Pipe elbows are what we call pipe fittings that change direction. Pipe elbows are available in 90 degrees, 45 degrees, 180 degrees, etc., and the materials are divided into carbon steel, stainless steel, alloy steel, etc. So how do you choose 304 stainless steel pipe elbows?
How to choose 304 stainless steel pipe elbows?
1. Select according to the size of the connected pipe
Which method is more suitable for 90° equal-diameter elbows for 304 stainless steel pipes? In fact, it mainly depends on the size of the connected pipes. If the pipes used are DN15-DN60 in size, then double clamping, ring pressing, and socket welding will be more suitable. These three types are also the most commonly used ones at present, and these occasions involve home decoration water pipe installation and engineering water pipe installation.
The 90° equal-diameter elbows made of 304 stainless steel water pipes for grooves are mainly for pipes of size DN65-DN300. For example, this type of elbow is used in water supply pipe systems in projects. The water output is generally large and the water pressure can withstand more than 25 kg. If the assembly is skewed, it can be reassembled without damaging the clamp or the sealing ring, avoiding the waste of grooved pipe fittings.
2. Choose according to the construction environment
Select the appropriate material according to the construction environment. There are many kinds of stainless steel materials, and the most commonly used one is 304. This material is good in corrosion resistance and oxidation resistance, and the price is not high. The construction period can be shortened. If you choose 316 stainless steel flange elbow in coastal areas, its performance is higher than that of 304 material, but the price is also much higher.
3. Choose from powerful manufacturers
Choosing a strong manufacturer can not only guarantee product quality, but also provide after-sales service. If you encounter a problem with the stainless steel flange elbow, you can repair or replace the product on site, and the manufacturer can respond quickly. Before the products leave the factory, they will be subjected to a series of tests such as magnetic powder, ultrasonic, and X-ray to minimize the error rate of stainless steel pipe fittings.
304 stainless steel elbows knowledge
1. The production process of 304 stainless steel elbow manufacturers is basically hot pushing, stamping and medium plate welding. Hot pushing is generally used for the production of standard seamless pipes and straight seam pipe elbows. The production speed is fast and the size error of the manufactured products is small. These are the main advantages of the hot pushing process. The stamping process can manufacture thick-walled 304 stainless steel elbows, which is suitable for small batch production. Medium plate welding is generally used for the manufacture of large-diameter carbon steel elbows. It has a wide range of processing and the manufactured elbows are relatively standard.
2. In order to ensure the quality of the products, 304 stainless steel elbow manufacturers will conduct material testing on the raw materials when selecting them. If it is a large-diameter elbow, the steel plate will also be ultrasonically tested. After the large-diameter elbow is manufactured, its weld needs to be tested for flaw detection. Only those that meet the requirements can be shipped.
