ASTM A53 Grade A mpe B Tuyau ya bibende - BLOG

Bolimbisi ya biloko

ASTM A53 ezali spécification standard mpo na tuyau en acier carbone na ba taille nominale ya tuyau, oyo esalemi mpo na komema mayi, gaz, mopepe, vapeur mpe mpo na ba usages mécaniques mpe structurels générales. Ezali ko couvrir tuyau sans soudure, tuyau soudé ERW na tuyau soudé na four-butt, na niveau mibale ya makasi (Grade A na Grade B).
Octal Pipe epesaka ASTM A53 Grade A mpe Grade B na galvanisation optionnelle, ba finitions ya suka ndenge na ndenge, mpe certification ya moulin mobimba mpo na livraison ya projet.

Mitindo ya biloko

Lolenge S – Ezali na boyokani te

Pipe sans soudure oyo esilaki na molunge-esili to malili-esili. Elingi mingi pona ba systèmes ya pression, ba utilités ya usine pe service mécanique esika esengeli uniformité na nzela ya mur.

Lolenge E – ERW (Electrique-Résistance soudée)

Tuyau soudé longitudinal na chaleur ya soudure-traité ndenge esengami na spécification. Pona ya talo-efficace pona ba lignes fluides, ba systèmes ya moto pe ba applications structurelles.

Lolenge F – Four-Esoudée na butt

Ezali kaka mpo na Grade A. Esalemi mpo na mosala ya pete-ya mosala esika wapi botalisi epesi nzela na mosala oyo.

Ba notes

Kelasi ya A:makasi ya momesano mpo na mosala ya monene

Kelasi ya B:traction mpe makasi ya rendement ya likolo, mingi mingi elakisami mpo na pression mpe bosaleli ya masini

Grade B, oyo ezali na ba valeurs ya traction pe ya rendement ya likolo, ezali pona ya momesano pona ba lignes ya pression, ba systèmes ya moto pe service mécanique.

Fabrication & Contrôle ya Processus

ASTM A53 epesaka nzela na ba routes sans soudure mpe soudée. Ba tuyaux sans soudure esalemaka na molunge-mpe esalemi na bonene na OD oyo esengeli mpe na épaisseur ya mur. Ba tuyaux ya ERW esengeli kozala na soudure ya malamu, oyo ezali kolandana; esika ya soudure esalemi na molunge-tango elakisami mpo ete martensite oyo ekangami te ezala te. Tuyau soudée na butt ya four-ezali limité na Grade A.

Bolai ya pipe nyonso esalemi na:

inspection visuelle et dimensionnelle pona droit, OD, mur na surface
test ya hydrostatiquetoendimi ekzamɛ oyo ezali -ezali kobebisa te
ba tests ya flexion/plattage pona ba produits soudés pona ko confirmer qualité ya soudure

Niveau oyo ya contrôle ekomisaka A53 acceptable pona service fluide, gaz pe structurel na ba immeubles, ba usines pe ba utilités.

Hot-Option Galvanisée ya kozindisa

Ba tuyaux ASTM A53 ekoki kozala fournis na chaud-dip galvanisé na immersion. Zinc esengeli kokutana na ASTM B6, mpe masse ya revêtement esengeli te kozala na se ya ba valeurs minimum oyo elobami na ASTM A53. Esengeli kozala na revêtement continue, sans ba taches ya pamba, ba blisters na ba bosoto ya kilo.
A53 galvanisé ezali recommandé mpo na ba lignes ya libanda, ba services ya mayi mpe ya mopepe, protection ya moto oyo ezali exposée, mpe ba environnements industriels oyo esengaka résistance ya corrosion ya malamu. Octal Pipe ekoki kopesa ba tuyaux noirs na galvanisés à partir ya gamme ya taille moko, na vérification ya revêtement.

Ba applications ya momesano

Ba lignes ya mayi, gaz pe ya mopepe comprimé-na bandako, ba izini pe ba systèmes municipales
Ba services ya vapeur na condensat ya pression ya nse-
Bobateli moto-bobateli mpe ba tuyaux ya asperseur (esika ASTM A53 epesami nzela na norme ya système)
Ba membres structurels na mécaniques oyo esalelaka tuyau lokola ba colonnes, ba reculs to ba cadres
Service général ya pipeline na boîtier pona câblage/drainage esika API 5L esengeli te
