Product Details
Large diameter thin wall spiral welded pipe equipment
Product Introduction
Large diameter and thin wall spiral welded pipe equipment is specially used to produce spiral welded pipe with large diameter but thin wall thickness. This kind of welded pipe is usually used in the field of conveying low pressure fluid, ventilation pipe, building structure and so on. Due to the thin wall of the welded pipe, special equipment and processes are required to ensure the welding quality and the overall strength of the product. The internal support is increased to avoid the deformation of the pipeline due to its own weight, and the price of the equipment is greatly reduced compared with the standard large-diameter spiral pipe unit.
Application areas
Large diameter thin-walled spiral welded pipe is widely used in the following fields due to its light weight, moderate strength and low manufacturing cost:
• Low pressure fluid transport: such as water, air and other transport pipeline.
Building structure: used for building support, enclosure structure, etc.
• Ventilation and exhaust systems: Piping used for ventilation and exhaust systems in industrial and commercial buildings.

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.
