Bend pipe is curved using the progress of complete bending apparatus, is divided into cold stewing with picking two kinds of techniques.It is either any
Machinery equipment and pipeline, it is most of all to use bend pipe, mainly to oil transportation, gas transmission, infusion, engineering bridge construction etc..Pure bending
When, pipe its neutral line outer webs wall tension stress under outer moment M effects is acted on and is thinned, inside compression chord.Effect
And thicken, the N1 and N2 that makes a concerted effort makes pipe cross section change.Based on this factor, bending quality is caused to decline main cause be
RX and SX so, in GBJ235-82, the RX values in the case of various pressure ratings and the Reducing thickness in outside have been done clearly
Regulation, in order to the value of RX and SX are controlled, so that it is guaranteed that quality.Outer material side tension during bend pipe, inside compression neutral axis
