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

This morning we learned that a 6.2-magnitude earthquake occurred in Jishishan County, Gansu Provi

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.

The concrete cylinder is the most common sample type for tests of concrete compressive strength. There are other ways to determine concrete strength, and some methods may be more cost-effective and arguably better, but concrete cylinder testing remains the standard for acceptance.

Not long ago, I drove past a construction site on my daily commute and noticed a set of four test cylinders, apparently cast during a recent concrete placement. I also noticed they were standing fully exposed on a sunny day with temperatures in the high 80’s (31ºC) and perched precariously on a pile of dirt.

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.

One of the most crucial elements in the production of high-quality concrete products are the joint rings (pallets, headers and set rings) that form the male and female ends of the pipes.

Finding the right material for your exterior patio, walkway or driveway can seem challenging. Balancing budget with design, maintenance and durability leaves you with lots of decisions to make. As a result, you may find yourself researching various materials to use for your next project.

My first hands-on exposure to installing stamped concrete was back in 1976 at the innocent age of 14. I was working for my father at the time, helping him stamp a crosswalk in the busy downtown area of Alameda, Calif. The brick-pattern stamps we were using were made of plastic, and to prevent them from sticking to the fresh concrete, we stamped through a layer of 1-mil plastic. Once the stamping was complete, we added texture by dragging a broom across the surface.

There are a lot of steps involved in stamping concrete, and only a short window of time in which to get them done. Unlike when applying a decorative coating or stain to hardened concrete, crews need to complete the entire stamping process before the fresh concrete sets.

Truck mounted dual piston pumps are commonly used for concrete pumping. Invented in 1931, and with subsequent improvements, these pumps utilize an alternating and synchronized movement of two pistons connected to a valve system to push the concrete through the pipe system [18]. While one piston is pushing the concrete into the pipes, another piston is filled with concrete by suction. A stepwise control of pressure and flow rate is nowadays typically enabled through a remote control system.

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.
