It is reported that due to the rise in the prices of raw materials such as steel, it has affected the sharp rise in the prices of auto parts and components, ranging from as little as one screw plug to as large as the gearbox. Most auto brands in the market have raised the prices of parts and components. The prices of individual parts and components have even doubled and climbed. The price of screw plugs has risen from the original price of 8.5 yuan to the current price of 11.8 yuan, an increase of 38.8%.
The reporter learned from the 4S shop of Southeast Auto that the car dealership network that has been building CLV (lifetime value users) as a service strategy covers 31 provinces, cities, and autonomous regions across the country, and the coverage of outlets in 100 prefecture-level cities nationwide is as high as Above 90%, the number of distribution outlets ranks third in the national automotive industry. From the second half of last year, South East Motors has adjusted the prices of parts and components of the entire vehicle series several times in order to ensure the quality of parts and components. This is to ensure the further expansion of market share while ensuring after-sales service. In recent days, it has once again significantly adjusted. The price adjustment of spare parts as many as 500 items, including more than 200 commonly used spare parts, an average drop of 50%, such as lioncel's taillights from the original 734.38 yuan down to 366 yuan, fulika fuel filter ( With stand) from 73 yuan to 73 yuan, headlamps from 768.57 yuan to 396 yuan, the overall price of accessories has generally been lower than the equivalent model.
According to insiders from Southeast Automotive, the adjustment of Southeast auto parts costs was mainly due to the advantages of a complete supporting system and supporting cost in Southeast Motor City, which is known as the “Southeast Model†in the industry. The supply of parts and components of Southeast Automotive is mostly provided by suppliers with international and domestic reputation in Southeast Motor City. Therefore, the small supporting radius provides convenience for the reduction of inventory, and also reduces the related costs of logistics and transportation, and maximizes Control unnecessary costs. Recently, Southeast Automotive has taken the lead in introducing quality demonstration lines among component suppliers to urge and encourage suppliers to continue to maintain the excellent quality of their products.
From this point of view, Southeast Automotive can establish a good reputation and brand reputation among consumers in such a short period of time. The marketing aim is always to place the strictest producer of product quality and always maximize the interests of consumers. Inseparable.
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.
