Ħarsa ġenerali
Aħna nżommu ntejbu u nipperfezzjonaw il-merkanzija u s-servizz tagħna. Fl-istess ħin, nagħmlu x-xogħol b'mod attiv biex nagħmlu riċerka u titjib għall-Pajp tal-Azzar Mekkaniku, B'vantaġġ tal-ġestjoni tal-industrija, in-negozju dejjem kien impenjat li jappoġġja prospetti biex isir il-mexxej tas-suq attwali fl-industriji rispettivi tagħhom. Id-devokazzjoni huma dejjem fundamentali għall-missjoni tagħna. Aħna dejjem konna konformi mal-klijenti li jservu, il-ħolqien ta 'objettivi ta' ġestjoni tal-valur u nżommu mas-sinċerità, dedikazzjoni, idea ta 'ġestjoni persistenti.
Applikazzjoni
Huwa Prinċipalment Użat għal mekkaniċi u użat biex jagħmel ċilindri tal-gass. jinkludu tubi mekkaniċi mingħajr saldatura tal-karbonju u azzar liga, u jkopri kemm tubi mekkaniċi mingħajr saldaturi lesti bis-sħana kif ukoll tubi mekkaniċi mingħajr saldaturi lesti fil-kesħa f'daqsijiet sa u inkluż 12 3⁄4 pulzieri. (323.8 mm) dijametru ta 'barra għal tubi tondi bi ħxuna tal-ħajt kif meħtieġ.

Rekwiżit tat-Test
1.Test ta 'l-ebusija
Meta jkunu meħtieġa limiti ta' ebusija, għandu jiġi kkonsultat il-manifattur. L-ebusija tipiċi huma elenkati fit-Tabella .Meta speċifikat, it-test tal-ebusija għandu jsir fuq 1 % tat-tubi.
2.Testijiet tat-tensjoni
Meta jkunu meħtieġa proprjetajiet tensili, il-manifattur għandu jiġi kkonsultat. Proprjetajiet tipiċi tat-tensjoni għal uħud mill-gradi l-aktar komuni u l-kundizzjonijiet termali huma elenkati fit-tabella.
3.Testijiet mhux distruttivi
Diversi tipi ta 'testijiet ultrasoniċi jew elettromanjetiċi mhux distruttivi huma disponibbli. It-test li għandu jintuża u l-limiti tal-ispezzjoni għandhom jiġu stabbiliti bi ftehim bejn il-manifattur u x-xerrej.
4.Flaring Test
Meta jkun hemm rekwiżiti speċjali għall-indafa tal-azzar, il-metodi tat-test u l-limiti tal-aċċettazzjoni għandhom jiġu stabbiliti bi ftehim tal-manifattur u tax-xerrej.
