Pipe mold

TongYu is the largest production base of ductile iron pipe mould in Asia. Our pipe moulds are available mainly in diameter from DN50 to DN2600mm. Ductile iron pipe mould is a compulsory tool in producing ductile iron pipe. It is rather expensive and its price takes a large proportion in the production cost of casting pipes. So it is of great significance to improve the quality of pipe molds and extend their life.

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

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

Specifications of Pipe Moulds

Material 21CrMo10
Types water-cooled metal pipe mould, hot molding pipe mould
Specification DN50-2600mm

Manufacturing Process
Raw Material Smelting – LF Refining – Vacuum Degassing – Iron Ingot Casting – Forging – Heat Treatment – Roughing – Quenching and High-Temperature Tempering – Semi-Finishing – Stress Relieving – Finishing – Packaging

All of the steps from smelting, forging, heat treatment, flaw detection, to mechanical processing are controlled strictly and accurately.

Quality Control
1. During the smelting process, strict control is required both for the prescribed elements (21CrMo10), 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 moulds.
3. After roughing process (drilling 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.
5. All of the properties of our pipe moulds are superior than the GB/T 25715 centrifugal ductile iron pipe mould standards.

Eyce Mold 2.0 – Ice pipe Mold

This is the Official Ice pipe Mold by Eyce, if you like hitting pipes that are pure chilled this is definitely for you. The mold allows you to make a pipe purely out of ice, no glass only ice, so when your finished with your smoking session all you have to do is just let it melt.

How to make the Ice pipe

Simple! Unpack all the equipment, place the mouthpiece inside at the top of the mold, give it a feel to make sure that the mouthpiece is at the top, then insert the core pin into the mold aswell. Now fill the mold to the point where there is an inch free at the top, then place the stand in and insert he plug so it wont spill anywhere in the fridge. Leave in the freezer for up to 12 hours, 12 hours later, take the mold out of the freezer and run under hot water for 60 seconds and leave in the sink for 8 minutes, then run hot water again for 60 seconds, then squeeze out the pipe and there you go you just made a ice pipe.Then when your finished with the pipe just let melt in the sink and give the parts a wash.

When you have it made you’re ready to use the Ice pipe, be aware that you will inhale pure chilled vapor.

Easy to Use

You can make a pipe within 3 minutes, but you will have to wait 12 hours for the water to freeze.

Cleaning Your pipe

When the pipe is melted, all you have to do is give all the parts a good cleaning and you are ready to go for the next pipe making session.

If you like hitting bongs that are pure chilled this is definitely for you. The mold allows you to make a pipe purely out of ice, no glass only ice! COOL right? ]]>
