In August 2010, LESER (www.leser.com) will introduce a new product series: the pilot-operated safety valve. Both pop-action valves (Series 810) and modulate-action valves (Series 820) are available.

The typical application areas of the pilot-operated safety valve (POSV) are refineries and gas processing plants, compressors in gas pipeline systems and offshore applications. The own-media-controlled POSV offers the advantage that the plant can be run close to the set pressure of the valve. This leads to an increase in the capacity utilization and consequently of the efficiency of the plant. Furthermore, POSVs allow higher external back pressures than spring-loaded valves.

By means of the harmonized standard DIN EN ISO 4126-4 pilot-operated safety valves are now also approved in Europe. For decades already their technology has been proven in the American market and in the Middle East.

The LESER POSV will be with a short four-week lead time ex works in Germany. As a special design feature, the tubing between the pilot valve and the main valve is integrated in the main valve cover, reducing the risk of damage or freezing. The backflow preventer is included as standard.

The POSV will be part of the new LESER product group High Efficiency. This group unites all products which increase the efficiency and the productivity of the plant.

Lokring Technology has released of a new Low Alloy Carbon Steel Solution for Sour Service applications.

The Lokring “333” Process Fitting is…

1. A NACE compliant fitting material (AISA 4130 NACE Grade Carbon Steel) tested to NACE TMO-177 Method A.

2. Qualified for use on A333 (LTCS) Piping (Charpy Impact tested to - 46º C (50ºF). 85% minimum shear)

3. Designed with a Corrosion Allowance of 1/8th inch or 3.2mm

Following extensive ASME Qualification Testing (Flexural Fatigue, Burst, Tensile & Torsion) Lokring have available Couplings from ½” to 2” presently available and weld-free ANSI Flanges in production. They are now qualified for use on A333, A106, API5L Grade B & A53 Pipe - Schedule 40, 80 &160.

Fittings will meet the criteria of NACE MRO175 / ISO15156 and MR0103-2007 for Refineries. Fitting Material Specification meets AISI /SAE 4130 (UNS G 41300) Low Alloy NACE Grade Carbon Steel Fittings have Blue Zinc Chromate plating to ASTM B633.

Typical Class: #150, #300, #600 & #1500
Temperature Range: -46º C (-50º F) to +204º C (+400ºF)

Lokring is a THE mechanical weld equivalent pipe solution that doesn’t require hot work. Fittings are rapid to install and are qualified to ASME B31.1 & B31.3 as well as Lloyds Type Approval. It is a proven solution within the Process Industry and provides significant reductions in total installation costs.

Elastic Strain Preload (ESP) Technology…
During installation, the axial movement of the LOKRING™ driver over the fitting body swages the body onto the pipe surface, compressing the pipe wall first elastically and then plastically. The pipe wall resists this swaging action, generating high unit compressive loads at the contact points between narrow sealing lands inside the fitting body and the pipe surface.

These contact stresses are sufficiently high to plastically yield the pipe surface under the multiple sealing lands, forming a 360 degree circumferential, permanent, metal-to metal seal between the pipe and fitting body. The driver, which experiences a small increase in diameter (elastic strain) during installation, exerts an elastic, radial pre-load on the metallic seals for the life of the connection.

– CRC-Evans Automatic Welding is announcing its new dual-torch external automatic welding machine for small-diameter offshore and spoolbase applications. The P625 offers leading-edge technology and outstanding weld quality in a compact machine that brings high productivity to offshore jobs.

Incorporating all the advancements that CRC-Evans is known for, the P625 is fully digital, with through-the-arc tracking and pulse MIG to maximize speed and produce the highest quality welds. Human error is taken out of the welding process because computerized monitoring and control keep the torch and bead in perfect position. From pre-weld programming to real-time operation to post-project assessment, digital technology takes care of accuracy and repeatable performance.

The P625 allows software to be upgraded in the field, so that changes in weld parameters can be made on the fly, getting the machine back to work quickly. In the office, a PDA user can program parameters and then download them wirelessly to the P625 on the job. Or data can be uploaded to a PDA in the field and taken back to the office for analysis and reporting. The P625 is also designed with scalable architecture that will accommodate future innovations, so that it can always be updated with the latest technology.
