Product Details





If you have ever referred  to the ASTM (American Society for Testing and Materials) standard documents used for steel design and  construction, you’ll notice that ASTM A53 steel pipe designations are different than ASTM A500 round hollow structural sections and they are  manufactured to meet different standards.

Influence on flow characteristics of conveying medium

The pressure drop in the conveying pipeline is directly proportional to the length of the pipe, the coefficient of fluid viscosity, the coefficient of fluid velocity, and the coefficient of fluid resistance, and inversely proportional to the diameter of the pipe.The fluid resistance coefficient is related to both the Reynolds number and the roughness of the inner surface of the pipe.It has been found that the roughness of the inner surface of the pipe has ten times more effect than the area of local uplift, such as spiral or longitudinal welds, or even inner ring welds.


Production and management


Spiral welded steel pipe production can reflect the advantages of high quality and efficiency.The production capacity of a spiral welded pipe unit is equivalent to 5-8 sets of straight welded pipe equipment. How to make multiple production lines of coil pipe equipment meet the same production standard, that is, to produce according to the unified production process specification and quality assurance system to meet the welding quality requirements and pipe manufacturing level will be a heavy work.


Multiple production potential ratio increases the quantity of engineering management and quality supervision.Many sets of straight seam pipe unit and the corresponding welding equipment, the operating personnel operating skills, quality awareness, the differences between the distribution point and control program will lead to the production management, schedule, check acceptance, delivery, coordination and so on many difficulties, easily to manage and coordinate the hectic and the manufacturer and the quality of the construction unit shuffle.


Quality assurance



According to the production standard of spiral welded pipe, the main inspection/control items of spiral welded pipe include:Dimensions: outside diameter, wall thickness, ovality, bending, tube end perpendicularity,Length appearance quality: weld residual height, wrong side, steel surface, lamination, inclusion, weld defect determinationChemical compositionWelding joint tensile testHydrostatic testAcid corrosion testNondestructive inspectionHowever, there is no corresponding production standard for straight welded pipe.
