The FAW Volkswagen Sagitar, which has been plagued by the "broken shaft door" , does not seem to have gone down the altar. In the January 2015 car sales list released by the China Automobile Association yesterday, FAW-Volkswagen Sagitar still ranked third in the sales of the car brand in January 2015 with a sales volume of 31,100 units. Yangtze Daily reporter learned that, starting from February 2, FAW-Volkswagen Sagitar issue 560,000 car recall officially launched specific programs in question Sagitar vertical arm rear axle, install a metal plate (called "patch"). However, the FAW-Volkswagen latest data show that as at 16:00 on February 10th, there are 111,900 Super Proton car to complete the installation work lining, accounted for only 19.9% of total recall. In addition, there are still owners who are unacceptable to the public 's recall plan. Some insiders said that although the "patching" can more than double the strength of the rear axle arm, it can not completely avoid the broken shaft. If this solution is currently solved If the solution does not solve the problem, a new solution will be introduced. Just recall to start soon, Sagitar solutions will be faced with an alleged "illegal modification" test. On February 5, a Shandong netizen asked the Zaozhuang Vehicle Management Office whether the installation of the lining was illegally modified , and the response given by the vehicle management was “confirm that the measure was illegally modified and needs to be restored to the original state and placed at 500 yuan. The following fine." This makes the majority of car owners question the public 's recall plan. However, in response to the "illegal modification " statement, the Volkswagen official immediately responded on February 9. "The Motor Vehicle Registration Regulations have clearly and thoroughly stated that the so-called illegal modification refers to unauthorized changes to the shape of the motor vehicle and The registered technical data has been modified . The metal lining plate installed in the recall plan has been reported to the State Council Product Quality Supervision Department for filing, so there is no violation of relevant regulations." 　　 Gong Xingbo, director of public relations department of FAW- Volkswagen Market, said on February 9 that "the design of the coupled rod rear suspension itself is no problem. The recall of the sagitar installation metal lining is to increase insurance on the basis of safety." At the same time, Volkswagen (China) investment Co., Ltd. Hooper, chief marketing officer also denied a design flaw after suspension problems Jetta coupling rod. Both said that for the use of coupled rod rear suspension, the public may make some improvements, but will not give up. At the same time, the installation of metal linings for recalling vehicles is not intended to save costs, but is a globally unified solution for Volkswagen . It is made of the same steel (2514, 31.00, 1.25%) as the coupled rear suspension, providing the owner with “double insuranceâ€: the first weight is to maintain the stability and handling of the vehicle after the longitudinal arm breaks. The second is to provide a warning tone to remind the owner to go to the nearest dealer for repair. Not "illegal modification" Official response Technical staff Can strengthen the rear axle longitudinal arm more than double the stiffness "I don't dare to go high speed when I go home for the New Year." Mr. Huang, the owner of Wuhan, said that he is not satisfied with the public 's recall plan. He said, “Most owners do not recognize the new Sagitar recall plan, because the remedy does not eliminate the safety hazards of the vehicle during driving, and it has not been fundamentally resolved. Vehicle safety issues." Yesterday, with these questions, the Changjiang Business Daily reporter came to a repair station in Wuhan FAW Volkswagen . "First remove the bracket, and then install the metal lining, and install one on the left and right sides, a total of two." The technician at the repair station said that the sagitar coupling suspension is easy to break in the rear axle longitudinal arm. Only 3 mm, with a 5 mm thick metal lining, the strength can withstand 8 mm or less, but it has more than doubled the stiffness." As for whether it can be converted into an independent suspension, Liu technicians said that it may breed new problems in illegal modification and after-sales maintenance: "It is not only a technical problem. After you have modified the suspension, FAW- Volkswagen will not guarantee this. The increase in after-sales maintenance costs is not mentioned, and it is more likely to involve illegal modifications ." For the recall of the metal liner installed, Liu technicians believe that although the value is not high, "in the 100 yuan to 200 yuan." But it can improve the problem of the previous sagitar easy to break the axis, and when asked if there will be more In the case of a good solution, the technician said: "The manufacturer should have already tested when making the measures. If the solution ('patching') cannot solve the problem, a new solution will be introduced." "After all, the public is unlikely to have changed 560 000 Sagitar set independent suspension." Wuchang Xiong Chu Avenue FAW car repair workshop had master that, question why cars suteng angered a lot of people resent, mainly because of its "patch "The solution does not perfectly solve the possibility of Sagitar's "broken shaft", but "for the time being, there is no way to install metal lining for Sagitar . It can effectively reduce the possibility of broken shaft." A few days ago, some media reported that the Volkswagen Group also admitted that after the installation of the metal lining, there is no guarantee that the bracket will not have any problems when it is hit by an external force. However, as long as the metal lining is added, even if the bracket is completely broken, the vehicle can be safely driven for hundreds of kilometers to ensure that it can be repaired at the dealer .
PTFE lined elbow is a type of pipe fitting that is commonly used in industries where highly corrosive fluids are transported. The elbow is made of two parts – the outer shell, which is typically made of carbon steel or stainless steel, and the inner lining, which is made of PTFE (polytetrafluoroethylene).

PTFE is a synthetic fluoropolymer that is known for its exceptional chemical resistance, high temperature resistance, low coefficient of friction, and non-stick properties. These properties make PTFE an ideal material for lining pipes and fittings that are used in industries such as chemical processing, pharmaceuticals, food and beverage, and water treatment.
The PTFE lining in the elbow provides a barrier between the corrosive fluid and the metal surface of the elbow, protecting the metal from corrosion and extending the life of the pipe fitting. PTFE lined elbows are also resistant to scaling and fouling, which can reduce the efficiency of the fluid transport system.
