ABOUT THE 6″ SCH 40

6-inch Schedule 40 Steel Pipe Bollards are the most common go-to pipe used for parking lot bollards. They are an affordable, robust pipe and at around 150 lbs for an 8-footer, they can still be moved around and placed by a worker or two without mechanical help.

GENERAL APPLICATIONS: The 6″ SCH 40 Pipe is commonly used to protect:

  • Pedestrians where ever vehicles are present.
  • Signs where if plowed down, could cause minor or fatal accidents.
  • Signs that would otherwise be bumped, bent and destroyed by vehicles.
  • Utilities such as fire hydrants, gas and propane tanks and electrical service boxes.
  • Service doors that enter/exit in driving path.
  • Dock door corners, garage service bay door corners and corners of buildings that are often grazed or smacked.
  • Building entrances from errant vehicles and ram-raids. See Bollard Barriers for Store Front Protection.

AS A BARRICADE: A deep pier footing (48″) installation of the 6″ SCH 40 Pipe presents itself as a substantial barrier to small and mid-size vehicles. Reinforcing the concrete with rebar, rebar embedding inside concrete filled bollard as well as trench installation of an array of bollards are all ways to fortify a bollard system against vehicle intrusion. For more certainty in the barriers stopping force, it is advised to use an impact-rated bollard system such as the C40, K4 or K12. But it is worth noting that this pipe is used in many crash-rated bollard systems that have added steel reinforcing and other steel parts that work around and within the pipe. See Bollard Barriers for Store Front Protection.

VARIETIES: ASTM A500 Carbon Steel Pipe is the common go-to choice for bollards. Although, it is sometimes sufficient to use a structural grade untested pipe. Of course, we also offer pipe that meets various prescribed ASTM and ASME standards. See “Pipe Varieties” below.

PIPE VARIETIES

This Pipe may be available in the following types and grades:

Electric resistance weld (ERW), seamless (SMLS), and double submerged arc weld (DSAW) in all published schedules and walls, Grades ASTM A-500 GR A & GR B, ASTM A-53 GR B, ASME SA-53 GR B, ASTM A-106 GR B, ASME SA-106 GR B, AP1 5L X-GRADES, ASTM A-252 GR 1, 2, AND 3, ASTM A-139 GR B, and ASTM A-501.

UNTESTED PIPE VARIANT

This pipe may also be available as untested pipe without an ASTM rating. It is then referred to by Diameter and Wall Thickness only; no Schedule #, Standard, XH or XXH etc. Untested pipe can be much cheaper, and is often perfectly fine for bollard applications since the testing is really about pressure testing; how much PSI the pipe can withstand when filled with a pressurized liquid or gas. Bollards are just filled with concrete, so PSI ratings are generally not applicable. Their may be a small or negligable weakness in terms of bollard strength associated with untested pipe.

MORE PIPE SIZES AND THICKNESSES

See bottom of page for all of our pipe sizes and wall thicknesses. We offer 1/8" to 36" Diameters and walls from SCH 5 to SCH 160 XH Extra Heavy and XXH Double Extra Heavy.

A minimum of 6 is required. Please Note: If you are far from the Midwest, we can only consider quoting larger quantities.
Alert: Galvanized does not hold paint worth a darn because it's acts like a non-stick frying pan, so don't choose galvanized if you are hoping to paint pipe. Leave galvanized be, or cover it with a bollard cover, don't paint it!
Structural ASTM A500 Grade A is often typical. Untested and Rejected pipe doesn't necessarily meet fluid pressure tests, but is usually OK for bollard applications that aren't critical.

Unloading at Shipping Destination *
You must have a way to receive delivery. Trucks don't usually come with a fork and pipe has to be forked from the side of truck. Smaller pipe under 150 lbs can be offloaded by hand, but the driver may not be happy about it. Note: "Forks" is short for forklift, Lull, Track Loader with forks, Skid Steer with forks etc.
