The steel pipe is not straight? I will help you solve it. The straightness of seamless steel pipe does not meet the standard and affects processing. Recently, many customers have asked about the straightness of seamless steel pipes. After talking, I found that these customers need to process them later, and the steel pipe is too bent, which will cause great trouble. The delivery status, size, steel grade, etc. of the steel pipe are all factors that affect the straightness of seamless steel pipes.
Because the steel pipe is not straight, have you also encountered the following processing problems?
(1) Cutting yield: The bend of seamless steel pipe will cause great trouble to the customer during the cutting process. The steel pipe will jump when it bends, making it difficult to cut. The cutting error is large, which directly leads to a decrease in the product yield.
(2) Product accuracy: Product accuracy is a requirement of the product itself. For example, seamless steel pipes are used in pairs, one steel pipe is inserted into another steel pipe. If the steel pipe is bent, it will not fit in, resulting in the scrapping of the entire batch of pipes.
Real case analysis: The impact of straightness on product accuracy. We have such a case. Previously, there was a customer who needed motor piping. The outer diameter was 35mm, the inner hole was 31mm, and it was delivered in a cold state. The finished product length needed to be 4.4 meters, and the straightness requirement was 1mm/m. The inside and outside were used together, and the 28mm pipe was stuffed inside. If the outer pipe was bent and the straightness was poor, the inner pipe could not be stuffed in completely. This customer previously chose a supplier with a cheap quotation because of the price problem, but because the supplier did not have professional equipment, the straightness could not be achieved, and the delivery time was always delayed. After changing suppliers many times without success, he finally found professional equipment for steel pipes to solve the problem for the customer, so price is not the only selection condition.
How does seamless steel pipe achieve straightness requirements higher than the national standard?
Seamless steel pipes mainly use professional straightening equipment and “root-to-root quality inspection” inspection procedures to ensure straightness accuracy. We not only have 7-roll straightening machines and high-precision straightening machines for special-shaped steel pipes but also added 11-roll straightening machines to meet customers’ high straightness requirements. Professional equipment and 31 years of rich experience to meet customers’ different straightness requirements.
