Chemical Composition and Mechanical Properties of LSAW Steel Pipe

LSAW Steel Pipe Manufacturing Process:

LSAW steel pipe (Longitudinally Submerged Arc Welding abbreviated as LSAW) is a professional expression term for LSAW steel pipe. It uses a single medium and thick plate as the raw material, and the steel plate is pressed (rolled) into a tube blank in a mold or a forming machine. The pipe is produced by submerged arc welding and expanded diameter.

UOE LSAW turbany emele getirmek prosesi:
UOE LSAW polat turbany emele getirmegiň üç esasy emele getiriş prosesi: polat plastinka öňünden egilmek, U emele getirmek we O emele getirmek. Her bir proses polat plastinkanyň tegelek turbasyna deformasiýa edilmegi üçin yzygiderli polat plastinanyň gyrasyny, U emele getirýän we O emele getirýän üç prosesi tamamlamak üçin ýörite emele getiriji metbugat kabul edýär.

JCOE LSAW pipe forming process:
Forming: After several steps of stamping on the JCO forming machine, first half of the steel plate is pressed into a "J" shape, then the other half of the steel plate is pressed into a "J" to form a "C" shape, and finally pressurized from the middle to form An open "O"-shaped tube blank is formed.

LSAW polat turbasynyň daşalmagy
When transporting, loading and unloading lsaw welded pipes, special hoisting and transportation tools should be used to avoid scratching the surface.

Production equipment of LSAW steel pipe

Plastinka gyrasy degirmen
Freze maşyn, ini, gyrasy we çukur görnüşiniň aýratynlyklaryna laýyk gelmek üçin tabagyň iki tarapyny takyk standartlara üweýär.

Gyrasy gysýan maşyn
Gyrgyç maşyn gerekli egriligi emele getirmek üçin tabagyň gyralaryny gysýar.

Kebşirleýiş enjamy
Açyk tikiş turbasynyň iki gyrasy kebşirleýji maşyn bilen birleşdirilýär. soňra demir işjeň - gaz arkasy kebşirlemek ("MAG") prosesi bilen kebşirleýji bilen kebşirlenýär.

Dörediji maşyn
Egilen we polat turbany polat turba öwürmek üçin "JCO" amalyny ulanýar.

Içki kebşirleýji maşyn
Turbanyň içki uzyn boýy, turbany herekete getirende we suwasty ýaýly kebşirleýiş amalyny ulanyp, 4 kebşirleýiş kellesini düzedip, içinden kebşirlenýär.

Ahyrky maşyn
Enjam, zerur çukuryň we gyranyň aýratynlyklarynyň ýerine ýetirilmegini üpjün etmek üçin turbanyň ujuny aýlanýan kesiji kelleler bilen deňleşdirýär.

Gidrostatik synagçy
Endüzüň möhürleme tehnologiýasyny ulanmak, gidrostatik synag wagtynda kör zolaklary ýok edýär. Synag, şeýle hem awtomatiki ýazgy we saklamak funksiýalary bilen enjamlaşdyrylandyr.

Giňeldýän maşyn
Turbanyň ölçegleriniň takyklygyny ýokarlandyrmak we içerki stres paýlanyşyny gowulandyrmak üçin turba doly uzynlyga sezewar edilýär.
