National Association of Steel Pipe Distributors

2010 Annual Convention

February 26, 2010

loading pipe on rail
Loading Pipe on Rail
  • Safety
  • Damage
  • Innovations
  • Problems
  • Solutions
slide3

Center Beam Cars – Alternative Loads

  • Too Many Centerbeams, Building Industry down
  • How to better utilize the asset
slide4

Challenges for Alternative

Products

  • Specially designed cars for building products
  • Load limit considerations
  • Damage to equipment and future loadings
  • Load/unload from two sides (tarps)
  • Centerbeam and height of same cables
slide6

TESTING

Railway Assn of Canada

Impact tested – structural steel, small diameter pipe, rebarField Testing – Limited amount account limited shipper

interest

BNSF/AAR

VTU test procedures using pipe on Centerbeams

slide10

Based on AAR Testing Procedures,

AAR Open Top Loading Rules Committee:

- Approved Rigid Pipe of 12”, 16” and 24”

- Did not Approve Smaller diameter “flexible” pipe

- Got the opportunity to see Cord Strap perform

under dynamic testing

More to come.

pipe loads in open tops using non metallic strapping
Pipe Loads in Open TopsUsing Non-Metallic Strapping
  • Ductile Pipe with Cord Strap
  • Coated Pipe under test
slide16

So How do we solve this?

Answer: John Blackman

“Non-metallic strapping -

Strength of steel with some

Elasticity.”

slide17

Innovative J hook

  • Polyester Strapping
  • Doesn’t Crack/Break as easily
  • Cost competitive
  • Virtually eliminated Service
  • Interruptions
  • Safer to Use
cordstrap performance
CordStrap Performance
  • Initially tested on over 100 loads – no strap breakage
  • ACIPCO using since January 2009, less than 5 loads with broken straps
  • ACIPCO Setout Incidence 1st qtr 2009 – 2%
  • Steel band ductile pipe shippers – 12.3%
slide24

Older Figures (pre-1960)

  • Allows 12-inches of end
  • clearance
  • Standard Draft Gear Equipment
  • Setout incidence up to 16%
  • Impact Test to determine amount
  • of load movement
slide26

Impact Test Conclusions

  • Pipe moves more than 12 inches
  • Repeated impacts, even at low speed
  • will produce shift over end of cars
  • Existing Figures need to be changed
  • in-line with “reality”
impact test conclusions
Impact Test Conclusions
  • A timeline has been established to

incorporate changes to Figures October 2010 is the target date

  • AAR TAG is working on the problem
