Key Indicators and Grades of Seamless Steel Pipe Accuracy
Jane The precision of seamless steel pipe refers to the degree of control over the deviation of the outer diameter, inner diameter, wall thickness, length and other dimensions of the steel pipe during the manufacturing process. High-precision seamless steel pipes require strict control of relevant parameters during processing and manufacturing to meet the needs of specific applications.…
The Importance of Non-destructive Testing to the Quality of Non-standard SMLS Pipes
Jane Non-destructive testing (NDT) is crucial to ensuring the quality of non-standard smls pipes(seamless steel pipe), even more important than for standard seamless steel pipes. This is because the particularity of non-standard steel pipes determines that their quality control faces greater challenges. Quality risks of non-standard smls steel pipes Large dimensional deviation: Since it is non-standard customization, the dimensional…
What are the Requirements for Welding Hot Rolled Seamless Steel Pipes?
Jane Hot-rolled seamless steel pipe is one of the important production types of seamless steel pipe. It is made of round steel billet as raw material, after high temperature heating, through perforation, rolling and other processes. Because the metal is in a thermoplastic state during production, internal defects can be eliminated, making the pipe structure denser. Hot…
API 5L Grade B Seamless Steel Pipe
Jane API 5L Grade B seamless steel pipe is a kind of seamless steel pipe widely used in the oil and gas industry. API 5L is a standard developed by the American Petroleum Institute (API) to regulate pipeline steel pipes. The “L” in “5L” stands for pipeline (Line). The standard covers seamless and welded steel pipes, with Grade…
How to Improve the International Competitiveness of Seamless Tubes?
Jane To enhance the international market competitiveness of the seamless tube industry involves strategic adjustments and technological innovations in many aspects. With the increasing demand for high-quality steel pipe products in the global market, especially in the oil, natural gas, chemical, energy and other industries, the requirements for seamless steel tube have gradually increased. The industry must…
Sandblasting of Seamless Tubes: Definition, Purpose and Process
Jane In industrial scenarios such as oil pipelines, chemical equipment, and building steel structures, seamless tubes have become key materials due to their high strength and corrosion resistance. But did you know that these steel pipes often need to undergo a crucial “beauty process” before they are put into use – sandblasting. This seemingly simple surface treatment technology…
How is the Wear-resistant layer of wear-resistant SMLS Pipe Manufactured?
Jane The wear-resistant layer of wear-resistant smls pipe is manufactured by a variety of technical means, the purpose is to enhance the wear resistance of the steel pipe so that it can be used for a long time in a high wear environment. Several common methods for manufacturing the wear-resistant layer of wear-resistant smls pipe are carefully summarized:…
