Stress AnalysisA Stress Analysis is a series of computer-assisted calculations, carried out by means of the Caesar IIprogram, withthe aim of designing a safe and optimized pipe support system.

Checks are carried out to ensure that the piping complies with the standard load cases: operating, sustained,thermal, wind, snow and seismic. Numerous variables are also taken into account, such as the forces acting onequipment (for example, pumps, filters or vaporizers) or on the supports themselves.

Finally, the complete documentation is produced, which includes the stress report, showing forces and nodaldisplacements, as well as isometric drawings indicating the type and location of each support.

Primary SupportsA standard document is produced for the support system, which is specifically designed for each project. Thisincludes the constructive and geometric features of the supports and the design of the bases, stops and guidesupports.

Secondary SupportsDepending upon the type of plant, it may be necessary to include metal structuresor profiles in order to fix the primary supports to the civil works structure.This is done by means of a secondary support system, which is designed bydefining sections, profiles, heights and distances to the primary or main support. Theconstructive details and joints between all of the different elements are also designed.

Above Ground Supports for Civil Works ProjectsFor certain projects, due to the relief of the terrain, the GRP piping runs both underground and above ground. Inthese cases, a special system is designed, composed of metal suppor ts, concrete supports, or a combination of thetwo. The study which is carried out determines the best solution for the client, from both a technical and economicalpoint of view.

Special Supports for Culvert PipesIn the cases in which a pipeline meets a road, motorway or any other type of infrastructure, systems are designed

in order for the line to cross these elements without them being adversely affected. Therefore, culverts are built inone of several different materials (concrete, steel, etc.) and the pipe is nested inside it. In this case, the culvertmust include a support system, designed in accordance with the parameters of the project (diameter and pressurerating), the joint system between pipes, the geometric features of the culvert, etc. In this way PROTESA is able todesign GRP culvert pipes of up to DN 3200 and PN 30.

Concrete Thrust BlocksAny change of direction in a pipe must be restricted by means of a concrete block. In order for these systems to bedefined, their geometric dimensions must be calculated based on certain determining factors, such as the terrain,the pressure rating, the diameter of the pipe or the angle involved in the change of direction.

There are several different installation set-ups that affect these calculations and, therefore, we are able to providevariations for single or multiple underground pipelines and designs for horizontal or vertical changes in direction,

or a combination of the two.Once the calculations have been made, a document is issued in which the constructive procedures and typicalframework structures are also defined for this type of element.

Hydraulic CalculationsThis study is carried out with the aim of analyzing different variables, such as water hammer, vacuum pressure orflow velocity, in order to optimize the dimensions of the pipe and ensure that it is sufficiently protected.

Burial AnalysisThis analysis is carried out using the AWWA Manual M45 2nd Ed. for underground piping under load conditions, dueto static weight, road crossings, groundwater or soil load at the crown of the pipe.

The calculations can be used to validate the installation, in terms of both pipe design and civil works parameters.

Having obtained the results of this simulation, recommendations can be made as to how the pipes should be buriedon site, such as the type of backfill material to be used and the degree of compaction, amongst other aspects.

Pipe Settlement and Connections to Rigid Elements

Depending upon the type of ter rain and whether or not the installation involves a transition to a rigid structure, suchas a concrete block or an inspection chamber, a study must be carried out as regards the displacement of the pipethat would occur in the case of differential settlement.

This displacement causes different mechanical effects on the piping, which can result in rupture due to shear stress.In order to counteract this, various solutions are studied, such as, for example, the installation of rocker pipes, theuse of Bell & Spigot joints or EPMD expansion joints and recommendations may even be made for the civil worksto be carried out under certain determining conditions.

Technical SpecificationsEach project is studied specifically and individually. For that reason, it is necessary to create a document whichspecifies all of the constructive dimensions and technical characteristics of the piping and fittings involved inthe project.

SpoolingIn order to break down the planned piping system of a particular project into the dimensions required for theproduction of each individual pipe or spool, an isometric breakdown drawing is generated, which divides the line up

into pieces that can be individually constructed and transported.

PROTESA is a Spanish company, founded in 1959, which is

dedicated to researching, designing, producing and installing GRP

(Glass Fiber Reinforced Polyester) pipes and fittings.

The three main sectors in which the Company is active are the

water treatment, power plant and large water network sectors.

From the beginning, the Companys services have grown, in both

an efficient and qualitative manner, according to the demands andrequirements of its clients.

PROTESA Engineering was born out of the desire to provide

solutions for the requirements of civil and industrial contractors

as regards engineering and technical consultancy.

PROTESAs teamis therefore made up of highly qualified engineers,

who, amongst other profiles, have wide experience in the study

and design phases of a project, as well as in project management

and site operations.

Subsequently, once the feasibility of the project has been confirmed,

PROTESA is able to provide comprehensive management and

leadership servicesfor its implementation.

This field of activity includes the management of the project

throughout its different phases: the planning of activities to be

carried out, the engineering processes as well as basic and detailed

engineering, procurement and contract management, control of

costs and lead times, supervision of the installation, commissioning,

quality control and all the official and legislative documentation that

needs to be considered.

Project Management

In general, projects tend to have a long life-cycle and PROTESA

has the capacity to take on the leadership of any project in

its entirety and all its complexity, from the design and planning

stage up to the commissioning of the installation, backed up by

the guarantee of numerous references and a multidisciplinary

team.

The main line of action is based on rigorous methodology, with a

commitment to value-addedmanagement practices, in orderto achieve high quality at the minimum possible costand meeting the requirements and expectations of the client.

At the initial stage of the project, PROTESA carries out a rigorous

estimated cost analysis and technical and economical feasibilitystudy, as well as producing a pre-project report.

In addition to its engineering and consultancy services, PROTESA also specializes in turn-key projects, providing a comprehensiveservice for project execution which includes the initial study, the design of the piping and fittings, their manufacture, finished product quality

control, shipment and on-site installation, as well as the hydraulic pressure tests.Each project requires its own study and for that reason, PROTESA designs a personalized product for each case, meeting themarkets most demanding international standards.
