Weichai Power announced yesterday in Hong Kong that it had signed a strategic cooperation framework agreement with Beiqi Foton for product and equity cooperation.
According to the agreement between the two parties, in the next five years, Futian promises that the supporting rate of Weichai products will not be lower than that of Weichai in 2007 for heavy-duty commercial vehicles (total mass of 14 tons and above). The rate has been increased year by year; at the same time, Foton products have been given priority for the new models of vehicles developed outside Futian's heavy-duty commercial vehicles. In addition, in addition to the foreign branded engine products that Futian has introduced and jointly produced, the company promises not to develop and produce heavy-duty vehicle diesel engines and gearbox products that compete with Weichai in the next five years.
In the agreement, Futian’s advantage is that Weichai will act as a strategic investor and take up the subscription of shares of Foton Motor’s private placement.

PVC pipe is extruded by hot pressing method after the cooperation of PVC resin, stabilizer and lubricant. It is the earliest plastic pipe developed and applied.
PVC-U pipe has strong corrosion resistance, easy adhesion, low price and hard texture. However, due to the leakage of PVC-U monomer and additives, it is only suitable for water supply system with transmission temperature not exceeding 45 ℃. Plastic pipes are used for drainage, wastewater, chemicals, heating and cooling fluids, food, ultra pure liquids, mud, gas, compressed air and vacuum system applications.
PVC pipe fittings include direct connection, tee and cross joint, and the tee is divided into 45 degrees and 90 degrees.
Advantages of PVC pipe
1. It has good tensile and compressive strength, but its flexibility is not as good as other plastic pipes.
2. Small fluid resistance: the pipe wall of PVC-U pipe is very smooth and has little resistance to fluid. Its roughness coefficient is only 0.009. Its water transmission capacity can be 20% higher than that of cast iron pipe with the same pipe diameter and 40% higher than that of concrete pipe.
3. Excellent corrosion resistance and drug resistance: PVC-U pipe has excellent acid, alkali and corrosion resistance, is not affected by moisture and soil pH, and does not need any anti-corrosion treatment during pipe laying.
4. Good water tightness: the installation of PVC-U pipe has good water tightness whether it is connected by bonding or rubber ring.
5. Anti bite: PVC-U pipe is not a nutrient source, so it will not be eroded by rodents. According to the experiment conducted by the National Health Foundation in Michigan, mice will not bite PVC-U pipes.
6. Performance test: curing time shrinkage splitting strength tensile property peel strength thermal stability application period storage period release of harmful substances.
