Embodiment Construction

[0014] Such as figure 1 As shown, a method for manufacturing a large steel pipe includes: 1) providing a steel plate 5; 2) pulling the steel plate 5 into a welding cavity 8 with an upper welding wheel 6 and a lower welding wheel 7; 3) continuously pulling the steel plate 5 for welding Large-scale cylindrical steel pipe 1. The upper welding wheel 6 welds the steel plate 1 at the joint of the steel plate 5. The lower welding wheel 7 welds the steel plate 5 at the joint of the steel plate 5. The upper welding wheel 6 and the lower welding wheel 7 are arranged symmetrically. The upper welding wheel 6 is arranged inside the steel plate 5. The 7 lower welding wheels are arranged on the outside of the steel plate 5. The steel plate 5 is pulled by mechanical equipment.

[0015] Such as figure 2 Shown as figure 1 The large-scale steel pipe 1 produced by the method of manufacturing the large-scale steel pipe shown. The large steel pipe 1 includes: a cylindrical tube, and paint 3 spra...

Abstract

The invention discloses a manufacturing method of a large-scale steel pipe. The manufacturing method comprises the following steps of 1, providing a steel plate, 2, drawing the steel plate into a welding chamber with an upper welding wheel and a lower welding wheel, and 3, welding the steel plate into a cylindrical large-scale steel pipe with continual pulling. Through the upper welding wheel and the lower welding wheel arranged at an upper side and a lower side of the steel plate, the steel plate can be welded into the cylindrical large-scale steel pipe. The manufacturing method is convenient for welding automation and large-scale production.

Description

【Technical Field】 [0001] The invention relates to a method for manufacturing large steel pipes. 【Background technique】 [0002] Large steel pipes can be used in underground pipelines, oil, natural gas, steam heating, hydropower stations, sewage treatment plants, thermal power plants, water supply and drainage, etc. Large-scale steel pipes are used in these extremely harsh conditions, and the outer side walls of the large-scale steel pipes will be corroded due to various reasons. The existing designs for the manufacture of large steel pipes have extremely low efficiency through manual welding, long production hours and high manufacturing costs. [0003] In view of the shortcomings of the above technology, it is necessary to improve the design. [Content of the invention] [0004] The technical problem to be solved by the present invention is to provide a method for manufacturing a large steel pipe, which is convenient for welding automation. [0005] In order to solve the above techn...
