Engineering Services

Abu Dhabi Pipe Factory has a full-fledged Engineering Department, which can perform the following functions;

Design of Profile drawings for district cooling network which can be used for the construction of pipeline.

Designing of buried and aboveground fiber glass pipes according to AWWA C-950 and AWWA M-45 manual employing in-house software program. Design verification is done for the surge pressure, pressure class, allowable deflection, soil load and live load, buckling, combined strain, axial strain, buoyancy etc.

Creating Isometric drawings in Autocad format and generating Bill of Quantities for pipes, fittings, gaskets etc. Making spool drawings for pre-fabrication which will minimize material and installation time at site.

Stress analysis for above ground and under ground piping system using the most advanced computer program, CEASER II. The program will produce results in the form of deflections, loads and stresses through out the system from the input model created by the user and compare these results to their allowable limits.

Surge analysis using the software PIPENET Transient Module. It is a sophisticated computer program which analyzes water hammer in complex multi branch piping system under a variety of conditions. It can be used for predicting pressure surges, calculating hydraulic transient forces or even modeling control systems in flow networks.

Hydraulic calculation of pipe lines using PIPENET Standard Module. It is a powerful tool which can be used as an aid in designing a new network of pipes with appropriate pipe sizes and calculating the pressure loss occurring in different parts of the network. The piping system can be made up of pipes, ducts, pumps, fans, filters, valves, orifice plates, nozzles and pressure drop.

Design of Valve chamber, Thrust blocks, Anchor blocks and different types of Supports.

  Hydraulic Characteristics

The smooth inside surface of the ADPF fiber glass pipes results in low fluid resistance, which could lower the horsepower requirement for pumped systems. This characteristic could contribute to a substantial cost savings over the life of a typical piping system. The smooth interior allows the pipe diameter to be reduced while maintaining the desired flow.

  Buried Pipe Design

The Design calculations are carried out in accordance with AWWA-C950-95 and AWWA Manual M45. The structural design procedure for buried fiberglass pipe involves establishment of design conditions, selection of pipe classes and corresponding pipe properties, selection of installation parameters and performance of pertinent calculations to ensure that the design requirements are satisfied. The design calculations given on the left side are used to establish that the pipe meets the requirements.

  Aboveground Pipe Design
Aboveground installations are usually hung or supported. Restrained joints are used in nearly all aboveground applications. Only in case of well supported lines for non-pressure applications, an unrestrained joint can be used. Piping and its supports are designed as to accomplish both pressure and thermal length variation, plus bending load imposed by supports and spans. Changes of temperature, due to operation conditions or environment, give changes of length and end loading on GRP pipe, which have to be properly manufactured in order to keep values of stress and strain lower than the allowable ones.
