Product Description

Our company proudly presents the Reinforced Spiral Welded Steel Pipe, an innovative solution designed specifically for underground gas drainage in coal mines. This state-of-the-art pipe boasts remarkable advantages over traditional gas drainage steel pipes, including lightweight construction, exceptional ring stiffness, and superior corrosion resistance. These attributes not only enhance performance but also significantly reduce the total construction costs for mining operations. Over the years, our product has garnered widespread acclaim and trust from our customers, becoming a staple in their operations. Through meticulous structural design, we've enhanced the pipe's negative pressure resistance and optimized the wall thickness using unique biting structural reinforcement.
To cater to varying customer requirements, our reinforced spiral welded steel pipe features a tri-layer anti-corrosion structure: fused epoxy powder coating, hot dip zinc, and stainless steel. This versatile product can be manufactured with a maximum diameter of DN1000mm and a wall thickness ranging from 1.5mm to 3.5mm, depending on the specific model. These options ensure that our solution can meet the diverse needs of our clients while delivering unparalleled durability and performance.

Connection Method 

The spiral welded steel pipe primarily utilizes a flange connection method. Specifically designed with flange sockets, the product can be securely joined at both ends by adding bolts, ensuring a robust and reliable connection.  

Product Features

Light Weight

Compared to traditional steel pipes of the same specification, this pipeline offers a remarkable reduction in weight by 50% - 150%. Its lightweight nature significantly cuts down on labor intensity during construction.  

Corrosion Preventive
Choose from fused epoxy powder coating, hot-dip zinc, or stainless steel options to ensure unparalleled corrosion resistance and extend the service life of the pipe.

Negative Pressure Resistance
Engineered to meet stringent negative pressure performance requirements for gas drainage, this pipe withstands up to -0.097MPa pressure for 100 hours without any suction or deformation.  

Low Operating Noise
Thanks to its flat inner wall structure, this pipe operates with notably low noise levels, providing a smooth and quiet performance during normal operations.

Strong Adhesion
Utilizing corrosion-resistant materials compliant with national standards, the pipe's coating adheres strongly, eliminating issues of peeling or detachment during use.  

Product Advantages

Crafted from cold-rolled or stainless steel strips, these pipes undergo multiple forming processes, including spiral nibble molding and automatic welding. The smooth inner wall and reinforced outer wall, built with a four-layer nibbling structure, enhance both weld strength and impact resistance, thanks to 45° angle welds.
Named 'occlusal steel pipe' due to its unique occlusal structure, this product features a reinforcing bar-type outer wall, also known as reinforcing bar spiral welded corrugated steel pipe.
