GRP pipes
 

News :

For the Shipbuilding and the Offshore Industry, Iniziative Industriali offers a fully extensive range of GRP pipes and fittings tailor made at the highest quality level for an effective response to the even harder Shipbuilding World-wide competition. They are designed according to the international standards and to the IMO Regulations for the installation on board and use of GRP pipes and fittings.

Our systems combines the well known advantages of the composite materials (chemical resistance, light weight, very long lifetime etc.) with an extremely easy way of installation which does not include any glued or lamination joint to be performed at the Shipyard. The costs of installation are therefore suitable to be dramatically reduced because of the short time needed for bell and spigot joint connection and of the not strictly required availability at the Yard of personnel specifically trained on GRP piping material.

A HUGE RANGE OF APPLICATIONS FOR YOUR ONBOARD SYSTEMS

Our GRP piping systems are suitable for a various range of applications, as for example:

  • Cargo lines
  • Crude Oil and Washing lines
  • Inert gas
  • Ballast, Bilge and other Sea Water lines
  • Tank Cleaning
  • Sewage
  • Sanitary drains and other connected services
  • Potable water
  • Sounding and Vent lines
  • Any other according to IMO Regulation

OUR METHOD FOR GRP PIPELINE INSTALLATION

Iniziative Industriali applies the technology of the bell & spigot double O-ring joint which is the simpler and safer method of installation on board for a GRP piping system. Our pipes and fittings, fully prefabricated into spools, are supplied to the Shipyard complete of all the accessories such as gaskets and locking cables -and they are suitable to be mounted without the need to perform any laminated or glued joint at the Shipyard.

The combined use of GRP prefabricated spool and special GRP fittings such as flange adapters and sleeve joints makes the pipeline enough flexible to absorb both the mechanical and the thermal expansions, thus a very reliable solution for a safe ship lifetime.

EFFECTIVE QUALITY ASSURANCE

Given that all the prefabricated GRP spools are provided of bell or spigot ends, we are able to test all the pieces before delivery.

This is our guarantee: we check ourselves all the prefabrication work at our Factory and you are safe of any bad surprise when testing the whole piping system onboard. Through the years and the experience gained in connection with the most prestigious Shipyard World-wide we can affirm that this is the most advanced and reliable way to use composite pipes for the shipbuilding. To have an updated Reference List, please contact us.

SUPPLYING A FULLY ENGINEERED PACKAGE

As a standard way to do business, we include in our supplies also the detailed Engineering of the GRP systems and we provide you with a complete set of documents (Installation, Spools Drawings and Instruction Manual) which permit to handle, install and maintain the piping system in a very simple and easy manner.

The Installation Drawing reports all the GRP prefabricated spools by their own single marking code, therefore also not specifically trained GRP piping fitters can easily operate. This document is also inclusive of the type and location of the pipe supports. The detailed design of the supports is also available under request.

Send us, if available, your General Arrangement Drawings on AutoCAD® Format and we will return you all the Engineering Drawings included within the supply of the GRP piping system.

TECHNICAL CHARACTERISTICS OF GRP MARINE PIPING SYSTEMS
