Advantages of I-beams

Advantages of I-beams

I-shaped beams are hollow web members. For high-strength materials, hollow web members are better than solid web members in terms of weight, material, and labor saving. This cross-sectional design mainly uses the flange farthest from the centroid to resist bending moments (because the farther the flange is, the greater the moment of inertia), and mainly uses the web to resist shear. As for the inconvenience in making it, it can be solved by factory or molding. Saving materials, labor, and time is efficiency.

How are stainless steel pipes classified?

How are stainless steel pipes classified?

Stainless steel pipes are divided into ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, stainless steel pipes, as well as bimetallic composite pipes, coated and coated pipes to save precious metals and meet special requirements. There are various types and uses of stainless steel pipes, with varying technical requirements and production methods. The current production of steel pipes has an outer diameter range of 0.1-450mm and a wall thickness range of 0.01-250mm. To distinguish its characteristics, steel pipes are usually classified according to the following method.

How to determine the specifications of channel steel

How to determine the specifications of channel steel

The delivery length of channel steel can be divided into two types: fixed length and double length, and the tolerance value shall be specified in the corresponding standards. The length selection range of domestic channel steel is divided into three types based on different specifications: 5-12m, 5-19m, and 6-19m. The length selection range of imported channel steel is generally 6-15m.

Preparation method of carbon steel pipe

Preparation method of carbon steel pipe

The raw material of carbon steel pipe is round tube blank, which needs to be cut and processed by a cutting machine to form a billet with a length of about 1 meter, and then sent to the furnace for heating through a conveyor belt. The billet is fed into the furnace for heating, with a temperature of approximately 1200 degrees Celsius.
