New antitamper lock for valves, actuators
By ensuring valves and actuators are only operated by authorized individuals, this new antitamper lock (ATL) helps secure assets by reducing the risk of human error or deliberate tampering.
The standard condition of the device in service is locked (key-free), with the handwheel free-rotating. The standard unit is available in two sizes to suit all lever and handwheel operated valves.
Operation involves three steps: 1) a coded key from the control authority is inserted, engaging the drive, 2) the valve is operated to the desired position, and 3) the key is removed and the valve is locked in the desired position.
Because the lock base adapter is machined to suit host equipment—which can be done on-site or supplied already machined to specification—the ATL helps reduce costs, the firm points out. Also as this process simply replaces existing handwheels or levers, the integrity of pressure envelopes is not compromised in any way.
Because the ATL is only installed and commissioned once, permit to work and lockout-tagout authorities can focus their attention on other matters rather than worrying whether someone has installed the lockout device correctly.
The housing is stainless steel coated with yellow polyester resin. For safety applications, the internal components are manufactured from stainless steel 304, with acetyl bearings, while for security applications these components are manufactured from hardened steel, with a protective security skirt. Both versions can operate in a temperature range of –58° F. to +212° F. (–50° C. to +100° C.).

New family of welding consumables
A new family of Pipeliner welding consumables is designed especially for the professional pipe welder and the demands of the global pipe welding environment.
The product group includes consumables for every arc welding process used for pipe welding or fabrication, including: stick, MIG, flux-cored, and submerged arc.
Electrodes are packaged in field-tested moisture-resistant containers that help ensure consistent performance, the company says.

Transmitter can use natural gas at remote sites
This firm's IPX2 current-to-pressure transmitter has obtained Factory Mutual intrinsically safe, nonincendive, explosionproof, and dust-ignitionproof apparatus certifications, including certification to use natural gas (up to 20 ppm of H2S) as its pneumatic supply in Class I, II and III, Division 1, Groups A-G areas.
This capability allows it to be installed at gas gathering stations, compressor stations, pipeline feed applications, and other locations where it is impractical or impossible to supply instrument air for pneumatic valve actuation.
This loop-powered unit accepts a current signal (such as 4-20 ma) from a DCS, PLC, or PC-based control system. It converts the current signal to 22 available pneumatic signals proportional to the input (3-15 psig, 0.2-1 bar, and 20-100 kPa).
The IPX2 is offered in a field-mount metal enclosure that promises to stand up to harsh field conditions. For installation in harsh weather conditions, it is rated to operate in low and high ambient conditions of –40° C. to +85° C. (–40° F. to +185° F.) with an IP56 (air) and IP66 (-NG) ingress protection and NEMA 4X ratings. The transmitter is accurate to ±0.25% of span, has air capacity of 5.0 scfm, and offers immunity to the effects of RFI/EMI and vibration.

New tool helps pull and align flanges
The SEAStallion Flange Pulling System is a new addition to a range of bolting products.
The fast, controllable tool helps pull and align flanges and heavy equipment.
To improve tool handling, it is lightweight and has an antislip surface; in addition, the hydraulically operated clamps allow for rapid setup and decommissioning.
The valve design incorporates a center hold position, allowing disconnect of down line without removing the pullers. This helps ensure no separation of the joint during periods of weather downtime or bell changeovers. The pullers can be operated simultaneously or individually, allowing the operator to control the alignment of the flanges during pulling operations.
The 18 mm Dyeform wire rope has been adapted to eliminate the possibility of strands falling under load.
The system is also available with a bar design for restricted access applications.
