• Alloy Steel:Used for more corrosive environments or higher temperature applications,such as transporting chemicals or hot water.

• Stainless Steel:Provides excellent corrosion resistance for transporting potable water,chemicals,and food-grade liquids.

Surface Finish:

• Roughness(Ra):The surface roughness can affect the flow characteristics and should be specified according to the application requirements.

• Coatings:May include internal and external coatings for enhanced corrosion protection,such as epoxy,fusion-bonded epoxy(FBE),or polyurethane.

Pressure Rating:

• PSI(Pounds per Square Inch):Indicates the maximum pressure the pipe can withstand.

• Bar:A metric unit of pressure,also used to specify the pressure rating.

Temperature Range:

• Operating Temperature:The range of temperatures within which the pipe can safely operate without degradation of material properties.

• Expansion and Contraction:Consideration of thermal expansion and contraction is crucial for proper installation and operation.

Size Tolerances:

• Outer Diameter(OD)Tolerances:Specify the acceptable variation in the outer diameter of the pipe.

• Wall Thickness Tolerances:Ensure the pipe has the required wall thickness for pressure containment.

Weight per Unit Length:

• Calculated based on the volume of steel per unit length and the density of the material.

Elongation:

• The percentage of elongation at break,indicating the ductility of the material.

Impact Resistance:

• Measured in terms of Charpy V-notch(CVN)or Izod impact tests,indicating the material's ability to withstand impact without fracturing.

Flammability and Smoke Emission:

Packaging & Delivery

Performance

1. Mechanical properties

High strength: seamless pipes have no welds, and the overall strength is higher than that of welded pipes, suitable for high pressure and impact loads;

Fatigue resistance: not easy to crack under cyclic loads, suitable for vibration environments (such as mechanical transmission pipes).

2. Corrosion resistance

Stainless steel material: 304/316L seamless pipes are resistant to acid, alkali and salt corrosion and are widely used in chemical and marine engineering;

Surface treatment: galvanizing (Zn), epoxy resin coating (EP), and polyethylene lining (PE) can further enhance the corrosion resistance.

3. Process performance

Weldability: Carbon steel and low alloy steel seamless pipes can be connected by welding, and stainless steel pipes require special welding materials;

Processability: Can be bent, expanded, reduced in diameter and other processing (cold-rolled pipes are easier to form).

4. Sealing

The weld-free design is suitable for scenarios with high sealing requirements (such as gas pipelines and hydraulic systems).

FAQ

1. Q: What is the difference between seamless pipes and welded pipes?

5. Q: How to prevent rust during transportation of seamless pipes?

Answer:

Short-term transportation: can be naked in dry environment, and covered with waterproof cloth in humid environment;

Long-term storage: stored in a dry warehouse, ≥20cm from the ground, regularly check the surface rust, and re-oil if necessary.
