coml Founded in 2014 with a registered capital of 30million yuan, it is an integrated steel procurement service provider based in Changsha and serving the whole country
It is committed to providing integrated steel procurement services for domestic steel purchasers
Shengshida has successively reached strategic cooperation with a number of domestic key projects, and successfully completed projects such as Shanghai Kunming high speed railway, Huaneng Power Plant, Changsha Nanhu road tunnel, Changsha Xiangfu road bridge, Changsha fuyuanxi bridge, etc

Spiral steel pipe is a kind of spiral seam steel pipe, which is made of strip steel coil as raw material, often formed by warm extrusion, and welded by automatic double wire double-sided submerged arc welding process
The spiral steel pipe sends the strip steel to the welded pipe unit
After rolling by multiple rollers, the strip steel is gradually rolled up to form a circular tube blank with open gap
Adjust the reduction amount of the extrusion roller to control the weld gap at 1~3mm and make both ends of the weld joint flush

 
Shengshida spiral steel pipe uses:
Spiral steel pipe is mainly used in tap water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation and urban construction
It is one of the 20 key products developed in China

For liquid transportation: water supply, drainage, sewage treatment works, mud transportation, ocean water transportation

For gas transmission: coal gas, steam, liquefied petroleum gas

For structure: as pile driving pipe and bridge; Pipes for wharfs, roads, building structures, offshore piling pipes, etc

 
Process characteristics of shengshida spiral steel pipe:
1
During the forming process, the deformation of the steel plate is uniform, the residual stress is small, and the surface is not scratched
The processed spiral steel pipe has greater flexibility in the size range of diameter and wall thickness
It has good advantages in the production of high-grade thick wall pipe and medium and small-diameter thick wall pipe, and can meet more requirements of users in the specification of spiral steel pipe

2
With the advanced double-sided submerged arc welding process, the welding can be realized at the appropriate position, and it is not easy to have defects such as misalignment, welding deviation and incomplete penetration, and it is easy to control the welding quality

3
The quality of steel pipes is checked, so that the whole process of steel pipe production is under effective detection and monitoring, and the product quality is effectively guaranteed

4
The equipment has the function of networking with the computer data acquisition system to realize real-time data transmission
The technical parameters in the production process are monitored by the central control room
