Kufanele i-PTFE Tape ibuyiswe? Ngaphezu kokuthi?
1.Tradisionele PTFE-tape, moet dit vervang word?
Ewe. I-tape yokuhlanganisa ye-thread yesiko iyaguga ngokuhamba kwesikhathi, kuholela ekwehleni kokusebenza kokuhlanganisa. I-tape eshiywe isikhathi ibonakala ihluleka, idala izikhala futhi ikhuphule ubungozi bokuvuza. Ukusetshenziswa kwesikhathi eside kungaholela nakho ekutheni ihlukaniswe ibe izingcezu ezincane ezingena emaphaketheni, zivalela ama-valve noma izingxenye ezinemininingwane.
Replacement Interval
Standard Lifespan:Teoretiese lewensduur is ~5–8 jaar. egter, faktore soos temperatuur, media korrosie, en meganiese vibrasie mag vroeë vervanging vereis.
Immediate replacement required if:
1.Uitloog: Stadige deurvloei van water/gas by verbindings.
2. Ukuphuka: Ithayi iba ukuphuka, ibhujiswa, noma ilahlekelwa ukuguquguquka.
3.Um contamination yeMazi: Izigaba eziphukile z contaminates amanzi (kubalulekile emigqeni yamanzi aphilayo).
Preventive replacement advice:
Non-critical lines (e.g., household water pipes): Inspect every 5–8 years; retain if leak-free.
Critical systems (gas, hydraulic lines): Overhaul every 3–5 years; replace if aged.
Replacement Procedure
Remove old tape: Soak threads in water, then scrub to remove residue.
Rewind tape: Clean and dry threads. Wrap 2–3 even layers counterclockwise from the root of external threads (moderate thickness). Avoid over-thickening, which prevents proper tightening.
2.Liquid Thread Sealant (Anaerobic Adhesive) – E necesita reemplazo?
Ngokujwayelekile akudingeki. I-sealant ye-liquid eyenziwe ngempumelelo yakha ipulasitiki ethokomele enokumelana okukhulu nokuguga (impilo ≥50 iminyaka). Ayincishiswa noma ihlukaniswe ngaphandle kokuthi ukuvikelwa kwehluleka noma kudingeka ukuhlukaniswa.
Replacement Scenarios
Seal failure: Cracking due to improper installation (e.g., uncleaned oil) or overtemperature (>150°C).
Maintenance disassembly: Verwyder residu deeglik (draadbors/spesiale oplosmiddel) voordat jy weer aanwend.
Material incompatibility: Accidental use on plastics/pure oxygen systems; replace with compatible material.
Uhlolo lwezokugcinwa
Post-installation check: Pressure-test after 24h cure (25°C); no maintenance needed if leak-free.
Extreme environments: For >150°C or strong corrosive media, consult manufacturers for specialty grades.
3. Ukuze uqinisekise ukuthi konke kuhamba kahle
Traditional thread seal tape:
Altijd met uniforme dikte tegen de klok in wikkelen.
Gebruik dit nooit op gasleidingen (vereist gespecialiseerde afdichtband).
Liquid thread sealant:
Vooraf grondig ontvetten voor toepassing (mag geen motorolie gebruiken; remt uitharding).
Bewerben Sie sich sowohl für interne als auch für externe Gewinde für Rohre >DN65.
