HYDRAULICUS test
Expertus hydraulicus pro ferro tibiis singillatim peragendis. Maxime test pressio XX MPa est. Sub pressione experimenti, tempus stabilizationis non minus quam 10 s erit, et lacus ferreae fistulae non permittitur.
test adulatione
Experimentum adulationis agetur pro fistula ferrea cum diametro exteriore major quam 22 mm
Flaring test
Princeps qualitas chalybis carbonis structuralis et incorrupta (calor-repugnans) fistulae ferreae cum diametro exteriore non plus 76 mm et parietis crassitie non plus quam 8 mm sub experimento dilatandi erit. Expertus flagrans in cella temperies exercebitur. Diameter exterior ratis specimen elatans post summum nucleum cereum 60% of flaminium occurret requisitis mensae 7. Nulla rimas vel rimas in specimen post urentem concessum est. Secundum exigentias postulatoris et in contractu notatis, stannum structurale ferrum etiam adhiberi potest ad probationem dilatationem.
Nondestructive teste
Fistulae ferreae vitio detectioni ultrasonicae subicientur singillatim secundum praescripta GB / T 5777-2008. Secundum exigentias postulatoris, aliae probationes non perniciales addi possunt post tractatum inter supplementum et postulatorem et in contractu indicatis.
Erugo test
Testa corrosio intergranuaria agetur ad fistulam chalybem immaculatam (calor repugnans). Methodus probandi erit secundum praescripta methodi Sinensis E in GB/T 4334-2008, et corrosio intergranulare proclivitas post experimentum non licet.
Post tractatum inter supplicem et postulatorem, et notatis in contractu, postulator potest alias methodos testium corrosionis designare.
Oleum petrochemicum, pressura alta boiler, usus specialis tubo inconsutilem boiler inconsutilem, tubo geologico seamless ferro tubo et tubo olei inconsutilem.
