The difference in market price between thin-walled seamless steel pipes and thick-walled seamless steel pipes mainly depends on the production process, material cost, application field and demand. The following are their main differences in price and transportation:

1. Market price difference
Thin-walled seamless steel pipe:

Lower cost: Due to the thin wall thickness, less raw materials are used, and the manufacturing cost is relatively low.

Widely used: Mainly used in occasions with low requirements for strength and pressure resistance, such as construction, decoration, fluid transportation, etc., with large market demand.

Small price fluctuations: Generally, the price is stable and is greatly affected by the steel market.

Thick-walled seamless steel pipe:

Higher cost: The wall thickness is large, more raw materials are used, and the production process is complex, resulting in higher costs.

High performance requirements: Commonly used in fields with high pressure and high structural strength requirements, such as mechanical equipment, petrochemicals, boilers, etc., with high requirements for compressive strength and corrosion resistance.

High price and large fluctuations: Due to the rigid demand for thick-walled steel pipes in specific fields, the price fluctuates relatively greatly, especially when the price of steel raw materials rises.
2. Transportation precautions
Thin-walled seamless steel pipe:

Easy to deform: Due to the thin wall of the pipe, it is easy to be deformed by external forces during transportation, especially when bundling and stacking.
Prevent scratches: The surface of thin-walled pipes is easily damaged, and appropriate protective measures should be taken, such as covering the surface with plastic cloth or other protective materials.
Stable bundling: It is necessary to use soft belts or special steel belts to bundle to avoid deformation of the pipe body due to excessive tightening.
Thick-walled seamless steel pipe:

Heavy weight: Thick-walled steel pipes are heavy, and large lifting equipment is required during transportation, and the transportation tools need to have sufficient carrying capacity.
Stable stacking: Due to the heavy weight of steel pipes, balance and stability should be considered during stacking to avoid rolling or tipping, especially during transportation to prevent sliding or collision.
Transport safety: During long-distance transportation, special attention should be paid to tools such as anti-slip pads and support blocks between steel pipes to avoid damage caused by friction and impact.
The price of thin-walled seamless steel pipes is relatively low, but attention should be paid to preventing deformation and surface damage during transportation; while the price of thick-walled seamless steel pipes is higher, and special attention should be paid to safety, stability and weight management during transportation. However, seamless steel pipes with special materials and specifications still need to be actually evaluated.
Sanonpipe main seamless steel pipes include boiler pipes, fertilizer pipes, oil pipes, and structural pipes.
