With the recovery of the world economy, the import and export of China's valve products has also increased, but the competition in the international valve market is also increasing. Because there is still a big gap between high-end technology and foreign large manufacturers, in the coming period, product technology will become a bottleneck restricting the development of China's valve products.

In addition, China's valve industry in the industrial structure, the industrial chain of the valve industry, as well as the industry's degree of specialization, have a large gap with foreign companies. How to break through these shortcomings is a crucial issue in the development of the industry.

1. Integration of enterprise development needs Although the valve industry has partially completed the accumulation of original capital, there are still many problems, such as intensified price wars, quality problems to be improved, etc., plus the implementation of the new "Labor Law" and the exchange rate. The changes and raw material prices, which make valve companies feel unprecedented operating pressure, especially those small businesses are even more unbearable.

In recent years, with the country’s emphasis on environmental protection, sewage treatment projects in various regions have become important markets for the company. However, due to the small scale of the company, only a few good projects can be picked each year, and more orders cannot be taken over. It is difficult for small and medium-sized enterprises to grow bigger and stronger on their own, so they choose to unite with other companies that have their own advantages. This will not only get more orders, but also accelerate business development.

2. Upgrade of brand needs to be integrated Currently, most of the products in the valve industry are of low grade and large in repeatability. Many companies often have valves that are produced in a variety of products and specifications. What the market needs is what it produces and what it wants to put into production. Some companies lack innovation, not to mention products with independent intellectual property rights. Individuals still follow the example of education, copying, and imitating others' products. Enterprises do not have their own branded products, like a road to the black, not to mention the development and expansion, simply can not deal with fierce market competition.

In this case, these companies need to change their operating methods and ways of thinking, and they can join hands to create a brand.

3, strengthen the certification to accelerate the industry integration of the valve as a special product, supporting a variety of projects. In the past two years, with the continuous deepening of the bidding system for domestic engineering projects, TS certification has gradually become an important condition for market access. The valve industry has also experienced the phenomenon of icy and heavy fire. Large enterprises cannot complete orders, and small enterprises Can not get orders, the rapid emergence of the entire valve industry from this phenomenon.

With the start of the second pipeline project of “West-East Gas Pipeline” and the launch of a number of national projects such as environmental protection and pollution control, together with the large number of foreign orders entering the country, the market for the valve industry has been continuously expanding, and the market prospects are very promising, but TS certification is An important "threshold", there is no TS certificate and you want to order, you can only join a large group of companies or a number of companies. However, if you want to join a large enterprise group, you must first integrate and standardize small businesses.

Metallographic Microscope Series

The structure of optical metallographic microscope generally includes magnification system, optical path system and mechanical system, among which the magnification system is the key part. The preparation process of metallographic samples generally includes five steps: sampling, rough grinding, fine grinding, polishing and etching. The interception of samples from metallic materials and parts to be tested is called "sampling". Selection of sampling sites and grinding surfaces must be based on analysis requirements. The size of the sample is not uniform, from the perspective of easy to hold and grinding, the general diameter or side length of 15~20mm, 12~18mm high is suitable. For those too small, irregular shape and the need to protect the edge of the sample, you can adopt Mosaic or mechanical clamping method. For the inlay of metallographic sample, the appropriate size (about φ L5-20mm) of steel tube, plastic tube or paper shell tube is placed on the smooth plastic (or glass) plate, and the sample is placed in the tube to be ground face downwards into the filler, which can be solidified and hardened for a period of time. 3) Chamfering On the premise of not affecting the purpose of observation, the edges and corners on the sample should be ground off to avoid scratching the sandpaper and polishing fabric.Metallographic Microscope 1
