GD.Engineering, an SPX Brand, is a market leader in design and manufacture of engineered pipeline pigging solutions to the oil, gas and process industries.
The Bandlock 2 Closure range provides speed of operation with safety benefits. Used on process vessels such as : pig launcher, pig receiver, all range of filters, strainers and separators.
GD.Engineering has many years experiences in providing innovative closure designs for a wide range of process applications.
The Pigalert Hi-T intrusive and non-intrusive MAGAlert and ULTRAlert pig signaler range, provide reliable pig and sphere passage indication.
Multiple Pig Launchers allow remote multiple pigs launching without depresssurisation.
The Company’s quality system is approved to ISO 9001:2008 by LRQA and they feature in the FPAL and Achilles Joint Qualification System. |

| Bandlock 2 Quick Opening Closure |
| Innovative Design Features |
Then GD.Engineering Bandlock 2, is the original and benchmark design for global high-pressure applications with over 20.000 units in operation worldwide. The Bandlock 2 Closures provide horizontal or vertical access to any pressure vessel in seconds. Compared with other quick-opening closure they can operated safely at remarkable speed – any size of unit opened or closed in less than a minute, with no special tool. |

| Integral Safety Devices |
Safety has been engineered into the Bandlock 2 at every stage of its design and manufacture.
A hand-operated pressure warning screw integrated into the mechanism prevents the door being unlocked until it is confirmed that the vessel’s internal pressure has been relieved.
Additional secondary safety features, such as mechanical key interlocks, can be fitted and integrated with control valve operations. |
|
| |
| Size and Pressure Range |
Bandlock 2 is available to suit differing vessel sizes and pressures from 6” to 100” diameters with hub sized for welding to any diameter and thickness, for any pressure from ASME Class 150 though to 2.500
(425 bar working pressure). |

| Hi-T Pigalert, for Scraper and Sphere Signalling |
| Operating Capabilities |
The Hi-T Pigalert is made in three pressure classifications – up to ANSI Class 600 and for ANSI Class 900 and 1500. Standards designed for use of temperature from -20°C to +200°C, dependent upon the line products and pressure. Alternative elastomer seals can be provided for operating temperature outside this range.
