Identification method of fake API 5L PSL2 X42 seamless steel pipe



As we all know there are lots of steel suppliers in the world, but not all of them produce the high quality API 5L PSL2 X42 seamless steel pipe. Katalor has the rich experience in API 5L PSL2 X42 seamless steel pipe. And next we will tell you how to find the fake API 5L PSL2 X42 seamless steel pipe.


1. Easy to present the fold. The occurrence of folding is a variety of fold lines formed by the appearance of API 5L PSL2 X42 seamless steel pipe, which usually runs through the longitudinal direction of the pipe. Folding occurs because the counterfeit manufacturers seek high efficiency, the amount of pressing is too large, and the ear is generated. When the next rolling occurs, the folding occurs, and the folded API 5L PSL2 X42 seamless steel pipe is cracked after being bent, and the strength of API 5L PSL2 X42 seamless steel pipe is greatly reduced.

2. The appearance often has the appearance of pockmarks. Counterfeit seamless steel pipe manufacturers should seek profit, often exhibiting over-rolling of rolling mills, and the wear of the groove is serious, resulting in irregularities in the irregularity of the API 5L PSL2 X42 seamless steel pipe.

3. Susceptible to crusting. Two reasons, one is that the seamless raw material of the  API 5L PSL2 X42 seamless steel pipe is uneven, and there are many impurities; the second is that the guide equipment of the fake and inferior manufacturers is simple, and these impurities are prone to scarring after rolling.

4. Prone to cracks. Since the raw material is adobe and the adobe has many pores, the adobe undergoes thermal stress during the cooling process, and cracks occur, and cracks are generated after rolling.

5. Easy to scratch. The equipment of the fake and inferior manufacturers is rudimentary, and it is prone to burr scratching the appearance of the API 5L PSL2 X42 seamless steel pipe. The strength of the API 5L PSL2 X42 seamless steel pipe is lowered after the deep scratch.

6. No metallic luster, light red or similar to pig iron. There are two reasons for this: First, its raw material is adobe; second, the temperature of the fake raw materials is not standardized, and the steel temperature is measured by visual inspection.

7. The thin and low API 5L PSL2 X42 seamless steel pipe is often showing a dissatisfied appearance. The reason is that in order to achieve a large negative tolerance, the amount of reduction of the first few passes of the product is too large, the iron type is too small, and the hole type is not full.


Katalor as a professional API 5L PSL2 X42 seamless steel pipe supplier in China, we only produce the high-quality API 5L PSL2 X42 seamless steel pipe for customers. So if you have any need in API 5L PSL2 X42 seamless steel pipe, you can contact us. We will reply you at first time.

ASTM A517 steel belongs to the boiler steel plate

-
ASTM A517 steel (also called ASME SA517 standard) is a kind of high-strength quenched and tempered alloy steel plates intended for use in fusion welded boilers and other pressure vessels. The steel shall be killed and shall conform to the fine austenitic grain size requirement. Under this specification, the plate thickness determines the grade selection and the mechanical properties.   A517 grade A steel pates 2.5" in thickness and under, will have minimum Yield Strength of 100 ksi.  A517 grade b steel plates over 2.5" in thickness will have a minimum Yield strength of 90 ksi.  Typical applications include unfired vessels and tanks. ASTM A517 Grade A plates are Pressure Vessel Plate and supplied in the as-rolled condition. The ASTM A517 Gr. A plate may be ordered normalized or stress relieved, or both. ASTM A517 Grade H are Pressure Vessel Plate and supplied in the as-rolled condition. The ASTM A517 Gr. H Plate may be ordered normalized or stress relieved, or both. AS

Katalor has more useful S235JR steel plate information S235JR steel plate  is a kind steel grade and it is mainly used for steel structural buildings, frames and other steel body under the standard of EN 10025-2.  S235JR steel plate  is for low temperature impacting test under zero centigree. Katalor steel Industrial specialized in S235JR steel plate  in china many decades years. The composition characteristics of S235JR steel plate  are low carbon, less than 0.20%, low alloy and total alloy element less than 3%. Low carbon content in S235JR steel plate  steel is to meet the technical requirements of plasticity, toughness, weldability and cold deformation of S235JR steel plate  used for engineering structural parts. The S235JR steel plate  has Mn as the main additive and conforms to the resource characteristics of our country. Mn not only has a significant strengthening effect on ferrite , but also reduces the cold and brittle temperature of the S235JR steel plate , and

How to storage the EN 10025-2 S235J0 channel steel correctly Generally, the storage of Katalor EN 10025-2 S235J0 channel steel will be placed in the storehouse. Although this environment is favorable to its storage, it should be noted that EN 10025-2 S235J0 channel steel quality will also be affected by its placing method. Therefore, when placing EN 10025-2 S235J0 channel steel, there are several things to pay attention to: First, the same type of EN 10025-2 S235J0 channel steel is stacked separately according to the order of storage, so as to facilitate the implementation of the principle of advanced first issue. Moreover, the principle of stacking requires that under the conditions of stable palletizing and ensuring safety, the stacking should be carried out according to varieties and specifications. Different materials of EN 10025-2 S235J0 channel steel should be palletized separately to prevent confusion and mutual corrosion. Second, the stacking he
