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
- Material
- Dimensions
- Travel
- Coating
- Delivery Timeframe

| Material: | Carbon Steel with HDG finish | Casi & High Density Inserts |
| Design: | 1200°F | 15,000 lb. Vertical | 6,245 lb. Axial |
These pre-insulated high-temperature pipe supports were designed and fabricated for a 10” diameter high-temperature pipeline at a power plant in Arizona. The supports are fabricated from carbon steel with HDG finish and include casi & high-density inserts. They are designed to guide pipes that may reach up to 1200°F, high loads of up to 15,000 lb. vertical and 6,245 lb. axial. There were twenty-nine total “hot shoes” ranging in different designs. The “grooves” in the insulation are for steam tracing. Steam tracing is heat tracing performed by circulating steam around process pipes to heat them. The shoe assemblies are comprised of the four guides on the shoe and adjustable stops. They are designed to account for lateral, vertical, and axial movement. Dimensions for the supports pictured are 10” NPS x 6” thick insulation x 12” long base. Standard tests and Q.C. inspections were performed before shipping.

Unparalleled Customization from Unmatched Manufacturing Capabilities
PT&P has developed a unique approach to its manufacturing operation that produces the broadest set of customization options with minimal impact to delivery timeframes. Most producers operate as smaller scale steel fabricators or highly standardized mass production organizations. PT&P is the only organization that is set up for both scales with over 500 production employees, customization capabilities, and artisan manufacturing skills. For example, PT&P is the only Major Global Supplier of both Expansion Joints and Engineered Pipe Supports. This unmatched manufacturing technique was achieved through proprietary systems, a highly engineered approach to manufacturing, and incorporating 10+ Industrial Engineers in the production operation.

Benefits of G10 Micarta® for Insulation
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
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.
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.
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
