Hoogovens Innovates To Fill

Customer Needs

Hoogovens NV has been a leading marine materials developer in the quest to provide lighter yet stronger materials for marine applications.

As part of its program to develop advanced materials, a wrought Al-Mg alloy plate — which is significantly

Bend test according to

DNV-specification for a thickness of 8 mm, MIG welded with AA5183 filter wire. stronger than AA5083 — has been developed. Although stronger, the new alloy has corrosion resistance and formability similar to those of AA5083.

Welded panels of the AluStar alloy reportedly have a significantly higher yield and ultimate tensile strength with a similar level of ductility in comparison to AA5083 and AA5383 (after MIG welding).

The bendability of the Alustar alloy is demonstrated by both three-point and wrap-around bend tests.

FN Tape Puts Quick Wrap On

Various Problems

It provides easy application without special tools, is an alternative to metal shielding and offers what is touted as the best combustible oil splashing pre- vention in the industry. These features are functions of Nishiyama Corpora- tion's newest sales offering — FN

Tape.

With a 22-year-old U.S. subsidiary based in Great Neck, Long Island, the import/export trading company distrib- utes technical industrial products and machinery. Focusing on new maritime clients — while still remaining atten- tive to current customer relationships, the subsidiary began touting FN Tape about a year ago (Japanese Tokyo Nis- shin Jabara boasts as manufacturer of the tape) — its first product for the maritime industry. Intended to prevent the outbreak of fire caused by a splash of flammable oils, the tape shields a vessel's pipes from vibration, fatigue and pinholes.

By simply placing FN Tape over both pipes and joints, this safety measure is one that can easily be remedied.

Exhibiting both durability and worka- bility, FN Tape is composed of aramid woven cloth wrapped in superimposed aluminum foil for lamination. An adherent is then applied to one side of the tape finished off with a separator film.

FN Tape can tolerate high pressure levels up to 30 kg/sq. cm, and has a shelf life for an extended time period due to its exceptional oil/wear/weather resistance.

Developed in response to the Interna- tional Maritime Organization's (IMO) amendment of SOLAS regulation II -2 / 15. 2. 11, which deals with provisions related to this safety issue, a regulation was entered into force by the Organiza- tion on July 1, 1998 stating that all new ships giving off an output power of 375 kw must comply in order to meet this preventive safety rule.

After the effected SOLAS amend- ment, FN Tape also obtained an addi- tional Type Approval Certificate as requested by various ship classifica- tions societies, namely NK, ABS, LR,

BV, GL and NV.

In the wake of consolidation becom- ing a fixture in many industries, the company's marketing plan calls for tar- geting companies whose industry issues reflect upon regulatory and gov- ernment agencies, demand for new ships/vessels and condition of existing vessels — all driving forces in the demand for Nishiyama's FN Tape.
