The cold working methods of steel pipes mainly include cold drawing and cold rolling. The raw materials of cold-rolled steel pipes can be hot-rolled seamless steel pipes or welded pipes. The common characteristics of the cold working method of steel pipes are high dimensional accuracy and good surface roughness. It can produce very thin (up to 0.05~0.01mm) thin-walled tubes and very thin (up to 0.3~0.1 mm in diameter) capillaries.

Internet of things meter
The Internet of Things meter is a new product that Sanchuan has taken the lead in launching in China and is also a major part of Sanchuan’s development strategy in recent years. Sanchuan shares hope to quickly increase its market in the field of Internet of things. It controlled the Hangzhou Sanchuan Guode IOT Technology Co., Ltd. (this company is a software company that provides products and services for the informatization construction of the water supply industry) by capital increase; at the same time, it signed “Intelligent Water Affairs and The Big Data Application Strategic Cooperation Framework Agreement is to build smart water services, promote the establishment of water resources management and security systems, and jointly create water resources big data applications.
The IoT gas meter is also a new product successfully developed by Gold Card in 2014. It hopes to gradually build an online platform based on the IoT gas meter in the future.
It can be said that the Internet of Things meter is the joint R&D direction of Sanchuan and Gold Card shares, and is also the platform foundation for both parties to gradually build the Internet of Things. This cooperation is mutually beneficial. Both parties will establish long-term strategic cooperative partnerships based on the principle of complementing each other and sharing resources; relying on the resources of the market and marketing, especially in the cities jointly covered by the two parties, to create synergies and jointly promote business development; In terms of technology research and development, cooperation will be conducted; resources will be shared and cooperation will be carried out in the construction of the Internet of Things platform and its data sharing, mining, and analysis.
Generally, the production process of seamless Steel Pipe can be divided into cold rolling and hot rolling. The appearance of cold-rolled seamless steel pipe is shorter than that of hot-rolled seamless steel pipe. The wall thickness of cold-rolled seamless steel pipe is generally smaller than that of hot-rolled seamless steel pipe. But the surface looks brighter than that of thick wall seamless steel pipe. The surface is not too rough, and the diameter is not too much burr.
In order to obtain seamless pipes with smaller size and better quality, cold rolling, cold drawing or a combination of the two methods must be used.
High precision cold drawn precision steel pipe is a new type of steel pipe, which is mainly characterized by high precision. There are usually two production processes of two high mill and three high mill. The precision of three high mill in producing cold rolled seamless steel pipe is higher, which can be controlled within a few wires, but the price is relatively higher.
The product specification range of cold rolled steel pipe is: outer diameter 4.0 ~ 450mm; The wall thickness is 0.04 ~ 60mm. Compared with the cold drawing method, the advantage of the periodic cold rolling method is that the shrinkage of the pass surface is large, there is no need for difficult head, and the yield is high.
Sanchuan Co., Ltd. and Gold Card Co., Ltd. Collaborate to Develop the Internet of Things Market
[Chinese instrument network enterprise vane] On May 11, Jiangxi Sanchuan Water Meter Co., Ltd. announced that it has signed a cooperation framework agreement with Gold Card High-tech Co., Ltd. and the two sides will expand their business in the “Internet Plus†field to achieve strategic upgrades. Jiangxi Sanchuan Water Meter Co., Ltd. and Gold Card Hi-Tech Co., Ltd. are both listed companies. They have extensive marketing networks and end-users accumulated for many years in their respective industries, and extend the industrial chain to downstream areas. The gas meter has been successfully introduced to the market.
