Forged pipe reinforcement
Thread Content
Are there any standards for forged pipes? How should the dimensions of forged pipes be chosen?
The dimensions of forged pipes are determined for strength calculations
Calculate it yourself. . Forged pipes can basically be any size. . Of course, the length may be limited
It is designed and determined independently to meet the specified thickness ratio of forged pipes to the cylinder body, fulfill the reinforcement requirements, ensure proper material matching, and have a rational structure.
The dimensions of forged pipes are determined based on calculations for reinforcement through openings; it is sufficient as long as they meet the standard requirements
Generally, flanges are used on the outside. Since reinforcement with forged pipes is required, the pressure is usually not low; therefore, WN flanges are chosen. As a result, the inner diameter is determined based on the dimensions of the flange, and it is the same as the inner diameter of the pipe flange. The outer diameter is determined based on the calculations required.
Forged pipes are not pipes that conform to any standard; they are made by processing forgings, so don’t take the literal meaning
Forged pipes are made from forgings, and there are no standards for them. The inner diameter of a forged pipe is taken as that of the flange to which it is connected, while the outer diameter must be determined through reinforcement calculations. Generally, the ratio of the wall thickness of a forged pipe to that of the cylinder body ranges from 0.5 to 2; it is best not to exceed this range. The portion beyond the range of pipe reinforcement must have its outer diameter altered to match that of the flange’s connection pipe through a conical section, to facilitate welding. The design of the conical section can draw on that of the WN-type flange, or it can be designed independently according to the relevant requirements of GB150 if necessary.
There was an HGJ527-90 standard for \"reinforcement pipes\" available for reference a long time ago, but now it is sufficient to carry out calculations for opening reinforcement according to GB/T150; using a 45-degree angle in the transition section can reduce the amount of work required. Make sure to leave enough length of straight edge when using SO flanges.
This is non-standard and determined based on calculations.
