Inflatable Stoppers for Petrochemical Applications
Blocking pipes or other orifices to carry out routine maintenance and other applications can prove challenging where hydrocarbons are present in liquid and gas form .
Now , a range of hydrocarbon resistant Inflatable Pipestoppers is available for the Petrochemical and Oil and Gas Industries . Manufactured in cylindrical and spherical formats from 1 – 96 ” ( 25 – 2,440 mm ) in diameter with a high-grade latex , rubber internal inflatable bag covered with a petrochemical resistant layer , which has a tough , woven impregnated nylon outer cover for use up to 90 º C ( 194 º F ).
The versatile Inflatable Stoppers are used to service a wide variety of industrial applications . As “ overnight stoppers ” they provide a strong barrier in pipeline activities , to prevent foreign bodies entering the line during downtime . In machining applications , they can be inserted below a horizontal flange on a vertical pipe , to prevent machining fluid , swarf and tools from falling into expensive machinery such
as pumps and turbines etc . Inflatable Stoppers are particularly useful when one or more can be inserted into a small opening close to a work location , rather than at the end of the pipe , tank or vessel . No highpressure equipment is needed for inflation .
Manufactured by Huntingdon Fusion Techniques HFT ® these PetroChem ® Stoppers are available with optional heat resistant covers to protect them against high temperatures of up to 300 º C ( 572 º F ), ensuring the Stopper is not damaged when exposed to high temperatures . PetroChem ® stoppers are light in weight and easy to manipulate and can be shipped anywhere by next day courier at very low cost .

Launch of spiral pipe plant in Canada
Schuler helps steel and mining company EVRAZ to commission a line and to train the maintenance staff
In less than five months , Schuler and its customer EVRAZ have launched a spiral pipe plant in Regina , Canada . In addition , the forming technology specialist has spent three weeks training maintenance staff for software and hardware about the line and its components . EVRAZ had bought and relocated a line to Canada which was already installed in the USA .
For the modernization process , Schuler also supplied the coil cart and decoiler as well as all roller beams of the forming station with sophisticated technology .
At the heart of the decoiler are two coil stands , each with two servo motors and proportional valves . The line will be used to produce spiral pipes measuring 12.0 to 24.3 meters in length with diameters of 608 to 1,625 millimeters . The pipes will have wall thicknesses of 6 to 25.4 millimeters and weigh up to 24 metric tons . EVRAZ North America is a whollyowned subsidiary of EVRAZ plc , one of the world ’ s largest steel and mining companies . It is a leading North American producer of steel products for rail , energy and industrial end markets ..
