CPA PIPE SUPPORT DESIGN WORK

PIPE SUPPORT DESIGN

A well-designed pipe support system is vital in ensuring the safe and efficient operation of the plant in which it is installed.

CPA is increasingly undertaking pipe support design work (as well as subsequent supply) for consultants, engineering companies, and contractors for a wide range of pipe support systems.

The early participation of trained pipe support Engineers and Designers has proved to be an invaluable aid in ensuring timely recognition of any potential issues and that the most cost-effective design is employed. This also minimises the risk of costly site modifications in the future.

In the illustrations shown here, CPA has performed design of secondary steelwork and supports which is integrated within the customer’s 3D design software. 2D fabrication drawings including a BOM of support components are also produced. CPA design work can be performed in a variety of 3D software such as E3D, SP3D, Microstation, Autocad and more.

COLD SHOES BEING SUPPLIED TO AN LNG EXPORT TERMINAL IN USA

CPA is supplying 100’s of cryogenic pipe supports (or ‘cold shoes’) to an LNG export terminal in the USA.

The cold shoes will support both horizontal and vertical piping.

On this job, sold shoes supporting horizontal piping are supplied with a single leg/base (1st photo).

Where axial loads are acting on the pipe (as well as the vertical load), the cold shoes incorporate internal ‘center stops’ and external thrust flanges to prevent axial slippage.

The upper and lower ‘center stops’ are welded to the inside center of the steel cradle which then fit into machined slots on the outer PUF shells. This ensures that there is no axial slippage between the steel cradle and the PUF.

At site, external thrust flanges are welded to the pipe at either end of the cold shoe. This ensures that there is no axial slippage between the PUF and the pipe.

Cold shoes supporting vertical piping are supplied with two legs/bases (2nd photo). They also incorporate center stops and thrust flanges to prevent axial slippage.

Each cold shoe is supplied with two layers of PUF, each layer consisting of two 180° shells. Each shell is colour coded depending on its density. For cold shoes supporting horizontal piping, the lower PUF shells are often required to be of a higher density than the upper shells. Higher density results in increased compressive strength which is required to adequately support the vertical load of the pipe from underneath.

The cold shoe is clamped to the pipe using disc springs (3rd photo). This ensures that there is an adequate clamping force after radial contraction of the pipe and insulation. The disc springs are factory-installed in the correct configuration and CPA’s non-removable arrangement means that disc springs cannot be lost or installed incorrectly.

The steel is hot dip galvanized which provides adequate protection against corrosion.

CPA IS ISO 9001, 14001 AND 45001 CERTIFIED

CONSTANT AND VARIABLE SUPPORTS BEING SUPPLIED TO AN LNG RECEIVING TERMINAL IN TAIWAN

In addition to the cryogenic supports supplied to an LNG receiving terminal in Taiwan, CPA has also designed and manufactured variable and constant effort spring supports to be supplied to the same project.
The spring supports are designed to accommodate vertical and horizontal displacements of piping with loads of up to 10,000 kgs. Pipe sizes range from 6” to 36”. The support assemblies reach up to 2.6m in length.
The spring supports are painted in-house as per the client’s specification. In these photos, they are laid out for inspection prior to packing and shipping.

6,000 U-BOLTS SUPPLIED TO AN OFFSHORE GRID CONNECTION SYSTEM IN EUROPE

U-bolts, U-bolts, U-bolts!

CPA is supplying 6,000 insulated U-bolts to an offshore grid connection system in Europe which connects directly to offshore wind turbines.

The insulating/isolating material is a synthetic rubber which strong, resilient, and achieves an extremely high performance in the reduction of noise and vibration in pipework. It also has an outstanding resistance to a wide range of chemicals (including acids, alkalis, fats, oils, greases and solvents). Furthermore, it has advantageous physical properties including tear and abrasion resistance, ozone and weathering.

In these video, the u-bolts are being wrapped and packed in preparation for shipment.

 

ANTI-VIBRATION PADS SUPPLIED TO A REFINERY IN THE MIDDLE EAST

CPA is supplying 100’s of anti-vibration pads to a refinery upgrading project in the Middle East. The upgrading involves installation of a new fluid catalytic cracking unit, vacuum distillation unit and diesel desulfurization unit which will increase production of gasoline and diesel fuel.
Each anti-vibration pad assembly is comprised of a carbon steel base plate, bolts/nuts and an anti-vibration material composed from laminates of synthetic fabric and high temperature polymer based elastomers which can withstand and absorb sever shock loads at elevated temperatures.
Here the anti-vibration pads are laid out for inspection prior to packing and shipping.

CRYOGENIC SUPPORTS FOR AN LNG RECEIVING TERMINAL IN TAIWAN

CPA is supplying over 2,000 cryogenic supports (or ‘cold shoes’) to an LNG receiving terminal in Taiwan. The cold shoes were designed and manufactured to support a wide range of pipe sizes from 1.5” to 48”.

The cold shoes are painted in-house as per the client’s specification.

Here the cold shoes are laid out for inspection prior to packing and shipping.

CRYOGENIC SUPPORTS FOR AN LNG EXPORT TERMINAL IN USA

CPA is supplying 500 cryogenic pipe supports (or ‘cold shoes’) to a natural gas liquefaction and liquefied natural gas (LNG) export terminal being developed in the USA. The project will have a production capacity of 20 million metric tons per annum (Mtpa).

The cold shoes will support pipe sizes ranging from 4” to 36”. The cold shoes incorporate between 1 and 3 layers of high density polyurethane foam (HD PUF) which acts as an effective cryogenic insulating and load bearing medium. The HD PUF layers are stepped in order to prevent cold transfer and also to match up to the pipe line insulation.

The cold shoes are painted in-house as per the client’s specification. The 5th photo shows the steel cradles hanging in our paint spray booth.

In the final photo, the cold shoe is assembled around a pipe spool in order to check fit up to the pipe as part of the inspection and quality assurance process.
