The low carbon steel brake tube is supplied in single wall and double wall(Bundy Pipe). The products conform to ASTM A-254-91, A-512-91A and ASTM A214 and A513 in material and quality.

A double-walled pipe is a secondary contained piping system. It is a pipe within a pipe, or encased in an outer covering, with an annulus (interstitial space) between the two diameters. The inner pipe is the primary or carrier pipe and the outer pipe is called the secondary or containment pipe. The great majority of double-walled piping applications involve wastewater, groundwater, and process safety.

Remarks:

Inner: used wear resistant alloy steel, Outer: lower carbon steel. 
Used special composite process. 
Between the double wall combinated closely. 
Inside material is so wear resistantace to transport more valume concrete. 
Outside low carbon steel play the role of protection. 
we can product other specifications to the needs of customer.
