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.

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.

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

Micarta Block Assemblies Designed for a Vessel Application in Texas

Type: Insulated Support – Micarta® Block Assembly
Size: 2″ H x 12″ W x 81″ L
Material: Micarta® | PTFE, 25% Glass-filled
Design: -454°F | Visual / Dimensional Tests

PT&P designed Micarta® block assemblies for placement beneath the saddle support of a vessel at an oil refinery in Texas. These insulated supports measure 2” x 12” x 81” and include PTFE, 25% glass-filled material bonded to the top of the Micarta®. Micarta® consists of glass fabric with an epoxy resin, which provides great insulating characteristics and superior physical properties. The blocks are designed to prevent cryogenic temperatures down to -454°F from transferring past the base of the support to the supporting steel or foundation. Visual and dimensional tests were performed prior to shipment.

Cold Shoe Anchors with Micarta Insulation for a LNG Plant

The cold shoes are fabricated from a combination of carbon steel, micarta insulation, and stainless steel. They measure 18″ x 12″ x 10″ and are designed for 7″ of lateral movement with temperatures as low as -162°C. A total of 16 supports were manufactured and PMI tested. This was a rush order completed in just under 12 weeks for a LNG plant.
