SECTION TITLE
mechanism from coming into contact with the media and damaging the elements. Oil and gas industry operators often also need to consider how to best reduce membrane fouling and required maintenance. Traditional strainers, due to limitations in straining area, can become clogged quickly. When that occurs, cleaning, media replacement or backwashing is necessary, which adversely affects productivity as well as maintenance costs. In this regard, the multi-element design provides three to four times the surface area of traditional strainers and pre-filters. Tis translates directly into less frequent backwashing so less water goes to waste, less power is consumed and less maintenance is required. Traditional media found in large basket designs can lead to collapse and failure under differential pressures as low as 35 PSID. Te smaller diameter of the media used in the multi-tube strainers also enables the strainer to safely handle differential pressures in excess of 150 PSIG. Tis protects production even under higher differential pressures in the field, which could otherwise result in considerable downtime. As an additional protective measure, the strainers also include a shear key, which sacrifices itself in the presence of excessively large debris. So, if large debris were to cause mechanical problems within the strainer, the shear key breaks, protecting the unit’s rotating assembly, motor, and gearbox by halting the drive shaft rotation. Filtration continues, but operators notice an increase in differential pressure as the backwash cycle is interrupted, and can take action to clear the obstruction and replace the shear key.
UPGRADE OPTIONS For oil and gas environments exposed to highly corrosive elements such as seawater or salt spray, upgrade options to materials such as super duplex and duplex stainless steels, titanium, Monel, Inconel and Hastelloy can also provide further resistance to corrosion and corrosion-related damage.
When considering
technology for coarse filtration systems, automatic multi- element, self-cleaning filters are an increasingly popular choice and a reliable, cost effective solution.
