Beth yw'r JIS G 3466 ?
JIS G3466mae'r safon hon yn ymdrin yn benodol â hitiwbiau dur carbon at ddibenion strwythurol cyffredinolsydd fel arfer yn cael eu ffurfio gan-broses ffurfio oer ac o ganlyniad weldio gwrthiant trydan (ERW). Mae'r adrannau hyn yn cael eu cyflenwi fel-cyflwr rholio heb driniaeth wres oni nodir yn wahanol.
Nodiadau: Mae safon JIS G3466 yn Safon Ddiwydiannol Japaneaidd sy'n nodi'r gofynion ar gyfer dur carbontiwbiau sgwâr a hirsgwara fwriedir at ddibenion strwythurol cyffredinol.
Dynodiad

1. Pan fydd y tiwb o dan 8 mm o drwch yn destun prawf tynnol, rhaid cyfrifo isafswm gwerth elongation trwy dynnu 1.5% o werth yr elongation a roddir yn Nhabl 3-2 ar gyfer pob gostyngiad o 1 mm a thalgrynnu'r canlyniad i rif cyfan yn ôl JIS Z 8401.
2. Pan fydd darn prawf tynnol i'w gymryd o'r tiwb sgwâr dur wedi'i weldio, rhaid cymryd un o ddogn di-dor. |

Dimensiynau, Goddefiannau Màs a Dimensiwn
Goddefgarwch Ar Dimensiwn a Phwysau
Rhaid i ddimensiynau a màs y tiwbiau sgwâr fod fel y nodir yn y Tabl Atodi. Fodd bynnag, bydd radiws safonol crymedd yn y gornel yn 1.5 o drwch wal ar linell ganol trwch y wal.
Goddefiannau Dimensiynol
Bydd y goddefiannau ar hyd ochr, anwastadrwydd cyfran plât gwastad ar gyfer pob ochr, onglogrwydd a wneir rhwng dognau plât gwastad cyfagos, dimensiwn ar gornel, hyd, ansythrwydd a thrwch wal ar gyfer tiwbiau sgwâr fel y nodir yn Nhabl. Yn yr achos hwn, rhaid mesur dimensiynau'r proffil adrannol a'r ongl yn y gornel ar unrhyw bwynt ac eithrio dau ben y tiwb sgwâr.
| Eitem a dimensiwn penodol | Goddefiannau dimensiwn | ||
| Hyd yr ochr | Llai na neu'n hafal i 100 mm | ±1.5mm | |
| >100 mm | ±1.5% | ||
| Anwastadrwydd plât gwastad rhan o bob ochr |
Hyd ochr Llai na neu'n hafal i 100 mm | 0.5 mm ar y mwyaf | |
| Side length >100 mm | O fewn 0.5% o hyd yr ochr | ||
| Anguiiarity a wneir gan ddognau plât gwastad adfacent | ±1.5% | ||
| Dimensiwn yn y gornel:s | 3mm ar y mwyaf | ||
| Hyd | +ddim yn benodol 0 | ||
| Ansythineb | O fewn 0.3% o hyd yr ochr | ||
| Trwch wal | Tiwb dur sgwâr a weithgynhyrchir gan weldio | <3mm | ±0.3mm |
| Yn fwy na neu'n hafal i 3mm | ±10% | ||
| Tiwb dur sgwâr di-dor | <4mm | ±0.6mm | |
| Yn fwy na neu'n hafal i 4mm | ±15% | ||
Nodiadau:
1. Diffinnir y "rhan plât gwastad" fel y gyfran deor a ddangosir yn y ffigur isod.
2. Gellir newid y goddefiannau ar y dimensiynau yn y gornel trwy gytundeb rhwng y prynwr a'r gwneuthurwr.
3. Rhaid cymhwyso'r goddefiannau ar ansythrwydd ar y tro uchaf i'r tro isaf a'r troad o'r dde i'r chwith gyda thraw hir.
4. Rhaid cymhwyso'r goddefiannau ar drwch wal i'r gyfran plât gwastad.
