Darvico delivers SteamForm valves.
A Darvico spokesman told Gulf Industry the valves were Masoneilan 84K Series of size 18 x 18 inches (inlet-outlet) and that seven other valves of similar size had been ordered and were in the manufacturing process at the company's plant.
Also recently, Darvico produced and delivered to the Saudi Aramco Total Refining and Petrochemical Company (Satorp) project Masoneilan 41 K Series valves of four sizes ranging from 16 to 24 inches. The Satorp deliveries were heavy-construction, 3-tonne-plus valves, the hydro-testing, assembly, mounting, painting and other testing of which were completed entirely in-house at the company's plant with full mobilisation of its state-of-the-art test benches and robust handling facilities.
"Our capabilities in executing large and challenging orders have generated much customer confidence," the spokesman said. Darvico has a trained and experienced crew of assemblers, testers and calibrators who are annually recertified by Dresser's training manager.
Darvico, set up as a joint venture between Al Rushaid Petroleum Investment Company Ltd (Saudi Arabia) and Dresser Industries Inc. (USA), is implementing several other orders it won for upcoming gas plants in Shaybah and due for delivery next year. The plant is able to manufacture and test globe valves up to 36 inches and butterfly and ball valves up to 60 inches. By year's end it expects to assemble a number of 30-inch globe valves in addition to several hundred valves of smaller sizes.
Masoneilan 21K and 41K general service control valves are popular in the kingdom and used in several industrial sectors including oil and gas, petrochemicals and power and water treatment. Other well-known products within the same brand are the 84K SteamForm valves specifically used for applications in the power sector, the 31K rotary valves fitted with PFA lining for corrosive applications and the 78K and 18K Lincoln Log and 49K V Log for high-pressure-drop applications on control valves.
The 41K Series heavy-duty globe control valves are engineered to handle the most demanding process conditions. The balanced, cage-guided construction of 41K provides key advantages versus typical unbalanced designs, namely higher flow capacities, higher pressure drop capabilities, reduced actuator size and thrust requirements, improved stability with larger guide areas and increased low noise and anti-cavitation trip options.
41K's design offers versatile trim options including single-stage and multi-stage trims that provide low-noise performance and effective anti-cavitation solutions for liquid services. Other trim designs are pilot balanced trim for tight shutoff and variable resistance trim for cavitation on high-pressure drop. There are special trim designs for custom-made valves.
Under the Consolidated safety relief valve brand, the 1900 model enjoys strong demand in the oil and gas sector, the 1700 and 2700 models have specific boiler applications in the power sector and the 3900 pilot-operated valves are used in high backpressure and pressure-drop applications in all sectors.
While both brands have applications across a wide swathe of sectors, most of Darvico's sales come from the refinery and petrochemical industries.
EXPANSION AND SAUDISATION With purchase orders flowing in and more expected, Darvico is implementing an expansion programme that will see its plant expand by another 20,000 sq ft. The enlarged area will house a new and improved storage facility to accommodate additional valves and spares. This facility is an important addition as Darvico coordinates and supports end-users and EPC contractors' right from the Feed stage and holds inventories of valve bodies, bonnet castings, gaskets, O-ring kits and springs in line with its forecasts for both Masoneilan and Consolidated brands, enabling it to cut response time to the minimum. It estimates the value of its warehoused stock to be in excess of $10 million.
Also key to the company's appeal in the industrial sector is its after-market, repairs and service programme for which it mobilises test benches at customer sites for the latter's convenience. Two such test benches are being used to cover distant customers from Darvico's centralised offices in Jubail and Yanbu.
"Plant expansion work is in full swing and targeted for completion by the end of this year," said the spokesman.
The company also highlighted it accords high priority to Saudisation in pursuit of which it has been regularly training Saudis and creating job opportunities for them.
