LK-B2 / Sanitary Square Manhole
SS316L Square Manway for Hygienic Tank Access
LikeMetals helps tank-equipment buyers review a sanitary square manway manufacturer option and compare details used by sanitary square manhole manufacturers, including material grade, opening size, gasket choice, surface finish, and handle format.
Use this page to prepare square manway requirements before sending drawings, tank access needs, or material questions to LikeMetals.
Square Access Fit
Start With the Opening, Cover, and Handle
A sanitary square manway is chosen around tank access geometry first. LK-B2 brings the practical details buyers need to check before discussing fabrication or replacement work.
Opening Footprint
Size options include 430 x 330, 530 x 410, and 530 x 430, so the first decision is the opening footprint and clearance around the tank wall.
Outward Cover
The product is listed as an outward opening manhole cover, a useful boundary when planning access space and service routines.
Handle Format
Spanner type and hand wheel handle options should be checked against the operator's routine, available space, and cleaning practice.
Keep the product view beside the specification table while checking dimensions, material grade, handle format, and sealing details.

Surface And Seal Boundary
Turn Finish Details Into RFQ Inputs
Square manway inquiries become clearer when buyers separate wetted-surface expectations, visible finish, gasket material, and steel grade before asking for price or drawings.
Confirm whether the listed Ra 0.05-0.5 um range matches the process area where the cover will be installed.
Choose matte, mirror-polished, or sand-blasting finish for cleaning visibility, surrounding equipment, and appearance needs.
Ask LikeMetals to match silicone, EPDM, NBR, or FPM to the medium, temperature expectation, and cleaning routine.
Use SS304 and SS316L as the material discussion points, then confirm the final grade against the tank environment.
