Quality defects of seamless perforated capillary tubes
Steel management properties: normal temperature mechanical properties, high temperature mechanical properties, low temperature properties, corrosion resistance. The physical and chemical properties of pipes mainly depend on the chemical composition of the steel, the organizational structure and the purity of the steel, as well as the heat treatment method of the pipe.Читати далі -
Порівняння методів фарбування труб з вуглецевої сталі
Фарбування труб із вуглецевої сталі означає нанесення шару фарби на поверхню сталі за допомогою щітки, розпилення тощо, щоб зробити сталеву трубу красивішою або підвищити захист. Покриття можна використовувати в будівництві, ремонті автомобілів, декоруванні дому та інших сферах. Поверхня предмета повинна бути повністю очищена та оброблена перед фарбуванням, щоб гарантувати міцне зчеплення покриття з поверхнею предмета.Читати далі -
Introduction to the grades of black steel pipes
Black steel pipe is commonly used in a variety of industrial applications, including pipelines, construction and infrastructure projects. When comparing Grade A and Grade B black steel pipe, it is important to consider their differences in chemical composition, mechanical properties and specific applications.Читати далі -
What are the ERW pipe making machines?
The ERW pipe forming unit initially adopted the chain drawing method. Later the United States created roll molding. The structure of the primary roll forming device is a cross arrangement of flat rolls and vertical rolls, and is mainly used to produce small diameter ERW welded pipes. After continuous improvement, the forming arrangement was changed to the form of flat, vertical roller + vertical roller group, the pipe diameter was developed from small diameter to medium diameter, and high-frequency welding was adopted. It is generally called a small and medium-sized roller forming welded pipe unit. Later, it was further developed into the row and roll type.Читати далі -
Acceptance standards for large diameter steel pipes
Large-diameter steel pipes (such as spiral welded pipes) are pipe products mainly used to transport liquids, gases, solids and other substances, and are usually made of steel. These pipes are commonly used in construction, petrochemical, industry, water supply, heating and other fields. The following is some relevant information about large diameter welded pipes:Читати далі -
How to prevent leakage of hydraulic tubes?
Hydraulic tubes are basically divided into fluid pipes and petroleum steel pipes used in hydraulic systems, also known as honing pipes. Cold-drawn or cold-rolled seamless steel pipes also include hydraulic steel pipes.Читати далі -
Який припуск на обробку безшовних труб?
Щоб зрозуміти, скільки міліметрів зазвичай залишають припуск на обробку безшовних труб, необхідно спочатку розібратися в діапазоні допуску на розміри самого виробу. Допуск на розмір виробу відноситься до допустимого діапазону відхилення фактичного розміру виробу.Читати далі -
Tensile strength of stainless steel seamless pipes
There are many factors that affect the drawing force during the drawing process of stainless steel seamless pipes. According to research, some of these factors are beneficial to the drawing process. Conversely, other factors can make stretching more difficult.Читати далі -
Cast iron pipe vs Carbon steel pipe
Carbon steel pipes & tubes also called CS pipes, are made of steel ingots or solid round steels through perforation into capillary tubes, which are then hot-rolled, cold-rolled or cold-drawn. Carbon steel pipe plays an important role in my country's steel pipe industry.Читати далі
