EXTERNALLY STIFFENED & SPECIAL TANKS
If rectangular tanks cannot be manufactured with internal cross stays, external channels or angles are welded to achieve the same performance. Non standard tanks are specially designed by Hartwell, with prices on application.

SITE WELDED TANKS
When access to site is difficult, i.e. basements, rooftops, tanks are prepared in small sections before being welded, tested and painted in situ. Supply and erection costs, will be confirmed by Hartwell following site visit although it is often possible to give close budget prices without site inspection.

THIRD PARTY INSPECTION By Client or Integ

PED (Pressure Equipment Directive) If for European use, and if the working pressure is above 0.5barg, then PED regulations apply.

THIRD PARTY DESIGN APPRAISAL, SURVEILLANCE & INSPECTION

All pressure vessels manufactured to PD5500 and ASME Vlll codes must be inspected by competent Independent Insurance Authority. Order for this work is normally placed by Buyer, but Hartwell can arrange Inspection for code compliance

DESIGN CODE

The listed vessels are designed to PD5500 Category 2, which for most applications provides the most economic vessel scantlings. For a given design, Category 1 vessels are of exactly the same thickness material but the welds are subject to 100% NDT.

Category 3 vessels are only subject to visual inspection of welds and whilst some small vessels can be economically viable, this category generally results in thicker vessels due to the restricted design stress. Vessels designed to ASME Vlll can vary in thickness (+/-) when compared to the equivalent PD5500 vessel.

Hartwell vessel engineers with many years of design experience and aided by the latest computer software can guide clients to achieve the optimum design code/category for a particular application.

Below Ground Single Skin Stainless Steel Typical Arrangement Tank

UNDERGROUND TANKS – SINGLE ‘SKIN’ CONSTRUCTION

A COMPLEMENTING RANGE OF UNDERGROUND TANKS (2 – 90 CUBIC METRES) IS AVAILABLE WHERE EXTRA INTEGRITY AND SPILL PROTECTION WITH INBUILT LEAK DETECTION IS ESSENTIAL.
