DIN1630 ST37.4 ST52.4 paipu kila pololei
ʻO DIN1630 St37.4 St52.4 kahi ʻano o ke kila kalapona i hoʻohana ʻia i nā ʻōnaehana hydraulic a me ka pneumatic.Ua ʻike ʻia no kāna kikoʻī kiʻekiʻe, ka hana maikaʻi loa, a me ka paʻa pono.

ʻO ka hōʻoia maikaʻi
1. Nānā Mea Makaʻu e komo mai ana
2. Hoʻokaʻawale ʻia nā mea maka e pale i ka hui ʻana o ke kila
3. Hoʻopau wela a hāmare no ke kaha kiʻi anu
4. Ke kaha ki'i anu a me ka holo anu, ma ka nana laina
5. Hoʻoponopono wela, +A, +SRA, +LC, +N, Q+T
6. Hoʻopololei-ʻoki i ka lōʻihi i hoʻopau ʻia i ke ana ʻana
7. Mechanical Testing in own labs with Tensile Strength, Yield Strength, Elongation, Hardness, Impact,
Microinstruction etc
8. Hoʻopili ʻana a me ka hoʻopaʻa ʻana
Palapala noi
Hoʻohana pinepine ʻia ka DIN1630 hydraulic steel tube i nā ʻōnaehana hydraulic a me nā pneumatic, e like me nā cylinders hydraulic, nā laina hydraulic, a me nā noi kiʻekiʻe.
Hoʻohana nui ʻia ia i nā ʻoihana e like me ka automotive, aerospace, kūkulu, a me nā mīkini, kahi i koʻikoʻi ai ka pololei a me ka hilinaʻi no ka hana ʻole.
Pūʻolo huahana
ʻO ew Gapower Metal ka mea hana ʻoihana o ka paipu kila hydraulic.
a me 20,000 tona pahu kila a me ka pahu wela.
