Tong Yu is the largest production base of ductile iron pipe mould in Asia, Our pipe mould are available mainly in diameter for DN*0 to DN***0mm, Ductile iron pipe mould is a compulsory toll in producing ductile iron pipe .It is rather expensive and its price takes a large proportion in the product cost of casting pipes. So it is of great significance to improve the quality of pipe mould and extend their life .

 

It has been proven that ,the performance and service life of our pipe moulds competent with that of the moulds produced in America and Germany, Tong Yu ductile iron pipe mould have been applied in various larges casting pipe manufactures in China ,and exports to many regions like Japan ,and Southeast Asia.

 

Clients are required to offer their drawings and technical requirement, Which will transferred to technical department(heat treatment center, large forgings research center, mechanical research center, and welding department, etc,) for confirmation and accounting, Then we will offer you the quotation, The ordered products will be put into production as soon as possible after clients have placed an order.  For any problems rise in the product line,  We will contact and discuss with our clients directly.

 

 

Specification of pipe moulds















 

1. During the smelting process, strict control is required both for the prescribed elements(*1CrMo*0) and for some harmful elements and gas like P S Pb Sn As Sb Bi and H O N
2. To guarantee that the pipe moulds have reached our flaw detection standards and that the forged blanks own refined grains, we have employed strict forging technique upon the ductile iron pipe mould.
3. After rough process (drill inner holes), A quenching and tempering treatment is given by vertical pit furnace upon the pipe moulds for further refined grains and higher comprehensive mechanical properties.
4. CNC equipment is adopted for finishing for high processing precision.
