The oil drilling pipe is a seamless steel pipe used for thickening or external thickening at both ends of oil drilling. A series of problems such as leaking seams in the use of fake and inferior drill pipes can cause a series of serious consequences such as broken drill pipes and even buried drills in the well. As a professional drill pipe manufacturer, let me introduce how to identify fake oil drilling pipes to avoid unnecessary losses.
 

1

Fake and inferior oil drilling pipes are prone to folding. Folding is a variety of fold lines formed on the surface of an oil drill pipe, and such defects often extend throughout the longitudinal direction of the product. The folded product will crack after being bent, and the strength of the oil drilling tube will be greatly reduced.

2

The appearance of fake and inferior oil drilling pipes often has pockmarks.

3

The surface of the fake oil drilling pipe is prone to scarring.

4

The surface of the fake inferior material is prone to cracks.

5

The fake oil drilling pipe is easy to scratch.

6

The fake oil drill pipe has no metallic luster and is light red or similar to pig iron.

 

7

The cross-fabricity of the fake and inferior oil drilling pipe is thin and low, and there is often a phenomenon of dissatisfaction.

8

The cross section of the fake oil drilling pipe is elliptical.

9

The composition of the high-quality oil drilling pipe is uniform, the tonnage of the cold-shearing machine is high, the end face of the cutting head is smooth and tidy, and the fake inferior material is often poor in material, and the end face of the cutting head often has a phenomenon of falling meat, that is, unevenness and no metallic luster. And because the fake inferior products manufacturers have fewer heads, big ears will appear at the head and tail.

10

The material of the fake and inferior oil drilling pipe contains many impurities, the density of the steel is small, and the size is too bad, so in the absence of the vernier caliper, it can be weighed and checked. In general, the phase comparison effect will be better.

11

The inner diameter of the counterfeit oil drilling pipe fluctuates greatly

12

The trademarks and printing of high-quality materials are relatively standardized.

 

13

The oil drilling pipe has a large thread with a diameter of 16 or more, and the distance between the two trademarks is above IM.

14

The longitudinal reinforcement of the fake oil drilling pipe is often wavy

15

The fake and inferior oil drilling pipe manufacturers have loose packaging because they do not have driving. The sides are oval.

The so-called workers want to be good at things must first sharpen their tools, only choose high-quality oil drilling tubes to avoid unnecessary losses.
