SA-213 T91 Seamless Steel Pipe
T91 is a temperatura għolja liga azzar komunement użat in qawwa pjanti u oħrajn industrijali applikazzjonijiet fejn temperatura għolja u pressjoni għolja kundizzjonijiet jeżistu. It fih elementi bħal kromju, molibdenu, u vanadju, li jipprovdi eċċellenti temperatura għolja strength, korrużjoni reżistenza, u creep resistance. It spiss jintuża fwar boilers, superheaters and heat exchangers li joperaw fi għoli temperaturi.
SA-213 T91 Seamless Steel Pipe
SA-213 T91 is a specific grade of seamless ferritic and austenitic steel boiler, superheater and heat exchanger tubes known for tagħhom excellent high temperature performance.

Product Process
Materja mhux ipproċessata Materja Għażla : Il-proċess jibda bi attent għażla ta ' materja prima materjali. Għoli kwalità billets jew ingotti huma magħżula ibbażati fuq tagħhom kimika kompożizzjoni biex jiżguraw huma jissodisfaw l- stringent speċifikazzjonijiet meħtieġa għal SA-213 T91 stainless azzar.
Tisħin għal Form: The selected raw materials are heated to the proper temperature for forming. This may involve processes such as hot extrusion or piercing to create hollow tubes. The heated material is then pierced through the mandrel to form a cylindrical shape.
Rotary piercing: In this method, a a rotary piercing machine is used to punch holes in the heated billet. As the billet rotati, it is pierced by tapered rollers li gradwalment żieda id-dijametru ta' it the hole.
Hollow Shell Fabrication: A series of rolls and dies are used to elongate and shape the perforated blank. This process helps create a hollow shell with the desired outside diameter (OD) and wall thickness.
Daqs u Tnaqqis : Addizzjonali rombli u dies huma użati biex aktar elongate u reduce id-daqs ta ' il vojt qoxra. Dan pass jiżgura preċiż dimensjonijiet u itejjeb il-wiċċ finitura ta ' il- pajp .
Sħana Trattament : Sħana trattament huwa a ċavetta pass in titjib il - mekkaniku proprjetajiet ta ' il- materjal . Pajpijiet huma imsaħħna għal a speċifiku temperatura u imbagħad malajr imkessaħ metodi tali bħal estinzjoni u ittemprar. Dan il-proċess jagħti l-aħħar prodott saħħa , ebusija u reżistenza.
Kiesaħ Tpinġija: Il pajp huwa miġbud permezz a serje ta ' dies fil kamra temperatura għal reduce tagħha dijametru u ħajt ħxuna. Dan kiesaħ tpinġija proċess itejjeb il - dimensjonali eżattezza " 2c wiċċ finitura u mekkanika proprjetajiet ta ' il- ... il-pajp .
Ittemprar: The pipe is annealed in order to remove internal stresses and improve the processability of the pipe. The pipe is heated and then slowly cooled to improvetype and reduce ebusija.
Finali Sizing and Finishing: The pipe is again passed through a sizing die to achieve the exact dimensions required by the SA-213 T91 specification. The surface can be further treated to achievein the desired finish.
Ittestjar u Kwalità Kontroll : Rigoruż ittestjar huwa mwettaq biex jiżgura li il- il-pajp jissodisfa l- standards meħtieġa Dan jinkludi testijiet għal kimika kompożizzjoni , mekkaniku proprjetajiet , ebusija, idrostatiku pressjoni , u aktar.
Finali Spezzjoni u Ippakkjar: Wara il- pajp passes il kwalità kontroll testijiet, it undergoes a finali viżwali spezzjoni. Huwa imbagħad bir-reqqa ippakkjat biex tipproteġi it matul trasport u ħażna.
