How to connect pipelines heated by thermal oil
Thread Content
Thermal oil heating is often used in the molding of polymer materials. What method is used to connect heating equipment and production equipment in general? Is it a flange connection or a threaded connection? What standards should be adopted, the national standard, the American standard, and the British standard?
Flange connection, generally follows American standards
Use flange connections greater than 2.5Mpa. Select according to the required specifications in the HG20592-20614 standard, and the flange, gasket, and fastener selection tables comply with the European system.
Thermal oil pipelines are connected by flanges. It doesn't matter whether the flanges are national standards or American standards. The equipment interfaces of domestic thermal oil manufacturers use national standards. The pressure of thermal oil when in use is generally only 0.3--0.4Mpa. The flange grade can be the commonly used 1.6Mpa. There is no need to use 2.5Mpa. RF raised face flanges can be used. Note that the permeability of thermal oil is strong, and the gasket must be a metal wound pad. Rubber asbestos pads or PTFE pads cannot be used.
