CFR 49, IMDG and certified by Bureau Veritas. 

Each and every manlid, or manway assembly, is manufactured to the highest standards and fully inspected throughout the manufacturing process to ensure our products exceed your expectations in service. 

We are also able to work with you and your project teams to manufacture bespoke manlids, so if you want a flange or socket in the lid or neck to accommodate a fitting, not a problem! We also manufacture flat bolted flanged lids too. 

The standard sizes available are 170mm, 300mm, 460mm, 500mm and 600mm. We have various neckring designs including straight, compensated and profiled. 

Our manlids are generally designed and manufactured in stainless steel to transport codes HOWEVER, they can also be used for static plant applications and are supplied, as standard, with full documentation meeting the requirements of PED too.
