SMLS pipes and welded pipes serve different roles in industry:

Seamless pipes: higher cost but superior strength, uniformity, and high-pressure suitability
Welded pipes: tiết kiệm chi phí, suitable for low to medium-pressure applications

Both types are available in standard nominal sizes, độ dày của tường, và độ dài, making them adaptable for a wide range of công nghiệp, cấu trúc, và ứng dụng cơ khí.

Sự miêu tả

SMLS Pipe, hoặc Seamless Stainless Steel Pipe, is manufactured from solid billets through hot piercing and rolling without any welded seam.
Nó được sử dụng rộng rãi trong high-pressure, nhiệt độ cao, and corrosive environments, such as chemical processing, oil and gas, power plants, and mechanical systems.

Welded stainless steel pipes are made by rolling and welding flat steel plates, which creates a seam along the pipe. Both types have advantages depending on ứng dụng, áp lực , and budget.

Seamless vs Welded Stainless Steel Pipe

Tính năng	Ống nước liền mạch (SMLS)	Ống hàn
Manufacturing Method	Hot piercing & rolling from solid billet	Rolled plate welded along seam
Wall Consistency	Highly uniform	Slight variation near weld
Pressure Resistance	High – suitable for high-pressure systems	Moderate – depends on weld quality
Chống ăn mòn	Excellent – no weld seam to corrode	Good – weld may require extra treatment
Độ chính xác kích thước	Cao	Vừa phải
Trị giá	Cao hơn	Thấp hơn
Ứng dụng điển hình	High-pressure, hóa chất, hóa dầu, phát điện	Low to medium-pressure piping, water systems, structural tubes

Bản tóm tắt: Seamless pipes are preferred for critical systems requiring sức mạnh, uniformity, and high-pressure performance, while welded pipes are cost-effective for low-pressure or non-critical applications.
