Amapayipi ensimbi ahlukaniswe abe amapayipi ensimbi angenamthungo namapayipi ensimbi ashiselwe (amapayipi athungelwe).

I-boiler tube iwuhlobo lweshubhu engenamthungo. Indlela yokukhiqiza iyafana neyepayipi elingenamthungo, kodwa kunezidingo eziqinile kumabanga ensimbi asetshenziselwa ukukhiqiza amapayipi ensimbi. Ngokusho kwezinga lokushisa lokusetshenziswa, lingahlukaniswa ngamashubhu abhayela ajwayelekile kanye namashubhu abhayela anomfutho ophezulu.

1) Amamaki ensimbi ensimbi yekhwalithi ephezulu ye-carbon structural yi-20G, 20MnG kanye ne-25MnG.

2) I-alloy structural steel amabanga 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, njll.

Amashubhu Ensimbi Angenamthungo Wamabhola Okucindezela Okuphansi Naphakathi (I-GB3087-2008), Amashubhu Ensimbi Angenamthungo Wamabhoyela Okucindezela Okuphezulu (I-GB5310-2008), I-ASME SA-106, I-ASME SA-213, I-ASTM A335

Ngaphezu kwalokho, inkampani yethu futhi isebenza ngamapayipi ensimbi angenamthungo ezinhlakeni (I-GB/T 81628163), amapayipi ensimbi angenamthungo wokuqhekeka kwe-petroleum (GB9948), amapayipi ensimbi angenamthungo omanyolo onengcindezi ephezulu (GB6479), amapayipi kawoyela (I-API 5L) namapayipi okufaka uwoyela (I-API 5CT), kanye nokufakwa kwepayipi lengxubevange.
