The EMT-WRTV retrievers have following unique features: ● Only cleaned but not disassembled after use. ● The gear drive machines allow all operation to be performed in a minimum clearance area. ● The deft plug adapter and the spring load socket adapter make operating process easier to handle. The EMT-SGV service valve is gate valve Features: 1. Always to open 100% when you need to open. 2. Light in weight. 3. More easy to operate. 4. Easier to maintain.

Hydrogen probes detect hydrogen gas by the hydrogen pressure increase produced in an seal space in steel, i.e. the same mechanism as hydrogen blistering. The pressure build-up is directly proportional to the amount of infiltrate of atomic hydrogen, which can be determined by relationship of the ideal gas law.

EMT-CI Corrosion Coupons are used to monitor the corrosion rates of sample ( coupon ) in the pipe or container. By observing the mils-per-year corrosion rate of an exposed coupon, valuable information can be provided regarding the material's life expectancy.

The Model EMT-RCC Corrosion Coupon Holder Assemblies provide a retractable to 1500 PSI/10.3 MPa and temperatures up to 500℉/260℃. Insertion of the coupon holder can be adjusted to permit coupon positioning at precisely the desired point within the process. Standard lengths are available in 18, 24, 30 and 36 inches. The single tongue of the coupon holder allows the use of one or two strip coupons insulated or uninsulated. All coupon holders are supplied complete with mounting hardware for the coupons. A safety clamp assembly is recommended at pressures above 100 PSI and temperatures above +150℉.
