Pressure Vessels Division

Thanks to more than 50 years of experience, ATB Riva Calzoni has become one of the leaders in the

design, fabrication and inspection of reactors and heavy wall pressure vessels utilized in Oil & Gas,

refinery and petrochemical plants operating in the most severe operation conditions of pressure and

temperature under hydrogen and corrosion attack.

In the early 70’s , ATB Riva Calzoni has been the first company in Italy to be qualified by ASME as an

authorized holder of S, U and U2 stamps for manufacturing pressure vessels for the United States

market. In the same years, ATB supplied 12nr hydrocrackers reactors in Cr – Mo material for the

EXXON Refinery in Baytown, Louisiana weighing more than 400 tons each .

Since 1960, ATB manufactured more than 1000 pressure vessels. Pressure vessels families

manufactured by ATB:

Reactors and Separators for “hydro-processing” applications

Ammonia shell converters and auxiliary vessels

Reactors for Urea production plant

CCR reactors

Coke drums

High pressure separators and drums for gas treatment plants

LNG cryogenic vessels 9%Ni material

Columns (heavy weight)

FCCU reactors/ Regenerators

IGCC Gasifier vessels

LDPE/HDPE separators

Reactors and separators for petrochemical plants (Polyethylene /polypropylene, HDPE/LDPE)

FCC reactors and regenerators

Acrilonitrile reactors

Steam Drums

Due to the continuous improvement required by refineries and petrochemical plants productivity, the

thickness, diameter and weight of reactors vessels have increased drastically and reached the limits

of the current manufacturing technology.

ATB policy is to focus on the most challenging jobs. Very powerful facilities and skilled workers made

it possible for ATB to specialize in the manufacturing of pressure vessels of exceptional

characteristics.

For reference, it has to be considered that up to now ATB has delivered equipment up to 358 mm

thickness and maximum weight in one single piece of 1400 tons. The main data can be summarized

as follow:

Thickness: HCK reactors of 358 mm

Weight: HDT reactor of 1400 tons

Length: C2C3 Splitter Column of 100 m

Temperature: CCR Reactor capable to bear 650° C – Columns capable to bear – 196° C

Pressure: Vessel capable to bear 46 MPa

ATB RIVA CALZONI SPA - P.IVA 01996991202

All qualities of steel produced to ASTM, DIN, British standards and to all western European standards

are widely used by the company in the fabrication of pressure vessels, and namely: carbon steel,

carbon steel with HIC properties, carbon steel for Low Temperature applications, all the qualities of

low alloy steels (1/2Mo, 1Cr 1/2Mo up to 2 1/4Cr 1Mo including the last developments of the materials

with enhanced properties and Vanadium modified chemical composition), steels for cryogenic service

9% Ni, stainless steel.

In today’s market ATB is worldwide well known as the leading manufacturer of heavy weight and high

thickness reactors for hydro-processing applications.

During more than forty years experience, ATB has been able to adapt their fabrication technology to

follow the customer’s reactors demand both in terms of increasing dimensions, thickness and weight

and of upgrading materials requirements

The evolution of thickness and weight involved in reactors manufactured by ATB since 1967 is shown

in the following diagrams.

In today’s market, Hydrocracker Reactors standard manufacturing technology is from forged rings.

However a special attention shall be paid to ATB’s capability to manufacture high thickness reactors

from both rolled plates and forged ring.

ATB is today operating one of the most powerful rolling machine which is enabling us to roll in

metallurgical cold conditions plates up to 260mm thickness. The above peculiarity provides to the

various engineering companies and end users an higher manufacturing flexibility that in today’s

market is a great added value to the traditional manufacturing capabilities.

It has to be outlined that in the early sixties ATB was the first company welding 2 1/4Cr 1Mo material

and that in the last years, ATB also developed the welding engineering relevant to last generation of

Vanadium modified materials such as 3Cr 1Mo 1/4V and 2 1/4Cr 1Mo 1/4V.

ATB is now one of the few companies qualified in the world capable to work extensively this V modified

materials. For your information ATB, up today first of Q1- 2012, has already delivered 44nr reactors

made with this material while other 7nr are currently on order / under fabrications.

Site assembly

The combination of continuously increasing vessels size/weight with the location of refineries and

petrochemical plants makes today more difficult to transport heavy and large equipment to the

destination plant.

Therefore it is today a common situation to be requested to manufacture the reactors/vessels in

sections in shop for an assembly to be made at site

In consideration of the above need but without having a dedicated site works divisions, ATB is today

one of the company experienced in making such site assembly of pressure vessels.

To this purpose we point out our experience made in the 90’s in supervising site assembly of several

Acrilonitrile Reactors in Chine for Tecnimont and of FCC Reactor/Regenerator unit in ExxonMobil

Sriracha, Thailand refinery.

The above experience has further improved in the recent years and in 2002 ATB made the site

assembly of a V modified material hydro-processing reactor at PEMEX. Tula refinery, Mexico,.

The challenge is today continuing as we are currently involved in two major projects that requires

reactors assembly at AGIP S.Nazzaro Refinery, Italy and Flying J Inc. Refinery Bakersfield Ca, Usa.

However the above business shall be considered only as an appendix to the reactors shop

fabrication and therefore all details conditions shall be carefully agreed so that maximum support shall

be provided at site by end users and engineering companies
