Stainless steel seamless elbows have good corrosion resistance due to the performance advantages of the material itself, and are not prone to corrosion, pitting, rust or wear during use. Manufacturing process of stainless steel seamless elbows: Using round tube billets as raw materials, they are cut into 1-meter-long billets by a cutting machine, and sent to the furnace for heating [...]

The processing forms of stainless steel seamless elbows are mainly the following 5 categories: 1. Forging: Use a forging machine to punch out the end or part of the pipe to reduce the outer diameter. 2. Rolling: Rolling is suitable for the inner round edge of thick-walled pipes. Generally, a mandrel is not used. A core is placed in the [...]

The outer arc calculation of the stainless steel seamless elbow is the bending radius plus the radius of the pipe, which equals the outer arc radius. The inner arc calculation of the stainless steel seamless elbow is the inner arc radius of the general 90° elbow, which is equivalent to the diameter of the pipe.

The following aspects need to be considered when choosing a suitable stainless steel seamless elbow: 1. Material selection. Suitable materials should take into account the pressure, temperature, medium and other environmental factors. Generally, seamless elbows are selected for occasions requiring high strength, high precision and high corrosion resistance, while seamed elbows are considered for ordinary low pressure, low temperature and [...]

If the stainless steel seamless elbow has cracks during use, it is necessary to consider many reasons such as the raw materials, processing technology and equipment used. 1. Raw material issues If the quality of the stainless steel seamless elbow material selected is poor, the tube blank will be prone to internal and external warping, scarring and cracks. 2. Temperature [...]

Dip quenching is a processing technology for stainless steel seamless elbows. There are three common methods: 1. Dip quenching and axially spray water inside the steel pipe This method has requirements for the length of the steel pipe. Exceeding the corresponding length will lead to poor quenching performance. 2. Dip quenching and add axial water injection inside and outside the [...]
