Chinese Ductile Iron Pipe 1

[stanier]

Has anyone quality control problems with this supplier

Xinxing Ductile Iron Pipes Co., Ltd of Beijing.

They advertise minimum orders of 500tons so would be a major player.

Is this manufacturer acceptable to your local authority?

There are several manufacturing plants of Xinxing. I suggest you to directly contact this manufacturer for further assessment...

Go with U.S. products. At least you have someone to go back to if something goes wrong. With Chinese products, if something goes wrong good luck!

We had some serious problems with Chinese piping on a project in Winnipeg...

The 10" dia pipes failed at 10% or their rated capacity... and we had mill test reports that they were A53 grade B... THis was posted in an earlier thread (about a year ago), and the problems have yet to be resolved.

Just a caution.

Didn't I read a recent article that the Chinese Government forbids the use of Chinese made pipes on critical projects such as power plant constructions?

chicopee,

Could you please share the article or source of reference? Thanks a lot...

I'm pretty sure the Chinese government's ban on Chinese piping is an urban legend. If it was ever real, was just a temporary knee-jerk reaction to a catastrophic failure of a counterfeit pipe in the main steam line at the Huadian Datong power plant in 2006. The rumour was broadcast by a widely forwarded email chain, a copy of which is available here:

This generated a lot of fear and discussion at the time, including on thread330-172967

Our company took this seriously and took a close look at our suppliers list at the time. But what we found was that some key grades of steel just aren't manufactured anywhere outside of China anymore, so banning Chinese steel just isn't realistic. I can say that we have built nuclear plants with Chinese-manufactured pipe, and they run just fine. Vigilant QA surveillance of suppliers is always important, but it doesn't make any sense to single out China.

Not sure about ductile iron piping from China but there is extensive documentation on the poor quality of Chinese cast iron piping.

ROFL! TrippL, I dearly hope that was fully intended as dry wit!

Hi stanier

We've had Xinxing as the supplier in a project.
- Quality control docs were fine (3rd party control, Chinese though)
- Some quality issues with the cement lining
- failure in proper packing
- disastrous ship transport

Put all your concern for proper packing and shipping. Please let me know if you would like to know some aspects specifically so perhaps I could tell more about them.

We had a pile of 'lab tickets' that had identical properties... looked like they xeroxed the one and just changed the numbers...
