Nuts, as a common fastener, are widely used in various fields and scenarios. The following are some of the main applications of nuts:

When the threads of a bolt and nut mate, a "helical slope" forms between the two components.

As the workhorse of industrial heating, flange heating elements are often damaged after a short period of use, impacting production and increasing cos

Flanges are common components in pipeline engineering. In pipeline construction, flanges are primarily used to connect pipes.

Flanges can be reused, but proper maintenance and judgment are required based on specific circumstances.

Many customers question whether welded flanges outperform forged welded flanges.

WCB (carbon steel), LCB (low temperature carbon steel), LC3 (3.5% nickel steel),

The flange diameter refers to the outer circular diameter of the flange and is a very important parameter when assembling flanges.

The nominal diameter is a standardized designation for the inside diameter of the pipe to which the flange connects, expressed in millimeters (mm).

Slip-on flange (SO flange): Requires only single-sided welding, low cost, but weak pressure bearing capacity (common pressure ≤ 2.5 MPa), mostly used

Flanges come in a variety of types, including butt-weld flanges, slip-on flanges, and lap-joint flanges.

The nominal diameter (DN) range is typically DN15-DN600, while the American standard corresponds to 1/2"-24" (ANSI B16.47).
