Raw material supply 1 Stainless steel material selection: the main raw material of large diameter stainless steel seamless pipe is stainless steel, whose main components are iron, chromium, nickel and other alloying elements. Reasonable raw material selection is the key to ensure product quality. 2 Supplier selection: as a manufacturer, distributor, wholesaler or supplier, it is very important to choose reliable raw material suppliers. As a stainless steel pipe supplier with many years of experience, Sentway has won market recognition for its stable supply ability and high quality products.

This article contains stainless steel tube processing methods, common processing techniques, raw material selection, and processing considerations. Understanding these basic knowledge will help better stainless steel tube processing. Stainless steel tube processing methods

Pickling Surface Treatment Methods for Stainless Steel There are generally two methods for pickling treatment: chemical and electrolytic. For stainless steel pipes, only chemical pickling is used for corrosion prevention. This method can remove oxide scale, rust, and old coatings. Sometimes it is used as a post-treatment after sandblasting. Although chemical cleaning can achieve a certain level of cleanliness and roughness, it produces shallow anchor patterns and may cause environmental pollution.

The gray spots of different sizes on the surface of galvanized seamless steel pipes are the color difference of galvanizing, which is a problem in the current galvanizing industry. It is mainly related to the trace elements contained in the steel pipe itself and the components in the zinc bath. The stains do not affect the anti-corrosion performance of the steel pipe, but only differ in appearance. On the surface of each galvanized seamless steel pipe, there are gradually obvious raised marks, which are all zinc. The galvanized seamless steel pipe is taken out of the zinc pot, and the zinc liquid flows down the pipe wall and then cools and solidifies.

The promotion and application of precision seamless pipes is of great significance to saving steel, improving processing efficiency, and reducing processing procedures or equipment investment. It can save costs and processing time, increase output and material utilization, and at the same time help improve product quality, reduce costs, and improve economic benefits. Generally, precision seamless pipes are used in industries with high precision requirements, while seamless pipes are mostly used in industries without precision requirements. After all, the price of precision seamless pipes of the same specifications is higher than that of seamless pipes.

Hot-rolled seamless steel pipe inspection: including the inspection of medium and low pressure boiler steel pipes, general performance steel pipes, high pressure boiler steel pipes, stainless steel pipes, alloy steel pipes, geological steel pipes, petroleum cracking steel pipes and other hot-rolled seamless steel pipes. Seamless steel pipe cold-rolled seamless steel pipe inspection: including general structural steel pipes and seamless steel pipes for mechanical structures, seamless pipes for high pressure boilers, seamless pipes for low pressure boilers, seamless pipes for cold drawn or cold precision steel pipes, seamless pipes for transmission fluids, seamless pipes for geological drilling, seamless pipes for fertilizers, hydraulic cylinder precision inner diameter seamless pipes, seamless pipes for fertilizers, petroleum cracking pipes, seamless pipes for ships, various alloy cold-rolled seamless steel pipes for inspection

What are the inspection items for American standard seamless pipes? There are many quality inspection items for American seamless steel pipes, mainly including physical and chemical properties, composition detection, size and process performance. This article takes the ASTM A450/A450M standard for steel pipes exported to the American standard as an example. Each requirement in this standard is activated by a total of 34 ASTM steel pipe standards, including ordinary seamless splicing and welded steel pipes, as well as American standard seamless pipes for steam boilers, ironmaking, sanitation, natural gas, and natural gas water supply pipelines. In the standard, each requirement is divided into mandatory and non-mandatory. Non-mandatory requirements are mainly inspected through agreements between supply and demand parties.

Anti-Corrosion Seamless Pipeline offer enhanced durability, reduced maintenance costs, and increased safety in various applications.

Make sure the seamless steel pipe you choose meets the highest standards by recognizing the common flaws of these substandard seamless steel pipes.

The causes and characteristics of external folds and indentations in hot-rolled seamless steel pipes.

The root causes and effective solutions for hot-dip galvanizing leakage in seamless steel pipes, ensuring the integrity and longevity of industrial applications.

From the pipe billet to the steel pipe generally requires two heating products, namely the pre-heating and rolling tube perforated base tube is heated in a given path before; production of cold-rolled (pull) pipe requires the use of intermediate annealing to remove residual stress; For some steel special requirements, in order to improve the mechanical properties of steel pipe and improving organizational and process performance, but also its heat treatment. Steel heating tube defects uneven heating, oxidation, decarbonization, heating cracks, overheating, over-burning.
