The most basic difference between stainless steel elbows and elbows is that stainless steel elbows are shorter than elbows. R=1 to 2 times is an elbow, and the bigger multiple is called an elbow. In terms of production process, cold-bent pipes can be bent by ready-made straight pipes with pipe benders, and no secondary anti-corrosion is required after one-time completion.
However, the elbow needs to be customized by the manufacturer, and anti-corrosion is required, and the ordering cycle is long. The price of the elbow is higher than that of the elbow, but the cost performance is much higher than that of the elbow. It is well known that the elbow without anticorrosion treatment is easy to damage.
Functional characteristics of stainless steel elbow
1. Good wear resistance The hardness of super-hard wear-resistant alloy is HRC≥56, which has good wear resistance and thermal stability.
2. Good heat resistance and corrosion resistance The matrix of super hard alloy material has strong heat resistance and corrosion resistance, and can show good corrosion resistance and wear resistance under high temperature or corrosive environment. Under the interaction of wet state, corrosive media and particle erosion, it is more appropriate to use super-hard wear-resistant alloys used in as-cast state; and under dry conditions where abrasive wear is the main failure mode, use a A super-hard and wear-resistant alloy material that can obtain a martensite matrix through heat treatment.
3. The impact resistance, metal bonding performance, and thermal shock resistance of stainless steel elbows. KMTBCr28 bimetal composite wear-resistant elbow, the bonding surface of the two metals is completely metallurgical, and it is safe and reliable to use. The thermal expansion coefficients of the two are the same, and there will be no swelling and shrinking and cracking. The outer wall of the elbow is made of steel pipe, and the inner lining is made of super-hard wear-resistant alloy. This product not only has the wear-resistant and corrosion-resistant properties of high-alloy products, but also has higher mechanical properties and higher impact resistance.
