Structural carbon steel shapes are ideal for construction. National Association of Steel Pipe Distributors. “The Basic Oxygen Steelmaking Process.” American Iron and Steel Institute Steelworks Learning Center. Today the technology has changed, but the same basic principles of the Bessemer Process are still the backbone for modern raw steel production. Such thin-wall pipe – which has a wall thickness of about half that of EN 102552 type L2 ‘light’ pipe – is often joined using roll-grooved or press-fit type fittings that maintain a water seal using captured -rings.
As useful as steel was, it was time and labor intensive to produce, thus making it generally a poor material for mass consumption.

The tryst for continuous quality improvement is never-ending in N-PIPE SOLUTIONS INC. The hidden menace of corrosion in heating and cooling systems , BSRIA, accessed 10 August 2018. Geberit CPD presentation Precision carbon steel: how to stop the rot – truth or rumour?
Water-monitoring systems are now well established and, with new technologies being developed, the real price of such systems is reducing. The rate of corrosion and risk of failure depends on a variety of factors including the chemical and microbiological environment, temperature, flowrate and not least the thickness of the metal.6 Therefore, as well as ensuring appropriate installation techniques, proper maintenance and monitoring is required. Examples of low carbon steel press-fittings (Source: Geberit).
The pipework systems should be installed in accordance with the manufacturers’ guidelines by properly trained operatives. From pressurisation problems – negative pressures at the top of systems results in air being drawn in through air admittance valves (AAVs) or seals. In a closed system, the free oxygen in the initial fill of water will be used up in initial light rusting on the internal surfaces and, as long as that water is not replaced, there should be no source of additional free oxygen.

In the post-recession marketplace, carbon-steel sales continued to grow as the industry recovered and businesses re-established.
As shown in Figure 2, copper prices increased sharply in 2006 compared with those of steel. The press-fitting jointing system was initially developed in the 1950s for copper pipes, but it was slow to gain initial acceptance as, reportedly, the trade was reluctant to trust a method of connection that did not involve heat.
