For HZB, 2015 is a new start, a real start to the market, and a start to accept the test of the market. We will work around two aspects

The year of 2015 is a year of reform and innovation of the joint-stock company. The joint-stock company has established new policies and objectives: One Body, Two Wings and Second Entrepreneurship. Facing the new goals set under the new situation, the locomotive company will focus on two things in 2015:

In 2015, the trade union of the company closely focused on the strategic objectives and tasks of the company, combined with the characteristics of the trade union itself, earnestly implemented the Work Regulations of the Trade Union of Enterprises, innovated work, served the enterprise and employees.

In 2015, the company put forward the strategy of "One Body, Two Wings and Second Entrepreneurship". Under the guidance of One Body, Two Wings, the marketing center will change the past thinking of single pursuit of low-cost expansion and scale development of steel pipe manufacturing, and determine to focus on financial trade, research and innovation, enhance the hematopoietic function, enhance the strength of the enterprise, and achieve enterprise take-off on the basis of steel pipe as the main business.

Precision steel pipe is a kind of high-precision steel pipe material after cold drawing or hot rolling. Because of its own advantages, it is mainly used to produce pneumatic or hydraulic components such as cylinders or oil cylinders. Next, the precision steel pipe factory will summarize its characteristics for you.

At present, most of the seamless steel tubes produced are hot-rolled. Due to high temperature, the deformation resistance is relatively small. Usually, steel plates are used to complete the rectification and rolling process. In this operation, it is also necessary to consider the specific thickness. If the accuracy requirement is relatively low, there will be no shape problem. The main problem is control. That is, in terms of temperature control, it is also a problem that needs to be considered at the same time. It can be said that this part of consideration is also very important.

​Do you know how to select high-quality seamless precision steel pipe? In this issue, we will mainly share the selection skills of high-quality seamless precision steel tubes for you. Let's learn from them if you need them.

At present, there are many kinds of steel pipes on the domestic and foreign markets. They are designed with different materials and manufacturing processes to meet different requirements for practical use. In this issue, we will discuss the relevant information of seamless precision steel tubes with you.

The cold brittleness (or low temperature brittleness tendency) of cold rolled bright tubes in use is expressed by the ductile brittle transition temperature Tc. The Tc of high purity iron (0.01% C) is at - 100C, below which it is completely brittle. Most alloy elements in the cold rolled precision bright steel pipe increase the ductile brittle transition temperature of the cold rolled precision bright steel pipe, and increase the cold brittle tendency. When ductile fracture occurs above room temperature, the fracture of cold-rolled precision bright steel pipe is dimple fracture, and when brittle fracture occurs at low temperature, it is cleavage fracture.
