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.더 읽어보기 -
탄소강관 도장공법 비교
탄소강관 도장이란 강관의 외관을 더욱 아름답게 하거나 보호성을 높이기 위해 강관의 표면에 브러싱, 스프레이 등의 방법으로 도료를 칠하는 것을 말합니다. 코팅은 건축 공학, 자동차 수리, 가정 장식 및 기타 분야에 사용될 수 있습니다. 코팅이 물체 표면에 단단히 부착될 수 있도록 페인팅하기 전에 물체의 표면을 완전히 청소하고 다듬어야 합니다.더 읽어보기 -
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.더 읽어보기 -
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.더 읽어보기 -
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:더 읽어보기 -
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.더 읽어보기 -
이음매없는 파이프의 가공 허용량은 얼마입니까?
일반적으로 무봉관의 가공 공차가 몇 밀리미터 정도 남는지 이해하려면 먼저 제품 자체의 치수 공차 범위를 이해해야 합니다. 제품의 치수 허용차란 제품의 실제 크기와 허용되는 편차 범위를 말합니다.더 읽어보기 -
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.더 읽어보기 -
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.더 읽어보기
