Pipe Fitting Inspection & Testing

Thaum lub sij hawm tsim ntau yam Kev Tshuaj Xyuas & Kev Ntsuas yog nqa tawm ntawm cov yeeb nkab haum kom ntseeg tau tias cov khoom zoo.

Hydrotest rauCov yeeb nkab fittings

• Hydrostatic Test Tsis tas yuav tsum tau rau cov yeeb nkab fittings tshwj tsis yog thov los ntawm cov neeg yuav khoom
• Txoj cai tswjfwm uas fittings yuav tsum muaj peev xwm tiv tau raws li qhov xav tau los ntawm Piping Code.
• Cov neeg yuav khoom feem ntau tau txiav txim siab, tias lub plhaub taum ntsuas hydro tau siv los tsim cov khoom siv.

 

Pov thawj Test

Brust Test Proof Test

Txhawm rau tsim nyog rau kev tsim cov yeeb nkab haum, cov chaw tsim khoom tau ua ntau yam kev sim nrog rau kev sim tawg kom ntseeg tau tias kev tsim yuav ua tau raws li txhua tus qauv & cov cai. Hauv qhov kev sim no, ib lub yeeb nkab & fittings yog welded thiab ib tug dummy yeeb nkab spool yog npaj. Cov yeeb nkab spool no yog ces pressurized rau pre-txhais xam burst test siab. Yog tias cov fittings tiv taus qhov kev sim, tag nrho cov khoom lag luam yav tom ntej uas tsim los siv cov qauv tsim yuav txiav txim siab siv kev nyab xeeb.

Lap Joint stub xaus raug zam los ntawm cov ntawv pov thawj kev xeem vim tias lawv siv nrog flange sib dhos thiab tsim los txiav txim siab qhov ntsuas qhov ntsuas kub.

Kev kuaj tsis raug

Raws li hom fittings ib qho ntawm cov kev kuaj uas tsis yog-Destructive nram qab no yog ua nyob rau hauv tiav fittings los xyuas kom meej lub suab ntawm cov khoom.

• Ultrasonic
• Radiography (tsuas yog rau Weld)
• Sib nqus particle test
• Kev kuaj kua dej nkag
• Thiab Kev txheeb xyuas cov khoom zoo

 

Kev kuaj kev puas tsuaj

Kev kuaj kev puas tsuaj yog ua los xyuas lub zog ntawm lub cev thiab vuam ntawm cov khoom.

• Qhov kev xeem ntawv pov thawj tseem hu ua hom kev xeem lossis kev xeem tawg.
• Tensile xeem
• Impact test / Charpy V-Notch Test
• Kev kuaj Hardness

Kev Ntsuas Metallurgical

 

Kev Ntsuas Metallurgical yog ua los ntawm fittings lub cev thiab weld kom paub meej tias tus qauv yuav tsum tau ua

• Micro Analysis lossis Chemical Analysis ntawm
  • Cov khoom nyoos
  • Khoom
  • Weld
• Kev Ntsuam Xyuas Macro
  • Weld

Kev Ntsuas Metallurgical

 

Kev kuaj tshwj xeeb

 

• Kev ntsuam xyuas tshwj xeeb yog ua los ntawm fittings kom paub meej tias nws muaj peev xwm tiv taus nyob rau hauv ib puag ncig corrosive. Cov kev xeem no yog
  • IGC- Intergranular Corrosion Test (SS)
  • Ferrite (SS)
  • HIC- Hydrogen-induced Cracking
  • Thiab SSC- Sulfide Stress Corrosion Cracking
  • Cov nplej loj (AS & SS) ntawm cov khoom raug kuaj xyuas kom paub meej tias microstructure

Kev kuaj tshwj xeeb

 

VISUAL INSPECTION

 

Kev tshuaj xyuas qhov muag yog ua los ntawm fittings los xyuas txhua qhov tsis zoo ntawm qhov chaw. Ob leeg fittings lub cev thiab weld raug kuaj xyuas seb qhov pom qhov tsis zoo xws li dents, tuag marks, porosity, undercuts thiab lwm yam. Txais raws li tus qauv siv.

Pipe Fitting Marking

 

Hauv qab no yuav tsum tau cim rau ntawm Fittings

• Chaw tsim tshuaj paus logo
• ASTM cov ntaub ntawv code
• Khoom Qib
• Loj, rau tee loj ntawm ceg & khiav yeeb nkab thiab rau reducer loj ntawm ob kawg
• Thickness (Schedule No) rau ob qhov kawg yog tias lawv txuas nrog cov yeeb nkab thickness sib txawv
• Thaum tshav kub kub tsis muaj
• Kev ua raws cai - rau cov qauv fittings -WP, rau tshwj xeeb fittings S58, S8, SPLD thiab lwm yam.
