Round Pipe Production Line For Petroleum Or Natural Gas API Tube
Mill
Product Description
API pipe mill is specialized for manufacturing straight welded pipe
for petroleum and gas pipelines.Taking hot-rolled steel as raw material, it produce required pipes
through cold roll forming and suitable welding methods like H.F.
welding, submerged arc welding and so on.
The whole production line adopts ‘ZTF’ forming technology.
Materials: L245,L360,A53,J55,N80 ,X42,X46,X52,X56,X60,X65,X70

grade, coil weight and automatic degree.
Q: What should I do if I just start a new business?
A:Contact us immediately ,we provide free consultant for pre-sales
service .Also we can help you to solve the raw material (steel
coil) purchase,worker training,international market price.
Q:How do you do QA?
A:We have special team to do strict QA,this is one of our
strengths:
(1)Every gear box will be tested for 8 hours with oil inside to
guarantee there is no leak.
(2)Every shaft will be inspected for the centering jumpiness.
(3)Every roller will be checked to make sure its in the range of
tolerance critical parts will be inspected for all dimensions.
Q:Why I should choose you,what are the differences between you and
other Chinese suppliers?
A:We are concentrate on this industry for more than 20 years,and
especially in pipe making machines. Our pipe making machine line
directly export to Russia,Vietnam,lndia,Indonesia,and many other
countries in Asia, Africa, middle east and South America.
