Definition of batch number and heat number:
The seamless steel pipe (smls pipe) heat number refers to the heat number used to produce seamless steel pipes. The heat number is generally compiled by the manufacturer. Its location and coding method vary from steel mill to steel mill. It is used to track and control the production process of the steel pipe and detect its quality.
The batch number refers to the serial number of the same production batch, refers to the manufacturing date and batch of the product, and is mainly used to trace the production process and quality management of steel pipes.
The role of batch number and heat number:
The batch number and heat number of steel pipes are the identification methods adopted by steel pipe manufacturers to manage the production process, control quality, identify steel pipes, etc. The batch number and heat number are determined during the steel pipe production process and are used throughout the production process until the steel pipe is delivered to the customer. Therefore, identifying the batch number and furnace number can help us understand the production process and related information of steel pipes, and help steel pipe users make reasonable material selection and safe use.
The difference between seamless steel pipe heat number and batch number:
Seamless steel pipe batch numbers and heat numbers have many similarities, but there are some differences between them. The steel pipe batch number is an identification number that distinguishes different batches of steel pipes, while the furnace number is an identification number that indicates the furnace used to manufacture the same batch of steel pipes. It can be said that the furnace number is an important piece of information about the batch, and the batch number also contains information about the furnace number.
The heat number is an important parameter in steel production. Different heat numbers have different product quality. The furnace number can help consumers understand the production history of the product and thereby determine the quality and performance of the product. Generally speaking, for the same batch of seamless steel pipes, if the product performance of different heat numbers is greatly different, the product with better heat number should be selected.
The batch number refers to the product serial number of the same production batch. The product batch number is compiled by the manufacturer and is a unique identifier to distinguish different production batches. Batch numbers can help manufacturers understand the quality status of products and conduct traceability management of products. When consumers purchase products, they can also learn about the production batch of the product based on the batch number, and query the production date, production process and other information of the product based on the production batch number provided by the manufacturer.
What is the purpose of numbering?
The purpose of numbering is, firstly, to facilitate the arrangement of production; secondly, to facilitate quality control, and take back products with the same heat number or batch number when quality problems are found; thirdly, when an accident occurs in the hands of the end user, the production information at that time can be traced according to these marks , to facilitate the identification of whether there is a quality problem in the material.
How to identify the grade and manufacturer of steel pipes based on the batch number and heat number?
Important information such as the grade and manufacturer of the steel pipe can be identified through the steel pipe batch number and furnace number. Generally speaking, relevant production information will be marked next to the batch number and heat number, such as the specifications, grade, production date, manufacturer, etc. of the steel pipe. Here's how to identify it:
1. Steel pipe grade: You can check the steel pipe manufacturer's official website through the batch number and furnace number, or ask the relevant department for verification.
2. Manufacturer: You can also check the official website through the batch number and heat number.
3. Steel pipe specifications: Usually the specifications of the steel pipe are included in the information marked with the batch number and heat number.
4. Production date: Generally, it will also be marked next to the batch number and furnace number.
Conclusion:
The seamless steel pipe heat number and batch number are unique identifiers of the product, which can help consumers understand the production and quality status of the product. The heat number of seamless steel pipes is mainly used to determine the quality and performance of the product, while the batch number is mainly used for production management and product traceability. When consumers purchase products, they can use these two identifiers to understand the production and quality of the product and choose products with better quality.
Tips: ASTM A53 covers seamless and welded steel pipe with nominal wall thickness. The surface condition is usually black and hot-dipped galvanized. ASTM A53 ERW steel pipe is a typical carbon steel pipe. It is largely used to convey fluids at low / medium pressures such as oil, gas, steam, water, air and also for mechanical applications.
