During the “11th†period, 31 buses equipped with Cummins' new ISF3.8-elevated four-emission engine were officially put into use in Shunyi, Beijing. They took on the high-load and heavy-duty transportation tasks of the 7th China Flower Expo and successfully transported a large number of tourists to and from the airport. Yu Shunyi Flower Expo exhibition hall line. In addition to the successful service fair, the ISF 3.8-liter eco-friendly engine officially put into operation in Beijing in June this year was also launched in batches in the small bus passenger market in Pinggu and Changping, providing high-performance, low-emissions for public transportation in the suburbs of Beijing. Environmental support. It is reported that the vehicles include 45 7.7-meter and 7.5-meter buses produced by Suzhou Jinlong, which were put into operation by Pinggu Xintongshun Passenger Transport Service Co., Ltd. and Changping Wanjiatong Passenger Transport Co., Ltd. in Pinggu and Changping respectively; 31 cars produced by Changan Bus Co., Ltd. are 8.5 meters long. The bus was put into use by the Shunyi Junma Passenger Transport Company before the opening of the Shunyi Flower Expo. These buses are all equipped with the Cummins ISF 3.8 I Quad. The Cummins ISF 3.8-liter engine has been tested in Darlington, England, as well as the domestic 35,000-hour bench test, 1.5 million-kilometer vehicle reliability test, and durability test, as well as various tests in extreme environments. The product performance and technical indicators All have excellent performance and can meet the different requirements of customers around the world for high-end, clean power products. Cummins ISF engine can meet the European IV/National IV environmental protection standard at the beginning of production, and its modular design enables the platform to be quickly upgraded to meet Euro V and future stricter emission regulations. Polyvinylidene Flexible Tubing
Appearance: the appearance is black smooth
Flexible composite high pressure conveying pipe (flexible composite pipe for short) is a kind of High Density Polyethylene Rtp,Polyvinylidene Fluoride,High Density Polyethylene,Pvdf Polyvinylidene Fluoride Shaanxi Yanchang Petroleum Northwest Rubber Flexible Pipe Co., Ltd. , https://www.cnrtp.com
non-metallic pipe with multi-layer structure, which is generally composed of inner lining layer,
reinforcing layer and outer protective layer. Flexible composite pipe has certain flexibility and can be
coiled into hundreds of meters to several kilometers to realize continuous laying. Flexible composite
pipe is also called coiled reinforced plastic pipeline pipe and reinforced composite plastic pipe (RTP)
in foreign countries.
Flexible composite pipe can be divided into land flexible composite pipe and downhole flexible
composite pipe according to the laying mode; It can be divided into flexible composite pipes for oil and
gas fields and flexible composite pipes for coal mines. According to the structure, it can be divided
into adhesive flexible composite pipe and non adhesive flexible composite pipe.
