4. Перемещение труб по стеллажу вручную (диаметром до 150 мм) и электролебедкой (диаметром св. 150 мм).
5. Сборка секций с центровкой, правкой концов труб и поддерживанием при электроприхватке.
6. Откатка собранных секций на сварочный стеллаж.
7. Укладка в штабель готовых секций со строповкой, сопровождением и расстроповкой.

Примечание. При разметке труб диаметром св. 600 мм на каждое увеличение диаметра в 200 мм Н.вр. и Расц. умножать на 1,15 (ПР-1).
При резке труб
Состав работы:
1. Установка и закрепление трубы в станке или прижиме.
2. Резка трубы по готовой разметке.
3. Снятие заусенцев.
4. Снятие заготовок со станка или прижима и откладывание их в сторону.
