The Problems Related To Straightness in The Important Index Of Seamless Steel Tubes

As an indispensable and important tubes in modern industrial production, seamless steel tubes is widely used in various industries such as petroleum, natural gas, chemical industry, electric power, machinery manufacturing and so on. Many enterprises will focus on the hardness, corrosion resistance and mechanical properties of seamless steel tubes when purchasing, and often overlook an important indicator for assessing the quality of steel tubes - straightness.

Straightness refers to the linear deviation of the tubes in the axial direction. The better the straightness of the steel tubes means that it can operate more stably and accurately during processing, installation and use. If the straightness of seamless steel tubes is not up to standard, it is very easy to have deviation in the subsequent work such as turning, drilling and assembly. For example, in the turning and drilling process, poor straightness of the steel tubes will accelerate the wear and tear of tools and equipment, frequent replacement of tools, downtime and equipment maintenance inadvertently increased production costs. In addition, the poor straightness of the steel tubes in the production process is easy to jump or offset, increasing the safety hazards, threatening the safety of the operator, and increase the risk of accidents in the enterprise.

Huagang Industrial patent escort, strength to ensure accuracy

Zhangjiagang Huagang Industry Co., Ltd. has been focusing on the seamless steel tubes industry for many years, and understands the importance of the straightness of seamless steel tubes to the customer's production, from the practice of raw materials to the improvement and optimisation of the production process and equipment, to ensure that the straightness of each steel tubes is far more than the industry standard.

Strict selection of high-quality raw materials: we use high-quality round steel from Baosteel, Huaigang, Zhongtian and other large steel mills to eliminate bending caused by uneven raw material from the source;

Advanced technology support: through years of practical experience to optimize the production process, improve the straightness of the steel tubes, to avoid deformation and bending of the steel tubes;

Patented equipment escort: actively study the influencing factors of straightness and boldly try to optimise and improve the production and inspection equipment, precise control of steel tubes straightness error ≤ 0.3mm / m or less;

Full-process quality inspection system: temperature, speed, pressure control in the production process of each process are equipped with professional testing equipment, wear and tear of production equipment maintenance are arranged for regular inspection and maintenance, to ensure that the finished product straightness stable high standard, reduce the burden of customer processing.
