Our concrete/cement pipe mold pallets/bottom brackets and rings are made of heavy-duty cast steel for maximum durability and longevity. It is then precision machined on a CNC lathe to ensure complete dimensional accuracy and excellent surface quality with smooth edges every time.

Due to the control of the epidemic, delivery trucks are not allowed to leave the expressway, and they must be picked up by someone from the port storage yard with the company’s business license. After paying  CNY350 to the company that is running the port yard, the yard sent someone to pick up the truck, but the truck was affixed with a seal. With this seal, the truck could not enter the yard due to the epidemic prevention policy of the port yard. I had to hire forklifts and another trucks from the port again, and reload the goods from the previous trucks to the trucks from the port, and then delivered the goods to the designated storage yard. And we paid an additional CNY500 for this.

The special cast silicon aluminum heat exchanger for commercial condensing low nitrogen gas boiler is cast from silicon aluminum alloy, with high heat exchange efficiency, corrosion resistance, durability and high hardness. It is applicable to the main heat exchanger of commercial condensing gas boiler with rated heat load below 2

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.

Most of the standards covering pipe and fittings manufactured by AMERICAN Cast Iron Pipe Company have been prepared by the American Water Works Association Standards Committee A21. Other applicable standards generally cover specialties or refer to ANSI standards.

PIPE MATERIALThis segment is meant to assist in the identification of pipe material which has been used in the utility industry in North America, roughly over the last 230 years or so. This can be a major issue today with the vastly growing number of vacuum test holes being dug, and the operator’s need to know “what kind of pipe material is that?”.

Ductile iron pipe is the successor to the tried-and-true gray cast-iron pipe. It has been in use since the year 1455 in Germany and came to the United States in 1817. Over 600 utilities in the United States and Canada have used cast-iron mains for over 100 years.

Concrete pipe cannot compare to Ductile Iron when considering their respective approaches to internal pressure design; and Ductile Iron Pipe is much easier to install and operate than concrete pipe.

Cast iron pipes were used during the construction of homes throughout the last century. It was only until relatively recently, in the 1980s, when builders stopped using cast iron pipes during the construction of homes.

Vibrator System ; The vibration system of the machine is closed circulation system with liquid oil. The automatic lubrication system is switched on with the machine is in operation. High vibration and heat resistant SKF or FAG bearings are used in the vibrator.

Concrete pipe machines are specialized equipment used in the manufacturing process of concrete pi

There are many ways to make a concrete pipe,commonly used inner and outer mold assembly pouring method, spin-casting method and rolling centrifuge tube method of suspended roller cement pipe machine.

Midt-Norsk Betong has its headquarters in Verdal, close to Trondheim, Norway. For slightly over a year, a brand-new factory has been in operation only a few meters away from the old site. The plant produces precast units for civil engineering and supplies the central part of Norway, i.e. the region around Trondheim. The company management decided to “put all eggs in one basket” and to invest in the growing infrastructural market.

A concrete pipe mold is a specialized formwork used in the manufacturing process of precast concrete pipes. This is a formative tool utilized in the production of precast concrete pipes, made from various materials such as polyurethane, polypropylene, timber, steel, silicone, and ABS. The mold shapes the concrete into a pipe with precise dimensions as the concrete sets within it, a process akin to using a hollow block mold for creating blocks, and once fully cured, the pipe is removed, ready for use or further processing.
