Seamless Steel Pipe Boiler Tube

Description

Boiler tube is a kind of seamless tube. The manufacturing method is the same as seamless pipe, but there are strict requirements for the steel used in the manufacture of steel pipes. According to the use of temperature is divided into general boiler tube and high pressure boiler tube two kinds.

The mechanical properties of boiler tubes are important indicators to ensure the final service performance of steel (mechanical properties), which depends on the chemical composition of steel and heat treatment system. In the steel pipe standard, according to different requirements, tensile properties (tensile strength, yield strength or yield point, elongation) and hardness, toughness indicators, as well as high and low temperature properties required by users.

Uses of packaging in the steel industry

Protective function

- Prevent steel products from physical damage, such as collision, scratching and extrusion, during transport, storage and handling to avoid affecting the quality and appearance of the products.

- Insulate from external environmental factors, such as humid air, rain, dust, etc., to reduce the risk of rust and corrosion of steel and ensure the performance and service life of the products.

Wooden box packaging

- Use: Mainly used to protect some irregular shape, easy to damage or high requirements for packaging of steel products, such as precision parts and components.

- Specific description: the wooden box is made of thick wooden boards, and cushioning materials, such as foam, air cushion, etc., may be added inside to reduce the impact of vibration and collision on the product.

Anti-rust paper packaging

- Purpose: To prevent rust and corrosion of steel products, especially suitable for storage or transportation in a humid environment.

- Specific description: anti-rust paper usually contains rust inhibitors, can be in contact with the metal surface to form a protective film, blocking the erosion of moisture and oxygen.

Plastic film packaging

- Purpose: To provide basic protection against dust and moisture, commonly used for small steel products.

- Specific description: plastic film has a certain degree of flexibility and sealing, can be tightly wrapped in the product surface, effectively isolate the external environment.

Pallet packaging

- Purpose: To facilitate the stacking and handling of steel products, and improve logistics efficiency.

- Specific description: The pallet is usually made of wood or plastic, the steel products are placed on the pallet, and then the forklift and other tools can be used for handling and loading and unloading.

Factory container packing

- Purpose: It is used for mass transportation of iron and steel products, to protect the products and improve the utilization rate of transportation space.

- Specific description: Containers have a strong structure and good sealing, and can adapt to long-distance transportation and the conversion of multiple modes of transportation.

Anti-rust oil coating packaging

- Purpose: To form a layer of antirust oil film on the surface of steel and enhance the antirust ability.

- Specific description: evenly cover the steel surface with anti-rust oil by brushing or soaking to form a durable protective layer.

Metal Corner Protection Packaging

- Purpose: To protect the corners and edges of steel products from damage during handling and transportation.

- Specific description: Metal corner guards are usually installed on the corners of products, using welding, bolting and other methods to increase the strength and impact resistance of the corners.
