Why PT&P Spring Supports

PT&P is setup to offer our customers the absolute best value in Spring Supports.  The following are key factors that differentiate PT&P Spring Supports:

  • Global Leadership – PT&P has been providing spring supports for over 40 years and has millions of Spring Supports currently in service. We are the standard used by many EPCs and Operating Plants globally.
  • Superior Engineering and Support – PT&P is the only major Engineered Pipe Support provider that started as a Pipe Stress Engineering company. This one of the reasons why we are the only major global provider of both engineered pipe supports and expansion joints.  When you order from PT&P, you not only get our product, but you also get service from one of the world’s leading Pipe Stress Engineering firms.  We can assist in product selection, installation advice, and maintenance advice.  We conduct 100+ individualized Technical Training sessions each year for EPCs and Operating Plants.
  • Superior Manufacturing – PT&P manufactures to a higher standard than other Engineered Pipe Support providers. One of the reasons we are the only major manufacturer of Expansion Joints and Pipe Supports is that the skill level required to manufacture Expansion Joints is distinctly higher than Pipe Supports.  For example, we TIG weld thin gauge Hastelloy and other superalloys every day in our Expansion Joint production. Beyond the superior skills we keep on staff, PT&P has a unique ability to service short lead-time orders.  Some of these are in as little as 12 hours.  Our unique manufacturing approach is explained on this link.
  • Superior Quality – we have seen many Spring Supports in the field that have been highly “cost-engineered’. The easiest way to look for this is to check the support for the use of thin gauge material (you can just tap on it).  This is often accompanied by a painted finish which must be used because galvanizing, while far superior (paint vs galvanized) for most applications, would warp thin gauge material.PT&P has not gone through this cycle of cost-engineering.  If you check PT&P spring support, you will quickly see we use thicker gauge material with a standard galvanized finish that is designed to last for the long term and survive in the most difficult environments.
  • Unparalleled Customization Options – because PT&P has set up it’s manufacturing to easily accommodate customization and has advanced manufacturing skills that other spring support manufacturers lack, we can offer the broadest range of options. These include

Benefits of G10 Micarta® for Insulation

Download PDF

Pipe Clamps

G10 Micarta® can be very cost-effective insulation as compared to Polyurethane foam (PUF), especially for medium and large shoes. It offers tremendous benefits at various stages of a project, including but not limited to:

  • Procurement
  • Installation
  • Handling, transportation, and storage
  • Plant Maintenance
Cryogenic Pipe Supports with Micarta® Insulation for an LNG Plant

Major Advantage of G10 Micarta® Supports for Procurement

G10 Micarta® supports involve fewer steps to manufacture, allowing for a quicker fabrication turnaround. It takes 2-3 weeks less on average than PUF supports for delivery. This enables the ability to catch up on deadlines and reduce downtime.

  • G10 Micarta® shoes cost less than PUF shoes of the same size, meaning Low Capital Expenses:

Advantages of G10 Micarta® Supports During Construction/Installation

G10 shoes can be sent to the pipe fabricator and can weld directly to the pipe spool, meaning there is minimal installation in the field. It takes 3-5 hours to install a PUF shoe in-field, depending on the size. G10 Micarta® shoes save that FIELD installation time.

Micarta® Block Assemblies for Placement Beneath a Saddle Support of a Vessel

Shop welding of G10 Micarta® shoes is much cheaper. As G10 shoes are weld to pipe spool at the fabricator’s shop, they can be inspected and tested in the shop; no inspection and testing in the field. More cost savings as inspection and testing is done at cheaper rates at pipe spool fabricator facilities rather than in the field.

As G10 Micarta® shoes are handled along with the pipe spools, there are fewer chances of missing supports in the field. Less OS&Ds to worry about for both the client and supplier.

Major Advantage of G10 Micarta® Supports while Handling, Transportation & Storage

G10 Micarta® supports are less fragile than PUF, making the handling, transportation, and storage of G10 to be trouble-free. No special packaging required, saving the time & the cost of special crating. Stronger G10 supports reduce the chances of accidental damage, thereby the need to re-fabricate the support.

Cryogenic Pipe Supports with Micarta® G10 Insulation, and Axial Stops for an LNG Facility

G10 Micarta® supports have insignificant water/moisture absorption rate, this means:

  • No structural deterioration in adverse weather, especially in the wake of heavy rain and storms. PUF deteriorates in wet weather or humid climates
  • Better life of the support
  • Less maintenance and more saving

Variable Spring Supports Designed for a Highly Corrosive Environment in Peru

Variable Spring Supports Designed for a Highly Corrosive Environment in Peru

Type: Variable Spring Supports w/ PTFE Slide Plates
Size: PTP-4 | 9.5″ – 11.5″ Height
Design: 1/8″ Upward & 3/16″ Downward Travel
Material: HDG Carbon Steel | Gloss Aliphatic Polyurethane Topcoat | PTFE, 25% Glass Filled Slide Plates

Piping Technology & Products, Inc. recently designed and fabricated F-type variable spring supports for a plant in Peru. The variables are fabricated from carbon steel, hot-dipped galvanized and a gloss aliphatic polyurethane topcoat was applied for corrosion protection. PTFE, 25% glass filled, slide plates are bonded to the top of the load flange to reduce the friction caused by lateral movement. The variables range from 9.5″ to 11.5″ in height and are designed for a travel range of 1/8″ upward to 3/16″ downward. To ensure quality, standard load testing was performed prior to shipping.
