Analysis and Application of Mathematical Model for Drawn Tee and Pipeline Opening Reinforcement

摘要: 介紹拔制三通和管線開孔的補(bǔ)強(qiáng)方法，分析拔制三通和管線開孔補(bǔ)強(qiáng)的數(shù)學(xué)模型，并應(yīng)用該數(shù)學(xué)模型進(jìn)行計(jì)算。分析認(rèn)為：在已知現(xiàn)場(chǎng)需求的條件下（設(shè)計(jì)壓力，三通主管外徑，支管外徑、鋼級(jí)），通過拔制三通和管線開孔補(bǔ)強(qiáng)的數(shù)學(xué)模型可以快速求出三通的設(shè)計(jì)壁厚；在已知設(shè)計(jì)壁厚情況下，將已知參數(shù)代入拔制三通和管線開孔補(bǔ)強(qiáng)的數(shù)學(xué)模型，可以反推出三通的產(chǎn)品試驗(yàn)壓力，簡(jiǎn)單快捷。

Abstract: Described here in the paper is the method for reinforcement of opening of the drawn tee and pipeline.Anal- yzed is the mathematic model for the said reinforcement.This model is used for relevant calculation.Based on the analysis result,it is identified that under given site-required conditions(i.e.the designed pressure,main ODand branch OD of the tee,and the steel grade),it is possible to use the said model to quickly calculate the designed wall thickness of the tee product,and moreover,with given designed wall thickness,it is also possible to reverse out the test pressure of the tee product by means of substituting the known parameters into the mathematic model.
