Our experienced staff in design and engineering department support our clients in all phases of their project, whether it is stress analysis, thrust block design, preparation of PDMS catalogues, pipeline installation and test procedures as well as project control and management.

Piping Department

Engineers use a variety of engineering softwares in order to design and model pipelines. PDMS which is used by our design engineers in the piping department is one of the most advanced and versatile softwares and is favored by design engineers all around the world when it comes to pipeline design.
Using PDMS (Plant Design Management System the specifications of onshore and offshore project and in respect with all engineering, design and construction details and requirements is analyzed and all required drawings such as isometrics and calculations are produced.
Today GRP pipes are the first choice of pipeline and industrial plant designers. GRP pipes are made of highly specialized raw materials which give to unique mechanical properties. The dimensions of GRP pipes and fittings vary from producer to producer based on production method and technology. Therefore it is important to use the correct dimensional parameters of GRP pipes when using PDMS. For this reason and in order to assist our clients for their in-house engineering departments, an extensive list of dimension and mechanical property of GRP pipes and fittings is prepared in the form PDMS Catalouge. 
Generally in above ground piping systems a wide range of supports are used. The main roles of pipe supports are: to uphold the weight of the pipes and firings, accessories, fluid in the pipe, and also to protect the pipeline from excessive mechanical forces. Type, location and support distance depends on many factors. 
GRP pipes are supported using hangers or cradles made of concrete or steel and metallic belts and clamps. In order to prevent the outside structure of the pipe from abrasion, rubber pads are placed between the clamps and the outer section of the pipe. 
To control the expansion and contraction of pipelines two main systems are used:
(1) Expansion loops
(2) expansion joints.
Design of the expansion joints and expansion loops are based on stress in accordance with ASME B13.3 and AWWA M45.
Following diagrams show the modeling of expansion loop and placement of supports around it. 
With years of experience and using the most advanced technologies and softwares , our piping department staff are prepared to guide and assist you with all of your pipeline design requirements.

Civil /structural Department

An integral part of any pipeline design and installation is civil activities. No pipeline can be successfully installed and remain in operation without paying meticulous attention to the environment which it will operate in. 
Farassan Man  & Ind Co. provides the following services through its civil engineering department:

  • Comprehensive thrust block calculations and details of construction for above ground and underground pipelines.
  • Construction Drawings.
  • Detail Drawings for special installation cases such as : sub aqueous installation; casing of GRP pipe; Pipe-jacking and trench less installation; pipeline trench, bedding and back fill details
  • Design of pipeline support
  • Design of manhole and inspection pits.
  • Technical and financial Comparative analysis of GRP pipes with other piping systems based on project specifications.
  • Drop calculation

Hydraulic and Process Engineering Department

Leave your process and hydraulic design and calculations to us. Our exports in process engineering department are equipped with the knowledge and the most advanced computer software such as CIVIL3D and Water James to design all of your pipelines and processes. Review of operating parameters such as Temperature, pressure, corrosiveness, and fluid type is done in the initial part of design. Modeling and hydraulic calculation is followed in the next stage in order to provide a complete profile o f the pipe line such as:


  • Fluid dynamics
  • Surge pressure and vacuum calculations
  • Diameter selection
  • Placement of pipeline accessories such as valves, and control instruments
  • Complete P&ID and PDF documents.
  • Pressure drop
  • Pumping station design

Taking advantage of flexibility in production of different grades of composite (GRP/GRV/GRVE) Uniaxial and Biaxial pipes in our production facilities, our hydraulic department works closely with our civil engineering department to design and offer the most economical solutions for all types of pipeline .

Project Control Department

Our Project Control team is there to help you finish your project on TIME and on BUDGET.
In order to avoid any unwanted issues and conflict during the execution time, we pay close attention and spend most of our time in planning phase of the project. That is the reason why our Project control time can easily monitor and control all phases of projects, from production of the pipes to installation and commissioning.

Project Management Department:

From the very beginning of receiving an order or inquiry, our Project Management Department (PMD)work starts. Our experienced project management staff use all the knowledge, skills, tools, and techniques to project activities to meet the project requirements. Here is a brief list of general activities routinely undertaken by our PMD:

    • Review of technical and specification requirements of project.
    • Assuring that our range of products and capabilities corresponds to customers requirements without any deviations.
    • Conducting regular meetings with the clients to foresee any possible bottle-necks during the execution of the project.


  • Working closely with our R&D department to design new products based on customers’ needs and requirements.
  • Reviewing the technical and financial offers with the client.
  • Reviewing the initial draft of the contract in order to make sure all of clients’ requirements are met.
  • Assuring that the client receives all the financial and technical guarantees and warranties regarding the project.
  • Conducting Kick Off meetings and Pre Inspection Meetings, to assure completely understanding of the clients’ needs and requirements.
  • Providing all ITPs, TPAs, QCPs and other documents to the clients.
  • Organizing any inspection as mandated by the customers.
  • Overseeing issuance of Packing lists(PL), Manufacturer Certificate of Compliance (MCC), Inspection Release Note (IRN), Shipping Release Note(SRN), Coordination Report Form (CRF), Final Data Book (FDB).


Tender and inquiry Department:

Every single customer is important to us. Regardless of the quantity of order or the size of the tender, our staff at the Tender and Inquiry department prepares the most attractive financial offer; propose most economical composite pipe and grade of raw material for the project.
