一 . klasifikasyon pa metòd pwodiksyon
Tiyo asye ka divize an de kategori dapre metòd pwodiksyon: tiyo asye san pwoblèm ak tiyo asye soude .
1. tiyo asye san pwoblèm ka divize an tiyo cho-woule san pwoblèm, tiyo frèt-trase, tiyo asye presizyon, tiyo cho-elaji, tiyo frèt-file ak tiyo èkstrude dapre metòd pwodiksyon .}
Tiyo asye san pwoblèm yo te fè nan-wo kalite asye kabòn oswa asye alyaj ak yo divize an cho-woule ak frèt-woule (trase) .
2. Welded steel pipes are divided into furnace welded pipes, electric welded (resistance welded) pipes and automatic arc welded pipes due to their different welding processes. They are divided into straight seam welded pipes and spiral welded pipes due to their different welding forms. They are divided into round tiyo soude ak espesyal ki gen fòm (kare, plat, elatriye .) soude tiyo akòz fòm fen yo .
Welded steel pipes are made of steel plates rolled into a tube shape by welding with butt seams or spiral seams. In terms of manufacturing methods, they are divided into welded steel pipes for low-pressure fluid transportation, spiral seam electric welded steel pipes, direct rolled steel pipes, electric welded pipes, etc. Seamless steel Tiyo yo ka itilize pou divès kalite likid ak tiyo gaz . tiyo soude ka itilize pou tiyo dlo, tiyo gaz, tiyo chofaj, elatriye .
2. klasifikasyon pa materyèl
Tiyo asye ka divize an tiyo kabòn, tiyo alyaj, tiyo asye pur, elatriye . dapre materyèl la (mwen . e . kalite asye) nan tiyo a .}
Tiyo kabòn yo ka divize an tiyo òdinè kabòn asye ak kalite siperyè kabòn tiyo estriktirèl .
Alloy pipes can be divided into low alloy pipes, alloy structural pipes, high alloy pipes, and high-strength pipes. Bearing pipes, heat-resistant and acid-resistant stainless pipes, precision alloy (such as Kovar) pipes, and high-temperature alloy pipes.
3. klasifikasyon pa metòd koneksyon
Tiyo asye ka divize an tiyo plenn (san yo pa fil nan tiyo yo fini) ak tiyo Threaded (ak fil nan tiyo yo fini) dapre metòd la koneksyon nan tiyo a fini .
Tiyo Threaded ka divize an tiyo òdinè Threaded ak epè tiyo Threaded nan tiyo a fini .
Epesi tiyo Threaded kapab tou divize an tiyo Threaded ak epesman ekstèn (ak fil ekstèn), epesman entèn (ak fil entèn), ak epesman entèn ak ekstèn (ak fil entèn ak ekstèn) .
Tiyo Threaded kapab tou divize an tiyo fil ak fil komen silendrik oswa konik ak fil espesyal dapre kalite fil .
Anplis de sa, tiyo Threaded yo jeneralman lage ak jwenti tiyo dapre bezwen itilizatè .
4. Klasifikasyon pa karakteristik kouch
Tiyo asye ka divize an tiyo nwa (ki pa kouvri) ak tiyo kouvwi dapre karakteristik kouch sifas .
Tiyo kouvwi gen ladan tiyo galvanised, tiyo aliminyòm-kouvwi, chrome-kouvwi tiyo, tiyo aliminyòm-difize ak lòt tiyo alyaj-kouch asye .
Tiyo kouvwi gen ladan tiyo kouch eksteryè, tiyo kouch enteryè, ak enteryè ak tiyo kouch ekstèn {{0}
5. klasifikasyon pa itilize
1. tiyo pou tiyo . tankou: tiyo san pwoblèm pou dlo, tiyo gaz, tiyo vapè, tiyo lwil, ak tiyo lwil oliv ak gaz kòf {{2}
2. Pipes for thermal equipment. Such as boiling water pipes and superheated steam pipes for general boilers, superheated pipes, large smoke pipes, small smoke pipes, arched brick pipes and high-temperature and high-pressure boiler pipes for locomotive boilers, etc.
3. Pipes for the machinery industry. Such as aviation structural pipes (round pipes, oval pipes, flat oval pipes), automobile half-axle pipes, axle pipes, automobile tractor structural pipes, tractor oil cooler pipes, square pipes and rectangular pipes for agricultural machinery, transformer pipes and bearing tiyo, elatriye .
4. Pipes for petroleum geological drilling. Such as: oil drilling pipes, oil drill rods (square drill rods and hexagonal drill rods), drill braces, oil oil pipes, oil casings and various pipe joints, geological drilling pipes (core pipes, casings, active drill rods, drill braces, clamps and pin joints, elatriye .) .
5. tiyo pou endistri chimik la . tankou: lwil fann tiyo, tiyo pou echanjeur chalè ak tuya
6. tiyo pou lòt depatman . tankou: tib pou resipyan (tib pou silenn gaz presyon ak tib veso jeneral), tib pou enstriman ak ekipman, tib pou gade ka yo, tib pou zegwi piki ak lòt aparèy medikal, elatriye.}
