Iranian Experts Produce Advanced Control Valves for Oil Industry
A new technology-based firm (NTBF), backed by Arvand Petrochemical Company, has accomplished the design and production of the state-of-the-art control valves.
The entire process, from design to manufacturing, is based on the international standards and strict quality control principles.
The product plays a critical role in pressure reduction processes and the conversion of superheated steam to medium-pressure steam in the oil, gas, and petrochemical sectors.
The manufacturing process included various functional tests conducted at reputable domestic laboratories.
In a relevant development in August, researchers at an Iranian knowledge-based company had also succeeded in producing 32 gate valves needed in oil industry.
“We are a manufacturer of all kinds of valves needed by the oil, gas and petrochemical industries. The latest achievement of our company has been production of as many as 32 units of 20-inch gate valves of class 2,500 which have been used in development plan of Isfahan Oil Refinery. The achievement is considered as one of the largest valve-production projects of the oil companies in Iran,” Massoud Jalali, a representative of the knowledge-based company, told ANA.
Noting that valves are produced by using the open mold forging method due to the type of their structure, he said, “Open mold forging is a hot forming process in which metal is formed by hammering and pressing between flat or simple molds.”
“Gate valves are installed at the outlet of the distillery tower and are used to cut off and connect the flow. Also, the operation of these devices takes place at a temperature of 400 degrees (Fahrenheit) and 250 (Bar) of pressure; therefore, we should use heat-resistant materials in its construction,” Jalali said.
He explained that stainless steel materials should be used in metallurgy, saying, “This material is one of the most basic elements of gate valves and makes the valves resistant to heat.”
