SPiral welded karfe bututu

Karkace welded karfe bututu kuma aka sani da karkace karfe bututu da karkace welded bututu, wanda aka yi amfani da low carbon tsarin karfe ko low gami karfe tsiri bisa ga kwana na karkace line (wanda ake kira forming kwana) birgima a cikin wani tube, sa'an nan. da bututu welded tare sanya, zai iya zama kunkuntar tsiri samar da manyan diamita karfe bututu.Ana amfani da coil ɗin don bututun mai da iskar gas, ƙayyadaddun sa OD * kauri na bango.Side waldi da biyu-gefe waldi karkace welded bututu kamata tabbatar da cewa hydrostatic gwajin, da tensile ƙarfi na weld da sanyi lankwasawa yi da ake bukata.

(1) da matsa lamba ruwa watsa karkace submerged baka welded bututu: yafi amfani da sufurin mai, na halitta bututun iskar gas;

(2) da matsa lamba ruwa watsa high mita welded karfe bututu tare da karkace kabu: welded high-mita cinya waldi hanya domin matsa lamba ruwa watsa karkace high-mita welded karfe bututu.Damar bututun ƙarfe a ƙarƙashin matsin lamba, filastik mai kyau, sauƙin waldawa da tsarin gyare-gyare;

(3) low matsa lamba ruwa watsa karkace submerged baka welded karfe bututu: biyu-gefe atomatik submerged baka waldi ko guda-gefe waldi a cikin doka tsarin ga low matsa lamba ruwa kamar ruwa, gas, iska da tururi tare da submerged baka welded bututu.

Halayen samfuran bututu mara kyau:
1. sumul tube tsari gwajin yi: flattening gwajin, tensile gwajin, tasiri gwajin, flaring gwajin, taurin gwajin, metallographic gwajin, lankwasawa gwajin, nodestructive gwajin (ciki har da eddy halin yanzu X-ray da ultrasonic gwaji).

2.Seamless binciken sinadarai na bututu: abubuwan da ke tattare da sinadarai na kayan aiki don nazarin sinadarai, abubuwan sinadaran don saduwa da daidaitattun buƙatun.

3.Seamless bututu matsa lamba da hydrostatic gwajin ne ga matsa lamba tube ta cikin hydrostatic gwajin, wanda ba su kula da matsa lamba darajar ba kasa da 5 seconds, ba don bayyana, na yau da kullum samar da na'ura mai aiki da karfin ruwa gwajin gwajin ne 2.45MPa matsa lamba gwajin matsa lamba ne. P = 0.5MPAa.

4.The lalata gwajin: masana'antu lalata-resistant karfe bututu bisa ga misali ka'idoji ko yarjejeniya tsakanin lalata karfe bututu lalata juriya gwajin, babu intergranular lalata.

Halayen bututu maras kyau
(1) diamita na waje ya fi karami.

(2) Babban madaidaici na iya yin ɗanɗano kaɗan na ɗanyen.

(3) sanyi kõma karfe bututu da high daidaici da kyau surface quality.

(4) karfe bututu giciye yankin ne mafi hadaddun.

(5) karfe bututu mafi girma yi, in mun gwada da m karfe.
