At present, the technical level of Chengdu copper pipe products has basically been synchronized with the international market. In particular, the production technology and equipment of air-conditioning and refrigeration pipes have been relatively mature and perfect, and the quality of air-conditioning internal thread pipes has been at the world's leading level. There are a large number of copper pipe manufacturers in Chengdu. At present, large domestic manufacturers are using technology, capital, scale and R&D advantages to promote industrial upgrading and increase market concentration. In the future, the Chengdu copper pipe industry will form a competitive landscape dominated by major manufacturers and supplemented by specialized and refined small and medium-sized manufacturers.
At present, the main enterprises specialized in the production of copper pipes in Chengdu are Hailiang, Jingyi, Jinlong and so on. Hailiang Group and Jinlong Group have relatively complete copper pipe products, which have strong advantages in production and scale. Jingyi shares mainly focus on the manufacture of precision copper pipe products, mainly for copper pipe products for air conditioning and refrigeration; Honglei Copper Company Focusing on technological innovation and focusing on market segmentation, Chengdu Copper Tube is in a leading position in high-precision copper tubes, especially in high-end precision copper tubes such as high finned tubes.
Chengdu copper pipe has excellent properties such as high strength, good toughness, corrosion resistance, pressure resistance, high temperature resistance, long service life, impermeability, inhibition of bacterial growth, health and health, and is widely used in construction water (gas) pipelines. The foreign construction industry adopted copper water supply pipeline system earlier. In developed countries such as Europe and America, Chengdu copper pipe and pipe fittings are always the first choice for construction water pipes and fittings. The copper pipe penetration rate in developed countries such as the United Kingdom, the United States and Canada has been More than 85%, has formed a relatively mature consumer market, the international market demand for copper water pipes is stable. Since the cost of copper water pipes is higher than that of traditional galvanized steel pipes, the penetration rate of China's buildings, especially Chengdu copper pipe pipes, has a certain gap with Europe and the United States.
Elevator modernization (or lift modernisation) is the process of upgrading the critical parts of the elevator in order for it to be able to handle new technology, have better performance, improve safety, and even give the aesthetics an up-to-date appeal
Most elevators are built to provide about 20 years of service, as long as service intervals specified and periodic maintenance/inspections by the manufacturer are followed. As the elevator ages and equipment become increasingly difficult to find or replace, along with code changes and deteriorating ride performance, a complete overhaul of the elevator may be suggested to the building owners.
A typical modernization consists of controller equipment, electrical wiring and buttons, position indicators and direction arrows, hoist machines and motors (including door operators), and sometimes door hanger tracks. Rarely are car slings, rails, or other heavy structures changed. The cost of an elevator modernization can range greatly depending on which type of equipment is to be installed.
Modernization can greatly improve operational reliability by replacing mechanical relays and contacts with solid-state electronics. Ride quality can be improved by replacing motor-generator-based drive designs with Variable-Voltage, Variable Frequency (VVVF) drives, providing near-seamless acceleration and deceleration. Passenger safety is also improved by updating systems and equipment to conform to current codes.

Benefits of elevator modernization
Modernization can greatly improve operational reliability by replacing mechanical relays and contacts with solid-state electronics. Ride quality can be improved by replacing motor-generator-based drive designs with Variable-Voltage, Variable Frequency (VVVF) drives, providing near-seamless acceleration and deceleration. Passenger safety is also improved by updating systems and equipment (such as double brake system, unintended car movement protection device on the brake system etc.) to conform to current codes.
