Product Details
Spiral welded pipe Machine
Product Introduction
Spiral welded pipe Machine is a steel pipe formed by rolling low-carbon carbon structural steel or low-alloy structural steel strip into a tube blank by a forming machine according to a certain forming angle, and then welding the spiral pipe seam with a submerged arc welding machine. The advantage is that a narrow strip can be used to produce large diameter steel pipe.
use of spiral welded pipe:
• For liquid transportation: water supply and drainage;
• For gas transmission: gas, steam, liquefied petroleum gas;
For structural use: pile driving pipe, bridge, wharf, road, building structure pipe, etc.
Process flow:
Roll-up → uncoiling → leveling → shearing butt welding → disc shearing → edge milling → delivery machine → pre-bending guide plate → forming → internal welding → external welding → cutting off → pulling out → flat head chamfering → hydraulic test → finished product collection
The spiral welded pipe production line is a mature unit with very competitive and technical characteristics in Huaye. The product specifications range from Φ25mm to 4000 Φmm, and are divided into general units and special customized units.
Many domestic firsts and domestic firsts fully demonstrate the strong technological advantages of Huaye and the research and development capabilities of many cutting-edge technologies.

Shipping
Although the welded pipe equipment itself has a large volume and weight, it is basically modular. We will try our best to design each module into a standard container.
But there are always some special parts, no matter how to change the design also exceed the volume size of the container. At this time we will use frame containers or open top containers.
If there are too many overweight or oversized parts, we will also choose bulk carriers for shipment.
