What size of thread should be for the electric tubular heating elements?
Some customers do not know what is the size of the installation thread should be for the electric tubular heating elements when ordering the heating elements. The fastener is composed of fixed baffle, thread, washer, nut, porcelain head and terminal post. When the customer installs the electric tubular heating elements, they only need to drill a hole which is equal to or slightly larger than the screw thread diameter of the fastener, and then thread the fastener through the hole and screw it with the nut. The appearance of fasteners perfectly solves the problem of difficult installation of tubular heating elements and is easy to operate. The diameter of the opening is determined by the thread diameter of the fastener visible above. How large is the installation thread of the electric tubular heating elements?
The answer is the diameter of the electric tubular heating elements, and the diameter of the electric tubular heating elements is proportional to the thread diameter of the fastener. (the diameter of heating pipe is in mm, the thread diameter of fastener is expressed by mxx, and 1.5 refers to the pitch of thread)
When pipe diameter = 8mm, thread diameter of fastener = M14 * 1.5
When pipe diameter = 10mm, thread diameter of fastener = M16 * 1.5
When pipe diameter = 12mm, thread diameter of fastener = M18 * 1.5
When pipe diameter = 16mm, thread diameter of fastener = M22 * 1.5
When pipe diameter = 18mm, thread diameter of fastener = M24 * 1.5
When pipe diameter = 20mm, thread diameter of fastener = M27 * 1.5
When pipe diameter = 25mm, thread diameter of fastener = M30 * 1.5
From the above list, it can be seen that at first, the relationship between the thread diameter of the tubular heating elements' fastener and the pipe diameter is 6 parameters. Later, when the pipe diameter is 20 mm, the thread diameter of the fastener is M27 * 1.5, and when the pipe diameter is 25 mm, the thread diameter of the fastener is M30 * 1.5. These two are special relations. After mastering the above rules, we can judge the installation thread size of the electric tubular heating elements according to the diameter of the heating pipe, and then determine the diameter of the opening of the installation object.
