Built for Chemical Resistant & Hydrocarbon Pipe Applications
The Sava PLUGY C, PLUGSY C, and PLUGY NBR range is engineered to seal and test pipework from 40mm through to 1800mm diameter. Their overlapping multi-size design means fewer plugs are required on-site, helping crews work faster while reducing equipment inventory.
Manufactured with specialized chemical-resistant rubber compounds and reinforced with heavy-duty aramid cord, these plugs are specifically developed to withstand demanding conditions in refineries, food processing companies, and oil and gas networks while remaining highly flexible for insertion through tight access points.
| Feature | PLUGY C & PLUGY NBR – Blocking Plugs | PLUGSY C – Bypass Plugs |
| Primary Function | Designed for complete pipe sealing and isolation in environments exposed to aggressive chemicals or hydrocarbons. | Includes an integrated bypass, allowing flow-through capability or fluid diversion while maintaining a secure pneumatic seal in chemical lines. |
| Ideal Applications | Oil and gas pipeline maintenance and repairIndustrial plant and refinery shutdownsChemical process line isolationFood processing plant line isolation | Pipeline testing with aggressive chemical flow-throughTemporary bypass operations in industrial networksControlled drainage and hazardous chemical samplingRefinery and petrochemical asset maintenance works |
| Design & Capabilities | Robust aramid-reinforced construction and specialized elastomeric compounds (Chloroprene CR or Nitrile NBR) ensure maximum safety and a perfect seal when exposed to hazardous liquids. | Bypass configurations support flexible, high-volume flow management during critical, chemical-sensitive operations. |
