The Quality System implemented at S.I.F.E.A. since it first started business has become an increasingly integral part of Company life, being closely linked to the experience and professionalism developed over all these years.

Brilliant results have been forthcoming thanks to careful management of all resources - both financial and human - and an ability to solve the market's endless problems. All these challenges are faced with constant production improvement by virtue of investments that enable the Company to keep pace with technological development: for years, we have been investing in the constant maintenance of systems, as well as in training of technical personnel, and in compliance with laws on safety and hygiene in the workplace.

Certification of the Quality System is further evidence of S.I.F.E.A.'s commitment, and attests to the Company's efforts and quality-oriented approach, which have been recognized as conforming to standards.


S.I.F.E.A.'s welding processes have been certified with the following procedures:

Submerged arc and manual welding to European standard EN 288/3, which includes a range of thicknesses from 5 to 90 mm with stress-relieving and normalizing heat treatment for ferritic steels, and a range of thicknesses from 5 to 70 mm for austenitic steels.

Mixed manual - submerged arc procedure
Welding procedure to ASME IX from 6 to 40 mm without heat treatment and from 6 to 22mm with normalizing heat treatment (ASME II - SA 516-70 W.P.Q.R. TO ASME IX) - Lloyd's Register
