API5L X42 ERW PIPE

Aplikasyon

Senaryo aplikasyon espesifik pou API 5L tiyo asye gen ladan yo:

1. Offshore lwil oliv platfòm konstriksyon

Itilize nan konstriksyon nan tribin lwil oliv lanmè tankou Lagrès, X70 asye klas Dwat Couture submerged ARC soude tiyo (LSAW) se itilize sipòte estrikti nan platfòm.

2. Long distans lwil oliv ak gaz sistèm tiyo

Li se lajman ki itilize nan mwayen ak ba presyon transpò nan lwil oliv ak gaz natirèl, ki kouvri anviwònman konplèks soti nan peyi a maren. Pou egzanp, klas asye diferan tankou x42 x80 ka satisfè diferan presyon ak kondisyon tanperati (egzanp x65 se souvan yo itilize nan pwojè LNG).

3. gwo tiyo presyon

API 5L tib asye nan klas asye segondè (egzanp x80) yo te itilize nan segondè-presyon lwil oliv ak transpò gaz, tankou tuyaux transkontinantal oswa gwo twou san fon lanmè lwil oliv ak devlopman jaden, ki egzije strik tès ki pa destriktif (egzanp UT/RT) asire sekirite.

4. Jeni anviwònman espesyal

- Anviwònman asid: asye rezistan souf (tankou C110) yo ta dwe itilize ak make ak yon "s" sifiks.

- Senaryo tanperati ki ba: Steel Klas X65/X70 se apwopriye pou transmisyon gaz nan zòn trè frèt.

- Sèvis Marin: tiyo asye make ak sifiks "O" satisfè API 17D estanda a ranfòse pou kanalizasyon platfòm lanmè.

5. Tiyo Minisipal ak Endistriyèl

Kèk espesifikasyon (tankou J55/N80) yo te itilize tou nan rezèv dlo minisipal, tiyo gaz ak sistèm chofaj, men yo ta dwe atansyon yo dwe peye nan distenksyon an ak tiyo asye estriktirèl.
