BELLOWS: DESIGN AND CALCULATION

STATE-OF-THE-ART ENGINEERING

Bellows: design and calculation

With our know-how and product range, we are in a position to offer our clients immediate solutions and high quality technical support.

All our expansion joints are studied and designed specifically to comply with our clients’ needs. We have achieved the highest safety standards by engineering products using reliable calculations, verified by state-of-the-art software.

We are authorized to affix the CE marking, indicating compliance with the Pressure Equipment Directive (2014/68/EU), to our products.

DESIGN

Expansion Joints are designed, analyzed, manufactured and tested in accordance with the following design process:

• DESIGN STANDARDS: EN 13445, EN 13480, EN 14917, PED 2014/68 / EU, ASME VIII, DIV. I, ASME B31.3, ASME B31.1, AD 2000 OR EJMA

• COMPUTER AIDED DESIGN (CAD)

• 3D MODELLING (INVENTOR)

• FINITE ELEMENT METHOD (FEM) (ANSYS)

• TECHNICAL CONSULTANCY TO FIND OPTIMAL SOLUTIONS FOR THE BELLOWS DESIGN, APPLICATION, PIPING SYSTEM POSITIONS AND INSTALLATION REQUIREMENTS

• CALCULATION SOFTWARE: EJMA / SANT’AMBROGIO

EXPENSION JOINTS DESIGN: APPROVAL

In cases where the bellows integrity under pressure is not validated by the results of the design calculations using EJMA standards and the geometric complexity indicates the need for further optimization of the project, Giorgi Engineering can verify the integrity of the product with finite element analysis (FEA), using ANSYS® software.

The technical approval and the results of the analysis obtained in accordance with the terms of the specified design standard are provided as a technical documentation package, complete with valuation reports.

Giorgi Engineering uses software that has been tested and validated in close collaboration with respected institutes such as TÜV, BUREAU VERITAS and LLOYD’S REGISTER who use it globally.

ADVANCED ENGINEERING AT YOUR SERVICE
CLIENT SATISFACTION IS OUR PRIORITY

We study the project specifications and interact closely with our clients to rapidly supply technical responses and solutions tailored to their requirements. Each project requires a custom-made solution. Our capacity to design, simulation and manufacture come from experience and specialization in different sectors to achieve our client’s satisfaction.

Cost optimization is a priority; we offer products with a high technical performance at the right cost. We can take care of any criticality that requires urgent substitution of the bellows.

QHSE

Giorgi Engineering is completing the certifications to comply with the highest QHSE standards.

Our priority is to implement and adhere to initial review processes of the specifications, including the design, production, test phases and documentation, in compliance with the client’s needs. In the short term, when testing and inspections will be done internally, we will be able to shorten delivery times and optimize resources.

CERTIFICATES

Company certifications:

  • EN ISO 9001: 2015
  • Pressure Equipment Directive 2014/68 / EU (PED 97/23/CE): Module H
  • EN ISO 3834-2
  • AD 2000 Merkblatt HP0
  • TR CU 032/2013 (GOST-R)
  • Declaration of conformity (from the Russian Federal Service for Environmental, Technological and Nuclear Supervision, Rostekhnadzor)
  • Type approvals: BV / RINA / LR
  • Standard approvals: Liquified Petroleum Gas (LPG) / Liquified Natural Gas (LNG) / Marine and Offshore

DOCUMENTATION

Over the years Giorgi Engineering has become increasingly attentive to the quality and extent of the documentation that accompanies its bellows.

The company has introduced a dedicated software to manage traceability of all the materials used in any specific order, integrating this with our design software and guaranteeing the integrity of all the materials used. The software also produces reports of the internal tests and quality inspections results.

The reports can be sent separately or supplied with the bellows, allowing the client to reduce facility downtime to the minimum before the installation.
This rapidity in supplying the documentation ensures that at the time of the offer the client already has all the technical details necessary to make an informed evaluation of the proposed standard and personalized solutions, such as the project specifics, Industry 4.0, and the project code.

Whatever the type of documentation required, from the simplest with just a few certificates to the most complex, Giorgi Engineering has the experience to guarantee compliance.

Bellows Reports:

  • CALCULATIONS
    We supply EJMA bellows calculations as standard documentation, which can be integrated with an analysis of all the component parts, including various methods of stress analysis, such as Finite Element Analysis (FEA) etc.
