On-Site Repair Possible by Iran-Made Oil Valves
“This type of ball valve, which is being manufactured by a domestic manufacturer with experience in the oil and gas industry, provides the operator with the capability to repair on-site without the need to disconnect the valve from the pipeline in a completely optimal way,” said Nasrollah Zareyee, the managing director of the company.
He added that the achievement has saved the country three million of dollars in oil industry.
“We hope that by utilizing the capacities of domestic manufacturers and knowledge-based companies as much as possible, we will be able to complete the development of projects more quickly,” Zareyee said.
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.”
