Weld engineering designed for oil and gas projects

In addition, rapid traverse can be used for faster working. All of the control elements are easy to operate because they are integrated into the machine. The speed is initially adapted to heat exchanger use, but can be conveniently varied using a control valve. The feed can also be controlled continuously with a voltage divider. The robust, length-adjustable end switch stops the shortening process exactly at the desired position. Other special features include the balance setting, which is integrated into the handle for easy operation between the processing cycles. The exhaust air ring can be rotated, which allows the airflow to be kept away from the work piece and operator. The advantage of this is that an oil film does not form on the work piece – an unwanted effect that is often the cause for errors (pores and cavities) forming in the weld metal.

If size and tight tolerances require stress relieving after weld overlay cladding, even with large items of equipment, Arc Energy is able to carry out post- weld heat treatment in one of its own calibrated furnaces. Add to that the fact that Alan Robinson is himself one of very few UK registered International Welding Engineers, has a Masters degree in welding, and is a Chartered Engineer, a European Engineer and a senior member of the Welding Institute. All of which reinforces the fact that few welding specialists can equal this list of accreditations, or provide Arc Energy’s capability to support clients with a multi-disciplined welding, fabricating and engineering service delivered by highly qualified and experienced welding staff.

It is designed to be economical and ensures high levels of precision and quality when shortening and welding thousands of pipes on heat exchangers. The machine provides users with precision and efficiency during maintenance and service, and defective pipes can be easily ‘milled out’ of the pipe sheet. The cutting system for exact squaring and bevelling works with up to four low-cost cutting bits. Automatic hydro pneumatics are started when the touch control is activated. The BRB 2 clamps and centres itself in the pipe using compressed air, and the cutting process begins with hydraulic soft start. These accreditations are part of Arc Energy’s impressive list of qualifications, which also include ISO 9001:2008 quality management system, ISO 14001:2004 environment management system, Investors in People and OHSAS 18001 health and safety management system. Arc Energy also remains one of very few welding specialists that can boast accreditation to the ISO 3834-2 welding quality standard and conformance to the company’s significant investment in training and its commitment to meeting worldwide certifications and industry standards. Whatever a customer needs, from design for manufacture to final NDT, Arc Energy has the industry standard resource to exceed its clients’ expectations. In addition, Arc Energy holds ASME U and National Board R Stamps, enabling the company to provide code compliant equipment and pressure vessels for subcontract welding on free-issue ASME standard material.

HIGHLY specialised welding and complementary services such as fabrication, machining, corrosion protection and NDT in the oil and gas sector are available to meet the diverse needs of equipment suppliers manufacturing a range of components from pipelines and flanges to risers and pigging systems. However, finding all, or even a few, of these disciplines from a single- source supplier is rare as the need for an in-depth understanding of so many disciplines, and their equally wide and demanding quality standards, requires vast knowledge and experience. Yet Gloucestershire, UK-based weld overlay cladding and fabrication specialist Arc Energy Resources has successfully completed many projects that required just such a multi- disciplined approach. Commenting on the multi-disciplined approach to its welding service, man- aging director Alan Robinson stresses

Boiler pipe processing ORBITALUM Tools GmbH has

expanded its range for pipe cutting, bevelling/squaring and orbital welding with its new BRB 2 Full Auto boiler-pipe processing machine. The pneumatically operated machine is a suitable addition to the company’s WIG pipe-in-sheet weld heads.
