  • Gas quality bladders are medium weight to reduce bulk, with a maximum operating temperature of 70°C.
  • Computerized crimped joints ensure secure connections.
  • Fittings are ¼” BSP for diameters up to 16” and ½” BSP for 18” and above.
  • All stoppers are leak tested in accordance with ISO 9001 quality management systems.
  • Maximum inflation pressures are specified, with mechanical support recommended to prevent movement.
Important Recommendations:
  • When using argon, ensure effective ventilation of the space.
Dimensions and Pressure Specifications: The document includes a detailed table listing the dimensions, maximum seal diameter, length, minimum access diameter, maximum inflation pressure, and unit weight for each product reference from SGB2/FL to SGB48/FL.

Flameshield Gas Stopper-1

Palloni Otturatori per Saldature Flameshield Gas Stopper Gli Stopper gonfiabili del tipo Flameshield, Mod. SGB sono costruiti per diametri dal 2" al 84" e sono rivestiti esternamente per alte resistenze e possono essere forniti completi di protezione anti-scintilla. Di serie vengono forniti senza tubo di gonfiaggio, che può essere fornito su richiesta completo di manometro e valvola. Su richiesta è possibile avere anche di dimensioni maggiori e/o costruiti in altri materiali per essere utilizzati su particolari fluidi. Caratteristiche : ➢ Copertura esterna in canvas ad alta resistenza ➢ Costruiti con gonfare in corda ed occhielli in ottone per facilitarne il recupero ➢ Camera d’aria costruita in materiale ad alta qualità per utilizzo su gas - Peso medio per ridurre la massa (temperatura massima di esercizio di 70 °C) ➢ Saldatura delle Giunture controllata con computer ➢ Raccordi da ¼” BSP per diametri fino a 16” da ½” BSP per diametri da 18” e oltre ➢ Tutti gli stopper vengono testati per verificarne l’assenza di perdite, prima di andare in consegna, in pieno accordo al nostro sistema di controllo qualità ISO 9001. ➢ Le massime pressioni di gonfiaggio sono riportate nella tabella sottostante e corrispondono alla massima pressione che gli stopper possono tenere, tuttavia può essere richiesto un supporto meccanico in aggiunta per fare ulteriore tenuta sull’eventuale movimento. ➢ Ed è stimato in base alle formule inglesi della National Grid che assicurano che gli stopper possano avere perdite solo oltre i 30 l/m. Importante : Quando viene utilizzato l’argon, raccomandiamo sempre l’utilizzo in spazi aperti o ventilati The Flameshield type inflatable Stopper, Mod. SGB are built for diameters from 2” up to 84” and are externally coated for high resistance and can be supplied with anti-spark cover. The Standard Model is supplied without inflation hose, which can be provided on request complete with pressure gauge and ball valve. On request it is also possible to have larger and / or constructed in other materials to be used on particular fluids. Specification: ➢ Heavy Duty Flameshield Canvas Outer Cover ➢ Draw Rope Loops with Brass eyelets to aid retrieval ➢ Gas Quality Bladders – MEDIUM WEIGHT to reduce bulk (max operating temperature 70 C) ➢ Computerised Crimped Joints ➢ Fittings are ¼” BSP up to 16” & ½” BSP for 18” and above ➢ All Stoppers are leak tested prior to despatch in accordance with our ISO 9001 Quality Management Systems. ➢ Max Inflation pressures noted below and corresponding Max holding pressures however, mechanical support may be required to stop movement of the stoppers. This is estimated using a National Grid formula that ensures the stoppers would only leak past the stopper less than 30 l/m.
