In 2008, 2009, 2015 and 2016 output fell in the majority of steel-producing countries as a result of the global recession. In 2010 and 2017, it started to rise again. Crude steel production contracted in all regions in 2019 except in Asia and the Middle East. India is the 2nd leading producer of iron and steel industries. [citation needed]
Production casing is the final casing string set in a well and usually reaches from the surface to Target Depth (TD). The type of casing used depends upon the different conditions in the well. Commonly, production casing sizes range from 4 + 1 ⁄ 2 in (110 mm) to as large as 9 + 5 ⁄ 8 in (240 mm). It is the last string cemented in a well ...

A tube well is a type of water well in which a long, 100–200 millimetres (3.9–7.9 in)-wide, stainless steel tube or pipe is bored underground. The lower end is fitted with a strainer, and a pump lifts water for irrigation. The required depth of the well depends on the depth of the water table.
Pipe of differing strengths often comprises a long casing string, which typically will have the greatest axial tension and perhaps highest internal burst pressure differentials in the upper parts, and the greatest collapsing loads deeper in the well from external pressure vs lowered internal pressure.
The production of over 2 million tonnes (4.4 billion pounds) of steel for the Nord Stream 2 tubes resulted in more than 3 million tonnes (6.6 billion pounds) of CO 2 emissions, not including the concrete-coating and the associated pipeline sections onshore. [citation needed]
The mill was equipped with an electric furnace for generating steel from scrap metal produced from the waste of pipe and rail wheel production. The construction took 5 years and cost $700 million. [9] Interpipe began supplying steel to the United Arab Emirates (UAE) market in the early 2000s with up to 16% of global sales coming from this region.
The list ranks steelmakers by volume of steel production in millions of tons over time and includes all steelmakers with production over 10 million in 2021. The World Steel Association features a list from its members every year. Due to mergers, year-to-year figures for some producers are not comparable. Not all steel is the same.
