Recently, the new steel grade of 25MnVYD sucker rod developed and produced by Tangshan Iron and Steel Co., Ltd. passed the fatigue performance test at China University of Petroleum. Its main performance indicators fully meet the requirements of the D-class sucker rod steel standard specified by China National Petroleum Corporation. In order to obtain a "entry permit" for mass entry into the market. The successful development of this steel grade marks a major breakthrough in the development of Tangshan's new steel for sucker rods, making Tangshan the second domestic enterprise to master this technology. At the same time, it has created conditions for further broadening the market, improving competitiveness and reducing production costs.
Steel for sucker rods is a special type of steel used primarily for the production of sucker rods for oil production. Previously, domestic steel for sucker rods generally used 20CrMoA, a traditional steel grade. However, due to the high price of ferromolybdenum, the cost of producing 20CrMoA sucker rod steel is very high. To this end, Tang Gang listed the "research and development of new steel grades for sucker rods" as one of the major technical research projects of the company this year, and formulated rigorous research targets and tackling measures. The relevant technical personnel have conducted research and investigation on many domestic sucker rod production plants and oil fields. On the basis of detailed understanding of market demand and user requirements, the steel type selection and process route design were completed in the shortest time, and laboratory research was carried out. The analysis further optimized the chemical composition and hot rolling process to ensure the successful development of new steel grades.

Vacuum Formed Signage

Vacuum forming signage is a common type of sign, widely used in sign making due to its advantages such as beautiful appearance during the day and bright evening, good weather resistance, and durability. The vacuum forming signage character signboard consists of three parts: an acrylic vacuum forming panel, a luminous character box, and a luminous character light source.


Advantages of vacuum forming signage:

1. Attracting attention: vacuum forming signage breaks through traditional two-dimensional expression techniques, using three-dimensional shapes to activate people's spatial imagination, and has a strong sense of three-dimensional shape.

2. Various color:

3. High cost-effectiveness: balancing both day and night effects. Not easily deformed or faded.

4. Green and environmentally friendly: Due to the complete recycling and reuse of acrylic materials, it is considered a form of green advertising.

5. Good performance: It has good corrosion resistance, rain resistance, fire resistance, and self ignition resistance.

6. Long service life: with an average lifespan of 80000-100000 hours;

7. Energy conservation and environmental protection: The safety voltage of the lighting system inside the font is 12V, which does not pose any harm to personal safety. The entire product does not produce light pollution or chemical pollution during use.

8. Widely used: The vacuum forming signage are widely used in store advertisements and advertisements in shopping malls, hotels, parks, buildings, and various institutions.
