Hexagonal self-drilling screws, i hana ʻia e Hebei Wotu Fastener Manufacturing Co., Ltd., hana ma lalo o kahi ʻōnaehana ʻoihana hou a mālama pono e like me ka ISO9001: 2015 ʻōnaehana maikaʻi. Hoʻohana ka hui iā "Wotu" ma ke ʻano he inoa inoa inoa.
ʻO ka huaʻōlelo "mau ʻāpana maʻamau" ma Kina he pōkole no "nā mea hoʻopaʻa maʻamau," he wehewehe haiki. ʻO nā ʻāpana maʻamau kiʻekiʻe a me ka medium-pressure e pili ana i kahi ʻano paʻa i hiki ke kū i kekahi kaomi a hoʻohana ʻia i nā wahi kūikawā kūikawā. ʻO ka manaʻo o nā ʻāpana maʻamau kiʻekiʻe a me waena no nā rivets makapō. ʻO ka huaʻōlelo "mau ʻāpana maʻamau" ma Kina he pōkole no "nā mea hoʻopaʻa maʻamau," he wehewehe haiki. ʻO nā ʻāpana maʻamau kiʻekiʻe a me ka medium-pressure e pili ana i kahi ʻano paʻa i hiki ke kū i kekahi kaomi a hoʻohana ʻia i nā wahi kūikawā kūikawā.
ʻO ka manaʻo o nā ʻāpana maʻamau kiʻekiʻe a me waena no nā rivets makapō. Nā Kūlana a me nā māka no ka hoʻohana maʻamau ʻia ʻo High and Medium Pressure Drill Self-Drilling Screws
1. ASTM A193 / A193M-2009 "Alloy Steel a me Kuhiliʻole Steel Bolts no High Temperature Lako". He nui nā māka kēia maʻamau, ʻo nā mea maʻamau i hoʻohana ʻia: Gr.B6, B7, B7M, B8, B8M, B8-2, B8M-2, B16, etc.
2. ASTM A194 / A194M-2009 "Standard Specification for Nuts for High Temperature or High Pressure or High Temperature and High Pressure". He nui nā māka kēia maʻamau, ʻo nā mea maʻamau i hoʻohana ʻia: Gr.2H, 2HM, 4, 6, 7, 7M, 8, 8M, etc.
3. ASTM A320 / A320M-2008 "Alloy Steel Bolts no ka hoʻohana haʻahaʻa haʻahaʻa". He nui nā māka kēia maʻamau, ʻo nā mea maʻamau i hoʻohana ʻia: Gr.L7, L7M, B8, B8M, B8-2, B8M-2, etc. (345-827 MPa)”. Loaʻa nā māka maʻamau Gr.660A a me 660B.
5. ASTM A182/A182M-2007 "Forged or Rolled Alloy Steel and Stainless Steel Flanges, Forged Pipe Fittings, Valves, and Companies for High-Temperature Applications". Loaʻa nā māka hoʻopaʻa maʻamau F51, F53, a me F55.
6. HG / T20634-2009 "Nā mea hoʻopaʻa no nā Flanges Pipe Steel" (Class Series). Hoʻololi kēia maʻamau i ka mana 1997, me ka hoʻohui ʻana i nā mea hou nui e pili ana i nā maʻamau ASTM a i ʻole ASME, a me ka wehe ʻana i ka paukū ma nā studs ʻelua.
7. HG / T20613-2009 "Nā mea hoʻopaʻa no nā Flanges Pipe Steel" (PN Series). Hoʻololi kēia maʻamau i ka mana 1997 a hoʻokomo i nā hiʻohiʻona hou e pili ana i nā kūlana ASTM a i ʻole ASME.
8. Nā Kūlana Kūlana ASME. ʻO nā maʻamau ASME e kuhikuhi pinepine i nā kūlana ASTM, e hana ana i nā hoʻololi kūpono a i ʻole nā mea hoʻohui e hana i kahi pūʻulu o nā maʻamau e hoʻomaka ana me SA, e like me: ASME SA193/SA193M; ASME SA194/SA194M; ASME SA320/SA320, etc.
ʻO Hebei Wotu Fastener Manufacturing Co., Ltd., he mea hana i nā hexagonal self-drilling screws, me ka ʻoiaʻiʻo e hui pū me nā hoaaloha mai nā ʻano like ʻole o ke ola ma ka home a ma waho, e hana pū ana i ka lima e hana i kahi kenekulia hou.
