DIN2391 ST37.4 ST52.4 hydraulic pressure line cold drawn seamless pipe
DIN2391 ST37.4 ST52.4 hydraulic pressure line cold drawn seamless pipe mainly used in pressure line ,
can bear high pressure ,also can bend in various shape of tubes.
DIN is a Germany standard.
Bright annealing seamless precision steel tubes is our main product,Torich keep various sizes of high pressure
seamless Steel tubes and Galvanizing tubes,so small quantity is also available and can be quick deliver to your side.
What we can support is that no any corrision after 120 hours' salt spary test.Cold galavanized(eletrogalvanizing)in bright pipe.
It will be strong anti corrosion & rust when passivated in zinc coating.
Torich’s target is make you easy to buy precision seamless steel tubes from China easy.
Reasonable price with good quality in efficient way.
