Closure Flange Support Hinges for Supporting Medium to Heavy Duty Blind Flanges
January 28, 2019
Permanent And Removable Hinges For Supporting A Medium To Heavy Duty Blind Flange
Closure Flange Support Hinges for Supporting Medium to Heavy Duty Blind Flanges

Presently, blind flanges are used to provide an airtight cover to various piping systems that include pipelines in the oil industry, heat exchangers, ships, tanks, etc.

Routine maintenance requires the heavy duty blind flange to be removed for cleaning and repairs. However, for these types of flanges, it is quite difficult to disassemble, clean and repair. It typically requires employing a forklift, crane, or other lifting devices. This can require excessive man-hours, and the alignment of the flanges can remain unpredictable.

PT&P introduced a closure flange hinge with specially designed self‐locking bolts and two self-lubricated hinge studs to support the blind flange when all the fastening bolts are removed for maintenance or replacement. The blind flange can be opened like a “door” with little effort. Our product opens up to 180 degrees, providing full accessibility to work on the pipeline, heat exchanger, or other equipment.

To solve the issues, PT&P invented two versions of closure flange hinges for blind flanges: temporary / removable hinge and permanent / fixed hinge

Portable Hinges Project Amount   Portable Hinge Close Up

PT&P recently designed 159 permanent and removable hinges for up to 72″ diameters, We can accommodate for larger sizes upon request.

Personnel Protection Shields, Designed And Fabricated By Pt&Amp;P For A Local Refinery

View PDF on Personnel Protection Shields

Type: Personnel Protection Shields
Size: 11″ Dia. | Up to 48″ Lengths
Material: Carbon Steel | 2-Coat Paint System
Design: Operating Temps. Require Safeguarding Personnel

PT&P custom designed, fabricated and provided installation oversight for sixty-five personnel protection shields for a refinery in Texas. The personnel protection shields are used when insulating the line is not necessary, but operating temperatures require safeguarding personnel from coming into contact with the pipe. These shields are fabricated from carbon steel with a two-coat paint system. They are 11” diameter, and range in lengths up to 48”.

300+ Cryogenic Insulated Pipe Supports (Cold Shoes) for LNG Service
November 26, 2018

300+ Cryogenic Insulated Pipe Supports Designed For An Lng Pipeline

Type: Cryogenic Insulated Supports
Size: Range: 6″ to 24″ Dia. Pipe
Material: Carbon Steel | Hot-dipped Galvanized | PUF
Design: 15,000 – 30,000 lb. Load | -112 F | +/- 2″ Movement

Over 300 pre-insulated pipe supports were custom fabricated for a cryogenic pipeline at an LNG facility in Louisiana. High density polyurethane foam was used for insulation, with thicknesses ranging from 2” to 4”. The cold shoes are for pipe diameters ranging from 6” to 24” and are fabricated from carbon steel with a hot-dipped galvanized finish. They are designed for temperatures down to -112°F, movements of +/-2” and operating loads ranging from 15,000 to 30,000 lb. Standard quality control tests were performed prior to shipment.

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.

Pt&Amp;P Custom Designed Big Ton Spring Supports For An Oil Refinery In Australia

Type: Big Ton Spring Supports
Material: Carbon Steel w/ HDG Finish
Design: 13,457 lb. Load | 0.35" Vertical
Testing: Load and Travel Tests

These big ton springs are used in supporting large heavy units such as compressors, vessels and pumps in power and petrochemical plants. The housing and frame are fabricated from carbon steel and hot-dipped galvanized, and the spring coils are dipped in a neoprene coating. The units are 48” x 40” x 20”. The big ton spring support is designed to allow limited movement of 0.35″ upwards and an operating load of 13,457 lb. This design saved the customer from having to entirely redesign the piping system, which saved them thousands of dollars. Load and travel tests were performed prior to shipping to an oil refinery in Australia.
