LALLY MIN-YIELD™ Specification


New mill secondary tubular products are recognized as an industry standard for use in applications such as bollards, casing, columns, culverts, fencing, piling, rollers, sign poles, supports, water well, etc.  Experienced users of these products prefer secondary material for these applications due to stock availability, installation and in-service performance, longstanding use, and lower price.

LALLY MIN-YIELD™ Specification

June 2014

  1. This specification covers nominal (average) wall tubular products in sizes up to 26” O.D. made by the Electric Resistance Weld (E.R.W.) or Seamless process.  The seams of the welded material are longitudinal.
  2. This standard is intended for general structural tubular applications for bollards, casing, columns, culverts, fencing, piling, rollers, sign poles, supports, water well, etc.
  3. This standard does not purport to address all of the safety problems, if any, associated with its use.  It is the responsibility of the user of this standard to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.
  4. The tubular products were made by major domestic mills using one or more of the following processes:  open-hearth, basic-oxygen, or electric-furnace.
  5. These tubular products were generally produced to Standard Pipe, Line Pipe, or Oil Country Tubular Goods specifications, and then classified as reject or mill seconds.
  6. We do not know the reasons for these tubular products being rejected by the mills.  These tubular products can be rejected by the mills for many reasons such as O.D. dimensions, I.D. or drift dimensions, wall thickness dimensions, chemistry, surface condition, tensile and yield, threads, non-technical issues like order overage, etc.  Normally, it will not meet the intended ASTM, API, or customer specification that it was produced to.  When these tubular products do not meet the intended specification, the mill classifies the material as reject, and it is shipped to Lally Pipe & Tube facilities.
  7. We will check the O.D., I.D., wall thickness, straightness, and general surface condition.  We will further check for any applicable customer requirements.
  8. We will verify the physical requirements via one or more Independent Test Report(s) taken from randomly selected samples of Lally Pipe & Tube inventory lot(s).  This testing will include chemical analysis per ASTM-E415 and mechanical testing per ASTM-A370 for yield, tensile and elongation.

General Definition of New Secondary, Structural & Limited Service Steel Pipe

The use of New Secondary, Structural and Limited Service steel pipe for bollards, casing (horizontal and vertical), columns, fabrication, original equipment manufacturers, piling, service centers, resellers, and water well has been recognized as the industry standard for many years as a sensible money-saving solution.

Periodically, we are asked to provide a general definition of New Secondary, Structural and Limited Service steel pipe.  Here is a general definition taken from the National Association of Steel Pipe Distributors 1996 edition of the Tubular Products Manual:

Producing mills, at the time of manufacturing, reject pipe which cannot be classified as a prime product because of some physical or chemical defect.  This material is sold by the mills to steel pipe distributors, steel products [sic], fabricators, and consumers.

Mill rejects are sold on an as is basis and carry no warranty of any kind either expressed or implied.

Reject pipe is available in CW, ERW, DSAW and Seamless, in all sizes, weights, and classes of material.  Although reject pipe carries no warranty whatsoever, it can have application for structural purpose.  [Emphasis added.]  Some typical examples where reject pipe has been used are:  handrails, columns, posts, piling, sand wash, casing, culverts, fence, caissons, sign poles, bumpers, bracing, parking meter posts, towers, supports, rollers, etc.  Reject pipe is normally priced substantially under prime pipe and can affect large savings in the right application.  [Emphasis added.]  However, the buyer should be kept continually aware that this material carries no warranty of any kind, either expressed or implied from the producing mill or the pipe distributor.

Reject pipe is also known in the trades as structural grade pipe and/or Limited Service Pipe.  In certain instances, encompasses pipe which is manufactured to a specific ASTM or API specification, but because of some chemical or physical flaw does not meet the rigid requirements [emphasis added] of the intended specification.  This pipe could be subjected to lesser hydrostatic test pressures than the original specifications required and this product could be classified as Limited Service or Minimum Test Pipe.  Limited Service or Minimum Test Pipe of this description can have application in low pressure situations such as water well or surface casing.  Generally, when Limited Service Pipe has been subjected to a minimum test it will be clearly marked on the product.

Since 1933, Lally Pipe & Tube has provided New Secondary, Structural and Limited Service customized steel pipe solutions to thousands of projects large and small.  So whether you need material in days or weeks, we can help you with Game-Changer customized solutions for your situation.

Why New Secondary, Structural & Limited Service Steel Pipe?

On a beautiful late spring afternoon, twenty-five years ago, two young men graduated from the same college.  These two men were very much alike.  Both had been better than average students, both were personable and both — as young college graduates are — were filled with ambitious dreams for their future.

Recently, these men returned to their college for their 20th reunion.

They were still very much alike.  Both were happily married.  Both had three children. And both, it turned out had gone to work for the same Midwestern pile driving contractor after graduation, and were still there.

But there was a difference.  One of the men was a manager of a small department of that company.  The other was its president.

What Made The Difference

Have you ever wondered what makes this kind of difference in people’s lives?  It isn’t always a native intelligence, talent or dedication.  It isn’t that one person wants success and the other doesn’t.

The difference lies in what each person knows, and how he or she makes use of that knowledge.

And that is why we are writing to tell you and others like you about Lally Pipe & Tube.  For that is the whole purpose of Lally Pipe & Tube:  To give its customers knowledge – knowledge of Game-Changer customized steel pipe solutions they can use in business.

A Company Unlike Any Other

You see, Lally Pipe & Tube is a unique company.  It’s America’s largest single source of New Secondary, Structural and Limited Service steel pipe products and customized solutions.  Each business day, we work to help companies with money-saving steel pipe solutions.

Each business day, Lally Pipe & Tube receives new steel pipe inventory, sales representatives sell, warehouse workers labor, and lots of orders are shipped to customers all across the country.  And all these customers easily save money on the steel pipe they need for projects large and small.

Knowledge Is Power

Right now, we’re working with a prospect that needs steel pipe piling for a fast breaking commercial project.  The prospect is telling us they need to start the project as soon as possible, but they have a huge problem.  Seems they bid the project several months ago using another supplier that gave them a price for prime, fancy material from a mill rolling.  And since that time, the mill has raised the price and the prospect is distraught.

That’s right up our alley, so we’re offering them spliced to length New Secondary steel pipe with Independent Test Reports for delivery in about 2-3 weeks.  And it turns out our price is 20% cheaper than the prospect’s original bid estimate.

Looks like their problem is solved because the prospect remembered Lally Pipe & Tube, called with an inquiry, and was open to money-saving options.

Add Us To Your Bid List

Add us to your bid list for steel pipe.  We are the single best way for you to add extra profit to your bottom line with no extra work or investment on your part.

Now when you need prime, fancy steel pipe with Mill Test Reports, our company is not the place for you.  But when you can use New Secondary, Structural and Limited Service steel pipe, and can trade Mill Test Reports for Independent Test Reports, you’ll like us just fine.

So What Happened

Now about those two college classmates mentioned at the beginning:  They were graduated from college together and together got started in the business world.  So what made their lives in business different?

Knowledge.  Useful knowledge.  And its application.

A Valuable Resource

We cannot promise you success will be instantly yours if you start buying from Lally Pipe & Tube.  But we can guarantee that you will find Lally Pipe & Tube always useful.
