Introduction

Governed by ASME, Board ofPressure Technology Codes &Standards

The Bible for FRP Tanks!

RTP-1 is a national and internationalstandard.

The most comprehensive standard

for FRP storage tanks.

Specified around the world.

Background

First Published by ASME in 1989 Updated every 2 year, 2011

Currently 11 Certified for RTP-1

Maintained by an ASME Committeeof industry related members

Design Conditions from FullVacuum to +15 PSI

ASME RTP-1

Perception: Provides Good Quality,but Its Expensive!?

6

Reality:

Not Much More!

~0-10%


7/32

ASME RTP-1

Perception: Its only a designguideline, similar to ASTM D3299

Reality:

Its much more

than that!

Reality: I want it designed in

accordance with RTP-1.

What does

that mean? What are the

expectations?

15


16/32

Reality: I want it designed in


What does that mean?

What are the expectations?

16

I expect full compliance with

RTP-1 Part 3, Design.


17/32

I want it designed in


What are the realities? Questions!

17

Does the manufacturer have a goodunderstanding of RTP-1?

Will a Professional Engineer performthe calculations?

How will the assumptions for thematerial properties be verified?


18/32

I want it designed in


What are the realities?

18

No worries about anything else?


19/32

Reality: I want it in accordance

with RTP-1, but a stamp is not

required.

What does that mean? What are the expectations?

20/32

I want it in accordance with RTP-1,

but a stamp is not required.


What are the expectations?

20

I expect full compliance with RTP-1 and

RTP-1 quality, but can be built by amanufacturer that is not certified byASME.


21/32

Reality: I want it in accordance

with RTP-1, but a stamp is not

required.


21


22/32

I want it in accordance with RTP-

1, but a stamp is not required.

What are the realities?

22

Proven Material Properties? Qualified Fabrication Methods?

Quality Control?

Certified Laminators?

What am I getting????


23/32


24/32

I think we can see there is

significant value in an ASME

RTP-1 Certified Tank.

Safety is always a concern. Reliable production is

imperative.

Makes sense from a riskmanagement standpoint.

25/32

If I dont ask for an ASME RTP-1

Certified Tank, what can I do tomeet expectations?

25


26/32

If I dont ask for an ASME RTP-1

Certified Tank, what can I do tomeet expectations?

The Owner or Owners Engineer hasto take responsibility and a moreactive role in the procurement andquality assurance process.

26


27/32

Additional Responsibilities of the

Owner or Owners Engineer

First:

Need a Comprehensive andDescriptive Specification

Prequalify Capable Vendors,maybe a shop visit and audit.

27


28/32


Owner or Owners EngineerDesign Concerns:

Design review of Calculations for

Good FRP Engineering Practices

Review of Fabrication Drawings forCompliance with RTP-1 and calcs

Require and confirm MaterialTesting to validate designassumptions

28


29/32


Owner or Owners EngineerFabrication and Quality Control:

The Owners Specification needsto provide for some checks andbalances

Fabrication Kick-off Meeting

In-process inspections Review of fabrication and QC

Documentation

ASME RTP-1 Tanks?

Certified Stamp:Its a decision based on prioritiesand needs, but it should be an

informed one. Dont Assume!
