Manufacturing Yield And Loss Rate Of SSAW Steel Pipe

SSAW steel pipe is formed from narrower sheets or hot-rolled coils, which is suitable for transporting large quantities of oil and gas.  And the loss rate of spiral pipe welding directly affects the cost price of spiral pipe. Therefore Union Steel attaches great importance to the loss of spiral tubes. Next, we will introduce the calculation formula of yield strength of SSAW steel pipe in detail.

Calculation Formula of Yield Strength of SSAW Steel Pipe:

b=Q/G*100

b is the finished product rate, %; Q——the weight of qualified products, in tons; G is the weight of raw materials, in tons.

The yield is in an inverse relationship with the metal consumption coefficient K.

b=(GW)/G*100=1/K

The main factor affecting material productivity is the various metal losses generated during the production process. Therefore, the method to improve material productivity is mainly to reduce various metal losses.

Because the raw materials used in each steel rolling workshop are different from the rolled products, for example, some steel rolling workshops use steel ingots as raw materials, open blanks in the middle, and roll them into raw materials; some steel rolling workshops use steel ingots as raw materials, open billets in the middle, and roll into materials; some workshops directly use steel ingots as raw materials and roll them into materials; Therefore, it is difficult to use the output calculation method to express and compare the metal harvesting situation in the production process, and it is also difficult to reflect the differences in the production technology level and management level of the workshop. There are many ways to calculate the output, such as the output of steel ingots,

SSAW Steel Pipe Loss Rate Calculation:

SSAW steel pipe manufacturing loss rate refers to the waste ratio of raw materials in the spiral steel pipe manufacturing process. According to years of statistical analysis by professional technicians, the loss rate ofspiralpipe manufacturing is between 2% and 3%.

between. In the spiral tube manufacturing process, the main components of the waste are: the front part of the spiral tube forming, the tail part, the milling of the raw material and the necessary steps in the spiral tube production process. If the spiral pipe cannot be milled according to normal standards during the production process, the mesh rate of the produced steel pipe will be very low.

How To Control The Loss Rate of SSAW Steel Pipe?

1. After the SSAW steel pipe is formed, it is necessary to cut off the first section and remove the tail to prevent the steel pipe from being uneven. This is an important process to ensure the specification and appearance of steel pipes, and waste will be generated in the process.

2. Processing of raw materials, strip steel needs to be milled before welding. During this process, waste is also produced.
