Iranian Refineries Equipped with Home-Made Steam Reduction Valves
“Since two years ago, the 8th South Pars Refinery has invited us to cooperate to help and provide a solution regarding the production of steam reduction unit valves,” said Mohammad Reza Sinayee, the managing director of the knowledge-based company.
“These valves are a more advanced model, gate valves that have 100% sealing activity. The entire technical know-how of Troconduit valves exists in our company and we have for the first time in the world designed and produced them at a temperature of 280 degrees and a pressure difference of 40 bars,” he added.
“These valves are produced in two models of double disc and parallel disc, the double disc model of which is used in gas refineries,” Sinayee said.
In a relevant development in August, researchers at an Iranian knowledge-based company 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.”
