Since the beginning of this year, the industrial sewing machine market in our country has witnessed an exciting and enthusiastic situation. Both production and sales have been booming and exports have shown significant growth. According to statistics from Nanjing Customs, in the first two months of this year, Jiangsu exported a total of 17,000 industrial sewing machines worth 1.956 million U.S. dollars, an increase of 1.5 times and 2.1 times over the same period of last year. Experts in the industry believe that the significant increase in the export of industrial sewing machines indicates that China has the strength of the world's sewing equipment production and sales center. At the same time, the state implements a full export tax rebate system for the export of sewing equipment, which encourages the enthusiasm of enterprises to export sewing equipment; The cancellation of the global textile quota system has promoted the rapid development of the entire garment industry. In many countries, including China, the number of garment export orders has increased, and the production capacity of garment companies has expanded, and the demand for sewing equipment has increased significantly. In Southeast Asia, Eastern Europe, South America and other countries and regions, the large demand for medium and low-grade sewing equipment has provided a broad market for the export of China's industrial sewing equipment. Although the industrial sewing machine export situation is gratifying, but the industry experts are not without concerns, according to another data from Nanjing Customs shows that in the first two months of this year, Jiangsu Province imported 5,369 sets of sewing machines, the import volume is only 31.6% of the same period of export volume, but imports The amount of 5.93 million US dollars, is 3 times the amount of exports over the same period. According to industry sources, the current total annual production of sewing machines in the world is 16 million units, and the annual trade volume is about 7 billion US dollars. The annual output of sewing machines in China accounts for nearly 45% of the world's total output, while the export trade accounts for less than 5% of the world's total trade volume. . China's industrial sewing machine export market is "it looks very beautiful." The expert analysis, on the one hand, is that China's sewing machine export products are mainly low-end and high-end high-price products are less involved; on the other hand, there are many domestic manufacturers, export competition is fierce, and export product quality and technical content cannot be completely guaranteed. Limit the further increase of the export of sewing equipment in our country. With rising raw material prices and low technological content, the profit margins of medium- and low-end sewing machines with low added value will be even weaker. Enterprises will be at a disadvantage in competition and will directly threaten their own development. China's sewing machine manufacturers must seize the opportunity to speed up the technological transformation, increase the technological content, develop new products that meet market needs, improve product quality and quality, strive to create a world famous brand, and use brands to generate more foreign exchange. Government departments and industry associations must also strengthen management and guidance to ensure the healthy and sustainable development of sewing equipment exports.

Relevant description of products:
Retrieve the inner tube with an overshot without lifting out the whole rods string to obtain the core, the wireline coring system lifts the underground core sample out of the borehole through the overshot to take back the entire inner tube and conduct sampling analysis. This improves productivity of the work site and guarantees safety of core sample during drilling down.
The system is realized through a fully independent inner tube. During its working, the inner tube does not connect with the overshot but locates at the bottom of the coring Drilling Rod directly (behind the coring drilling bit). An assembly device is installed on top of the inner tube, which includes coring and recycling functions. When the inner tube is full of core sample, the overshot is placed to the bottom from the borehole through a steel wire rope and lifted out by a winch. After the inner tube assembly is lifted to the surface, an empty inner tube is placed to the bottom of the hole to recover the drilling. This improves well drilling efficiency.
Our company provides core barrel assmeblies of different diameters to meet customers' demands. The wireline coring system is applicable for most drilling conditions and standard DCDMA hole sizes (B, N, H and P).
Currently, the company provides two models of wireline coring systems: double-tube and triple-tube
Core barrel assembly: It consists of inner tube and outer tube groups.
The inner part consists of the following parts: spearhead assemly, retrival components, core sample collection component, landing shoulder, stop ring and other parts.inner tube group, independent from outer tube group, collects core sample sample during well drilling.
The outer tube part consists of parts , which includes locking coupling, adapter coupling, outer tube, etc. The outer tube group that is kept at the bottom of the hole all the time holds the inner tube assembly during drilling.
The triple tube coring system AU3 has the same components as the dual-tube. And its interior has a third tube that is known as liner tube of the inner tube.
Liner tube of the inner tube is placed in the inner tube. The triple tube system can realize overall recovery ratio of core sample when drilling stratum with coal, clay or bigger crack. The liner tube or split tube keeps the core sample at its receiving status to collect or load and store easily.
Only N, H and P sizes are available for the triple tube coring system.
