Sprinkler System Solutions

TA Banner Corrosion


Automatic sprinkler systems are used more than any other fixed fire protection system and the global fire sprinkler market is expected to reach $11.04 billion by 2020. The annual market growth is estimated at 9.36% between 2015 and 2020 with over 40 million sprinklers fitted worldwide each year.

Maintenance plays an important role 1, 2, 3. Clearly any interruption in functional availability can be crucial with lives and property at risk. Minimising maintenance times therefore has to be a priority.

TA Banner CorrosionSynopsis

During heat treatment surface oxide layers, usually called heat tints, are formed on precipitation-hardening nickel-based alloys like UNS N07718. These oxide layers are composed of elements that have been selectively oxidised from the base metal, principally nickel, chromium and iron.

The same phenomenon has been intensively studied on austenitic stainless steels. It is well known that the region beneath the oxide layer is depleted in one or more of the elements that are involved in the scale formation.

The Future for WAAM

CS Banner International success with weld purging of titanium alloy pipeAn acronym for Wire Arc Additive Manufacturing, WAAM is one of several prominent 3-D printing techniques where significant advances have been made in the last five years. Already established as an alternative production process in the airframe industry WAAM is now making an impact in other manufacturing sectors.

Already attracting massive investment across the world, a recent estimate of from the International Data Corporation indicates that global spending on 3-D printing will grow to $23.0 billion by 2022. This is an increase of over 23% from 2018. China, the UK and the USA spearhead the drive to exploit the potential for 3-D printing but Australia, India and the rest of Europe are also actively examining applications.

International success with weld purging of titanium alloy pipe - CS 417

CS Banner International success with weld purging of titanium alloy pipe

A new facility for the production of 1.25 million tonnes of terepthalic acid (PTA) has been built at the port of Mangalore in the Indian state of Karnataka 1.

The project involved factory fabrication of specialised equipment followed by integration on site. A range of stainless steels were used in manufacture along with titanium and tantalum alloys. The bulk of the fabrication involved welding of tubes and pipes.

A significant part of the project was awarded to a Chennai based customer of Weldwell Speciality Pvt Ltd 2 in Mumbai, a major supplier to the Indian welding industry for over two decades. The customer has a long tradition of specialist fabrication of titanium, tantalum, zirconium and nickel alloys and stainless steels.
