Галузь застосування
Технічні умови цього стандарту поширюються на безшовну холоднокатану та холоднотягнуту трубу, що виготовляються із сплавів титану.
Параметри труби немірної довжини
| Товщина стінки, мм | Довжина, мм |
| 0,5-0,8 | 800 - 8000 |
| більше 1 | 1000 - 8000 |
У кожній партії допускається трохи більше 10% виробів з відхиленнями по довжині, з припуском за кожен різ по 5 мм.
Допуски
Граничні відхилення по довжині труб (кратних та мірних) не повинні перевищувати +15 мм. На вимогу споживача допускається виготовляти трубу за внутрішнім діаметром і товщиною стінки. Граничні відхилення за внутрішнім діаметром встановлюються за погодженням виробника із споживачем. На вимогу споживача труби повинні виготовлятися з комбінованими граничними відхиленнями: діаметром - з відхиленнями звичайної точності, по товщині - підвищеної точності. Овальність труб з товщиною стінки 1 мм і більше повинна виводити труби за граничні відхилення по зовнішньому діаметру.
Різниця і кривизна
Різниця труб не повинна виводити параметри за граничні відхилення по товщині стінок. Кривизна на 1 м довжини має перевищувати 1,5 мм. Кривизна трубок діаметром менше 80 мм підвищеної точності виготовлення має перевищувати 1 мм.
