ASTM A53 čelične cevi designations are different than ASTM A500 round hollow structural sections and they are manufactured to meet different standards. Dok ASTM A500 dostupna je u cross-sections koje se podudaraju sa svakog od cross-sections za ASTM A53steel lula, Nema dostupnih mnogo više cross-sections u A500.
Karakteristike i aplikacije od ASTM A500 čelične cevi:
A500 čelične cevi mogu biti stavljeni pod veliki deo uobičajeni fabrikuje operacija. Provodljivost je dobro. Pa tako je zakrivljen., u zastoju, smanjenja, udarce, signalne rakete i ANKERI lako, i mogu zavariti obično koristi tehnike i practices.Common koristi za ASTM A500 cev uključuju suvenirima, objavljene poruke, storage racks, displays, furniture, Structural applications, Bollards, Micro-piling.
ASTM A500 applications include structural supports, building columns, highway signs, oil field services and communication towers, да поменемо само неке. All steel structures have their pros and cons, but ultimately ASTM A500 is the better choice when you need a round profile.
Characteristics and Applications of ASTM A53 челичне цеви :
Designed for coiling, savijanje i flanging, A53 karbonski lulu pogodan je za zavarivanje. The grades denote certain chemical and mechanical properties and should be noted in selection.A53 pipe is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, voda, gas i vazduh linije, Low pressure systems, Structural applications, Mechanical components, Bollards, Kućište
ASTM A500 is a structural specification, round HSS produced to this specification are fit for purpose when used for structural applications and general construction use. ASTM A53 is a pipe specification and is intended to be used in mechanical and pressure applications.
The specified yield strength of A500 Grade C (the most commonly available grade) је 46 knjizi. The specified yield strength of A53 Grade B is 35 knjizi. That’s over a 30% increase in yield strength. Zbog toga, A500 round HSS have greater strength-to-weight ratios than A53 pipes. Tako, with round HSS you need less steel, према тежини, to do the job—less weight equals less cost.
ASTM A53 PIPE TYPES
The following types & grades of A53 pipe are covered within this specification:
Type F – Furnace-butt-welded, continuous welded Grade A
Type E- Electric-resistance-welded, Ocene A i B
Type S- Bešavne, Ocene A i B
