Bolted RTP (rolled, tapered panel) design
– Panels are horizontal 5' ht. x 10' length

– Utilizes flat panel technology for precision alignment and exact fit.

RTP tank construction is the premier bolted tank design available in today's market for dry bulk and liquid storage applications . . . worldwide.

The RTP design combines the best of both field-weld and bolted tank construction into the highest quality bolted design ever developed in the storage industry.

Typically, RTP tanks are jacked from grade level utilizing a synchronized hydraulic screw jacking process, which is rated as the safest tank construction available in the industry. RTP tanks can also be scaffold built.

Product Review:
– No chime equates to no leaks
– No internal ledges
– Heavy tank designs for industrial service (up to ½" plate)
– Fusion powder coating wrap-around on steel
– Field construction – #1 rated process, jacked from grade level

Product Rating Dry Bulk: Excellent
Product Rating Liquid: Excellent

API 12B flanged panel tank
– Panels are vertical 8' ht. x 5' wide

– Utilizes an exterior horizontal flange connection called a chime.

The API 12B flanged panel tank is an outdated bolted tank design that originated in the oil patch territories in the early 1900's. The big problem with this design is the exterior horizontal flange (chime) connection, which has a history of continuous leaks. Additionally, the exterior flange connection creates a ledge that holds material, moisture and debris, which removes the paint quickly. Typically, you will witness this product in the field with rusty horizontal connections from top to bottom of tank.

Product Review:
– Archaic / outdated design
– Chime lap connection has a history of continuous leaking
– Light tank design designs only (up to ¼" plate)
– Horizontal flange connection creates 2" exterior ledge which holds moisture, material, debris, and rusts quickly
– Internal ledge holds material
– Outdated construction process elevates field installation crews in the air on scaffold planks

Product Rating Dry Bulk: Poor to Avg.
Product Rating Liquids: Poor
Product Rating Crude Oil: Average

Vertical notched panel tank
– Panels are vertical 8' ht. x 5' wide

– A vertical panel design developed to remove the problematic (chime) flange connection on the API 12B tank.

This product is a poorly conceived storage tank design. The use of this product has been limited and the product review is quite poor. When scaffold built, the tall & narrow panels tend to fold over in very low wind conditions. The panels have no arc rigidity. To offest this, construction crews have to tie the scaffold boards and brackets together with "C" clamps, simulating a make-shift girder for stability.

This type of construction is unsafe and will not meet minimum field safety requirements.

Product Review:
– Vertical notched panels – poor design and unsafe to install
– Designed to replace the API 12B tank
– Outdated construction process elevates field installation crews in the air on scaffold planks
– Aesthetic review – poor

Product Rating: Poor – all storage applications
