Трубы изготавливаются из материалов, способных (capable of) противостоять коррозии. Трубопроводы изготавливаются из бесшовных или сварных труб, причём их диаметр может меняться от 40 до 1000 мм.
Имеется тенденция использовать трубы с более тонкими стенками, но с большим диаметром. Использование труб большого диаметра имеет много преимуществ: они увеличивают пропускную способность трубопровода и уменьшают стоимость строительства.
В результате (as a result of) использования сварочных процессов в турбостроении протяжённость (the length) трубопроводов резко возросла. Средняя длина труб, производимых в настоящее время, составляет (is) 12 метров, однако трубы длиной 24 метра находят всё большее применение при строительстве трубопроводов. Толщина труб зависит от давления газа или нефти внутри трубы и протяжённости трубопровода.
