Welding production line of alloy furnace tube and tube bundle

Abstract

The invention discloses a welding production line of an alloy furnace tube and a tube bundle, and is characterized by comprising an automatic welding area, an automatic welding coloring area, a manmade argon arc welding area, an alignment area, a coloring area, a grinding and root welding area and an X-ray transport area, which are arranged at a first row from left to right in sequence, and an X-ray area, a manmade argon arc welding area, a straight tube coloring area, a water pressure test area, a furnace tube product drilling area, a finished product checkout packaging area and a finished product consignment, which are arranged at a second row from left to right, wherein a furnace tube transport area used for the tube bundle is arranged in the finished product checkout packaging area, a tube bundle transport device, a tube bundle welding area, a tube bundle coloring area and a tube bundle water pressure test area are arranged at a third row below the furnace tube transport area from right to left, and a sand blasting house, a packaging area and a consignment area are arranged at a fourth row from left to right. The welding production line, provided by the invention, has the advantages of compact structure between process devices and small plant area; the furnace tube flows in each checkout process and detection device, the product quality is controlled in an ordered manner; the product quality of the furnace tube is ensured to be stable and reliable, and the welding production line is high in production efficiency.

Description

Technical field: [0001] The invention relates to a welding production line of an alloy furnace tube and a tube bar. Through furnace tube blank casting, machining, and related production processes and inspection procedures in the welding production line, qualified furnace tubes and tube bar products are obtained. Background technique: [0002] Petrochemical furnace tubes and tube row, which are mainly used in ethylene cracking furnaces and hydrogen conversion furnaces in the petrochemical industry. [0003] The ethylene cracking furnace is the heart of the raw material gas for ethylene products produced from petroleum gas. Ethylene products are chemical raw materials related to people's basic necessities of life. The development level of ethylene products is the main indicator of the development level of a country's petrochemical industry. [0004] The hydrogen production conversion furnace uses petroleum gas to produce hydrogen, which is used to synthesize ammonia to make ...

Problems solved by technology

In this way, it is easy to cause the quality of the furnace tube and its tube bank to be unqualified due to the difference in the requirements of the furnace tube and its tube bank and other similar products, the difference in the production process, the difference in the inspection procedure and the requirements.

[0009] The second category: The production scale is not large. Although it is a professional manufacturer of high-temperature-resistant alloy furnace tubes and tube rows for petrochemical use, the furnace tube production equipment is outdated, the testing equipment is backward and incomplete, and the layout of the production process and testing process is not good. Reasonable

The quality of the furnace tubes produced by these manufacturers is unstable and unreliable

[0010] The third category: The production has a certain scale, and it is also a professional manufacturer specializing in the production of high-temperature alloy furnace tubes and tube rows for petrochemical use. The furnace tube production equipment and testing equipment are complete, but the layout of the production process and testing process is unreasonable. and inspection procedures are chaotic, relying on driving to run the products of each production and inspection procedure

The quality of furnace tubes produced by these manufacturers is still unstable
