ERW pipe forming mill and flying cutoff machine

Shijiazhuang Zhongtai Pipe Technology Development Co., Ltd. is established in 2000,locates in Shijiazhuang, the capital city of Hebei Province. Adjacent to Beijing City,we are endowed with convenient transportation and geographical condition.

We combine development, production, sales with service, our technicians work stably with precise working style. The production line adopts assembly line method with exquisite technology, well- found inspection equipment for  production. In recent years, our company has become a considerably scaled manufacturer of welded pipe production line in China. Our products are sold all over the country. We served equipments with high quality to some domestic large scale enterprises such as Steel Pipe Mill Of Shengli Oil Field, Jiangsu Sujia Group, Kunming Steel Group, Nanjing Wanrun etc.Our products are exported to Southeast Asia as well. We succeeded in developing complete plants with advanced international standards such as H.F. straight welded pipe prodution line for φ20-φ610, multi-functional cold rolled section steel welded pipe production line LW100-LW2200, slitting line ZJ100-ZJ2200 etc. We take the fancy within the industry and new and old customers because of excellent production quality.

ERW rectangle  GI/galvanized steel pipe making machine is specialized equipment to produce high frequency straight seam welded pipes for structural pipe and industrial pipe . These ranges can be adjusted according to customers’ need .Through optimization design, best materials choice, and accurately fabrication and rolls, the whole line can be reached high precision and high speed. Within suitable range of pipe diameter and wall thickness, pipe production speed can be adjusted.

Square to Square Welded Pipe Production Line

This way is to directly roll the steel strip and bend it to square & rectangular shape, then weld to finish the formation.

Characteristics & Advantages:

1)Compared with roun to square forming method,this method can make:bettershape of angles for crosssection,smaller semidiamter of inner arcis,flatter brim,regular outlook;

2)Low load for the whole line,especially in the sizing part;

3)2.4-3% strip width sbrinkage than round square forming method,so that to save raw materials;

4)By advance multi-point bending,avoiding the axial force and side abrasion,reducing the forming step and ensuring theq- uality,meanwhile reducing power wastage and roll abrasion; 5)By combined rolls,one set can be used to produce lots of sq- uare & rectangular pipes for different

specifications.This can decrease the storage of rolls,lower 80% roll cost,fast the bankroll turnover, shorten developing time for new lines.

This steel tube making machine can produce different kind of steel pipes:

1. Water pipe
2. Heating pipe
3. Low-pressure process pipeline
4. Low pressure fire fighting pipeline
5. Sewage Pipes
6. Steel Scaffolding Pipe
7. Wire and cable protection pipe
8. Structural support Steel Pipe
9. Industrial Steel Pipes
10. Decoration Pipe
11. Oil & Gas Pipes
