Rough-Turned Mechanical Tubing—Ang pagkakaiba-iba sa labas ng diameter at kapal ng pader ay hindi dapat lumampas sa tolerance sa Table. Sinasaklaw ng talahanayan ang mga pagpapaubaya gaya ng inilapat sa panlabas na diameter at kapal ng pader at nalalapat sa tinukoy na laki.
Ground Mechanical Tubing—Ang pagkakaiba-iba sa labas ng diameter ay hindi lalampas sa mga tolerance sa Talahanayan. Ang produktong ito ay karaniwang ginagawa mula sa isang malamig na tubo.
Mga Haba—Ang mekanikal na tubing ay karaniwang ibinibigay sa haba ng gilingan, 5 piye (1.5 m) at higit pa. Ang mga tiyak na haba ng hiwa ay ibinibigay kapag tinukoy ng bumibili. Ang mga pagpapaubaya sa haba ay ipinapakita sa Talahanayan.
Straightness—Ang straightness tolerances para sa seamless round tubing ay hindi lalampas sa mga halagang ipinapakita sa Table.
Kinakailangan sa Pagsusulit
1. Hardness Test
Kapag kinakailangan ang mga limitasyon sa katigasan, dapat kumonsulta sa tagagawa. Ang mga tipikal na katigasan ay nakalista sa Talahanayan . Kapag tinukoy, ang hardness test ay isasagawa sa 1 % ng mga tubo.
2. Mga Pagsusuri sa Pag-igting
Kapag kinakailangan ang mga katangian ng makunat, dapat kumonsulta sa tagagawa. Nakalista sa talahanayan ang mga tipikal na katangian ng tensile para sa ilan sa mga mas karaniwang grade at thermal condition.
3.Hindi Mapanirang Pagsusulit
Available ang iba't ibang uri ng nondestructive ultrasonic o electromagnetic test. Ang pagsubok na gagamitin at ang mga limitasyon sa inspeksyon ay dapat itatag ng kasunduan ng tagagawa at mamimili.
4.Flaring Test
Kapag may mga espesyal na kinakailangan para sa kalinisan ng bakal, ang mga pamamaraan ng pagsubok at mga limitasyon ng pagtanggap ay dapat itatag ng kasunduan ng tagagawa at mamimili.
