According to customer’s demanded material to produce the round bar,
then making annealled heat treatment, then drill the hole as
customer demanded inner diameter into the round bar, round bar
piercing, making rough hole, then make precision processing to make
outer diameter and inner diameter as requested. Any size hollow bar
can be produced as demanded.
Tolerance for hollow round bar, forged round bar drilling hole
hollow bar ASME SA530
| Type | Outer diameter(inner diameter) | Allowed tolerance | Wall thickness allowed tolerance |
Outer diameter | ≥219-457.2mm | -0.8 - +2.4mm |
-0.8 - +4.0mm |
| >457.2-660.4mm | -0.8 - +3.2mm |
| >660.4-863.6mm | -0.8 - +4.0mm |
| >863.6mm | -0.8 - +4.8mm |
| Inner diameter | All size | -1.6- 0mm | 0 - +3.2mm |
length tolerance -0 - +50mm
Round bar making Hollow bar cost is high
2. Hot rolled Hollow Bar
using hot rolled steel pipe billet to make heating and piercing,
elongating, sizing and stranghtening, cooling, finally hollow bars
finished, this is the type most commonly used. Because it is hot
rolled, so cost is lowest, but it is suit for large quantity, for
small quantity, have to make cold drawn or round bar piercing.
size: outer diameter 32mm- 499mm, wall thickness 4mm- 80mm
3. Cold drawn Hollow Bar
for outer diameter not over than 63.5mm, small size hollow bar,
when demanded quantity is under 5 tons, usually make cold drawn
hollow bar, using larger size hot rolled hollow bar to draw to the
size demanded.
some size can be finished only by one time drawing, but some other
sizes might need twice or three times to finish drawing, it takes
time, so the cost is higher.
cold drawn size outer diameter 32mm- 63.5mm
4. Hot- expanding Hollow Bar
For hollow bar sizes are special, not common sizes, have to use
smaller thick wall hollow bar to hot expand to be larger size
hollow bar, but the technical property for hot-expanded hollow bar
will be lower than the original hollow bar. Size: outer diameter
over 356mm.
