API 5L po'lat quvuri - 5l liniy trubkasi qatoriga ham ma'lum. Chakka po'latining pastki qismini o'z ichiga oladi: GR.B, X42, X46, X46, X46, X46, X60, X60, X70, x70.
Chiziq quvuri neft va gaz sanoat korxonalariga quvurlar orqali ekilgan neft, gaz va suvdan qazib olingan suvni tashish uchun ishlatiladi. Chop etish quvurini o'z ichiga oladi, ikkalasi ham, payvandlangan po'lat quvurni o'z ichiga oladi, tabrik tugaydi, timsetli va rozetka uchi va rozetka tugashi. Ulanish usullari payvandlash, ulanish ulanishi va soket ulanishi kiradi.

Gidrostatik test
API 5L trubkasi payvand choki yoki quvurlar tanasi orqali oqmasdan. Quvurlar orasidagi maskanlar, ular ishlatiladigan qismlar muvaffaqiyatli sinovdan o'tgan gidrostatik testni bajarishga hojat yo'q.
Bend sinov
Yoriqlar sinov namunasining istalgan nuqtasida sodir bo'lmasligi kerak va payvandning ochilishi ham yuzaga kelmaydi.
Iltimos, diqqat qiling: barcha egilgan sinovlar uchun payvand Fusion chizig'ining har ikki tomonida (0,25) masofani (0,25 ichida) uzaytiradi.
