Ethylene units in refineries and petrochemical plants require reliable and durable steam control valves to regulate steam temperatures for process control. At a leading Chinese engineering company’s ethylene unit, operators replaced failing valves with steam converting valves that feature a unique steam atomization design.

RPV, the “worldleading valve stockist”, has supported their customers globally with Goodwin International dual plate check valve stock from their facility in Suffolk, UK for over 20 years to date. With over 7,000 comprehensive product lines stocked, RPV recently added to this extensive valve stock with a multi-million order of Goodwin’s nonslam axial flow check valve.

The factory extension of the biggest fish smoking plant in the Nordic countries was completed last year. Vexve’s and Naval’s shut-off and balancing valves are an integral part of the energy-efficient heating and cooling system of food production.

Established in 2001, Actuatech started the production of its pneumatic part-turn actuator with the purpose of servicing valve manufacturing companies and pneumatic flow control specialists. The company states it has focussed on high quality for the export market. “We have built our market share on excellent reputation for quality products and on time service”, says the company.

A new autonomous subsea resettable valve, designed with corrosion resistant materials, will enable operators to quickly disconnect a range of applications in times of emergency.

Corrosion leads to maintenance issues and downtime which in some cases considerably affects ROI and equipment availability. Selecting the proper alloy for a given application, for example seawater-contact applications, is therefore an important step. The purpose of this article is not to detail all corrosion scenarios but rather present the main properties of Nickel Aluminium Bronze (NAB) Alloys to consider them early in design stage.

The drill and tap (D&T) repair process has been used commonly in the refinery, petrochemical and chemical plant sectors (downstream) for more than 60 years. D&T repairs have been performed effectively and safely to repack valves of various types. One of the unique characteristics of a D&T repair is that it is performed under pressure with the line still in service, allowing the valve owner/end user to continue normal plant operations.

The primary function of the bolt(s) in a bolted flange joint (BFJ) is to transfer the energy of the loading mechanics into a clamping force that ensures the BFJ reliably performs its role during operating conditions. Part 1 of this 2 part article discusses several of the fundamental properties of bolts and bolt studs and some of the common challenges to developing and maintaining a successful clamping load.

iSmart is in-service maintenance and repair technology. It is all about safe, smart operational management and maintenance on a running plant. To be able to implement iSmart, auxiliary equipment needs to be installed on the valves.

The Wm Powell Company (Powell Valves) has stood at the forefront of innovation since its foundation in 1846. As a leader in pioneering technology in the industrial valve market, Powell has provided valves to NASA, could boast being Thomas Edison’s valve of choice and is a leader in quality. The company has a rich history of achievements that has resulted in their continued success over the past 174 years.
