stainless steel welded/seamless tube 304

1,Size accuracy

The outside path admission deviation that solder take care of includes the elliptical park a cent Ⅰ , Ⅱ two class, see the table 3, table 4.

ⅠOutside path in class deviation mm table 3

Outside path inⅡ class deviation mm table 4

Outside path	Admission deviation
<25	±0.10
≥25~38.1	±0.15
>38.1~50	±0.20
≥50~63.5	0.25
>63.5~76	±0.30
≥76~102	±0.40

Outside path	Admission deviation
≤10	±0.15
>10~32	±0.20
>32~50	±0.30
>50	±0.8%

The thick the deviation of admission( do not include the weld sew) in wall of the weld tube is for ruling the wall thick 10% of ±, but minimum admission deviation is the 0.02 mms of ±.
The weld takes care of of settle Chinese foot length as 3 ms~9 ms, general settle the Chinese foot with the 6 ms.

The weld takes care of of settle the Chinese foot length in usually length, its the deviation of admission is the 5 mms of ±.
Adopt partial the degree of flinch in a the tube of weldfor keeping the Chinese foot measurement should not very in 2.0 mms.

FAQ

Small quantity, short time delivery
If we have stocks, we can ship from a minimum of 1 kg sample in a few days.

We also manufacture customorder materials in amounts of 300 kg

and up (Some materials are allowed 50 kg) in as few as 3 weeks.

                                      High-precision thickness
               We guarantee thickness tolerances that cannot be reproduced by competitors.
                     Example:
                                  t <0.30mm     Tolerance ±1 - 3 μm guaranteed
                                     0.30 mm≤t     Tolerance ± 1% guaranteed

    Ability to add multiple features
                          We are capable of adding a variety of features to metallic materials resin coating, plating, bonding different kinds of metal, multigage skiving, etc.
