Maximum diameter of steel-lined PTFE equipment

The diameter of steel-lined PTFE equipment mainly depends on production and installation techniques. Indeed, the standard HG20536-1993 \"Equipment with PTFE Lining\" specifies that the maximum equipment diameter is 2 meters. This value is not necessarily the absolute upper limit for the device diameter, but it was likely determined at the time the standard was established by taking into account factors such as the prevailing technologies of that period, device stability, and safety. If it is necessary to manufacture PTFE-lined steel equipment with a diameter greater than 2 meters, it may be required to find or establish corresponding specifications and standards, or to seek manufacturers with sufficient experience and expertise to carry out the customization. Furthermore, for large-diameter equipment, more experience and technical support are required for its design, fabrication, and installation. During the design and manufacturing process, special attention must be paid to issues such as the strength, stability, and safety of the equipment. Therefore, if it is necessary to manufacture PTFE-lined steel equipment with a diameter greater than 2 meters, it is recommended to consult a professional designer or manufacturer. .

Then it falls into the category of non-standard products – they are not manufactured in accordance with the established uniform industry standards and specifications, but are designed and produced according to an individual’s specific needs. It’s best to consult relevant manufacturers for more information
