Site Survey

For the site survey we will audit your supports on any of the lines that you point out to us and verify their condition. We will examine the spring supports — we will check the housings, coils, and all related hardware. We will mark each support as OK, Replace, or Adjust – in the case of variable and constant spring supports. Upon completion of the survey we will provide a report listing all of the supports and our recommendations. We will also provide you with a quotation for the supports that we recommend that you replace.

Stress Analysis and Design

We can provide pipe stress analysis and pipe support design as well using current modeling software.

Pipe Support Testing

We can come onto site and test your constant supports and variable supports.

Production

PT&P is a complete and fully qualified manufacturer of pipe supports and hangers.  We have over 25 years of experience and are certain that we can meet any deadline that you need for the supports. Our quotation will include material and manufacturing costs, as well as the time frame for the supply of the recommended supports.

Installation

PT&P has over 10 years of experience in the installation of pipe supports and over 35 years of manufacturing experience. Our crews work safely and can install any of our supports. We have welders, technicians, engineers, and supervisors.

Oversight

PT&P will provide qualified site management personnel to oversee the installation of the supports. The individual(s) will provide technical assistance to the contractor, as well as Client personnel.

Inspection Checklist — Hanger / Support Assemblies

Hanger

Base Spring

In the inspection of spring hangers, we will:

  • search for signs of visual cracks, fractures, or corrosion of the spring casing and the following:
    (1)  beam attachment
    (2)  pin
    (3)  spring hanger attachment
    (4)  pipe clamp attachment
    (5)  weldless eye nut/clevis
    (6)  threaded rod
    (7)  turnbuckle
    (8)  nuts
    (9)  spring coil
    (10) position
  • check the turnbuckle (7) if present, lock nuts (8), and all other threaded items to ensure they are secured and fastened with full thread engagement
  • compare the position of the coil (10) with the hot/cold load indicator and operating range of the spring
  • check the mobility of the load column (11)

 

Inspection Checklist — Expansion Joints

Expansion Joint Bellows
  • check for signs of leakage or a loss of pressure
  • inspect for any distortion or yielding of anchors, hardware, bellows, and piping connection points
  • observe for any unanticipated movement of piping due to pressure
  • inspect for evidence of instability (squirm), distortion or damage in the bellows convolutions
  • check the expansion joint, the guides, and other moveable parts of the system for evidence of binding
  • check for misalignment of the expansion joint unit
  • check for vibration damage

Case studies: PT&P Emergency Service 24×7 Hotline

Case Study #1

An Alaskan petroleum firm called upon the PT&P Field Service Team on a Friday evening to aid them in an immediate replacement of a defective 48″ dia. expansion joint.  The expansion joint was damaged during the plant startup when a G417 pump suddenly failed.  A replacement expansion joint was designed, manufactured, and shipped the next day.  It was installed at the customer’s location within 2 days of receiving the call.
