How To Prevent Long Spots Of Stainless Steel Pipe Fittings

- May 20, 2019-

The stainless steel pipe fittings belong to a small part of the pipe fittings. Because they are made of stainless steel, they are called stainless steel pipe fittings. There are many members in them, including common elbows, tees, crosses, Stainless steel reducers, etc., are attributed to pipe rust steel pipe fittings. According to the connection method, we can divide the stainless steel pipe fittings into four categories: stainless steel pipe fittings, threaded stainless steel pipe fittings, welded stainless steel pipe fittings and flanged stainless steel pipe fittings. The stainless steel materials that are primarily used to make stainless steel pipe fittings are 304, 304L, 316, and 316L.


Stainless steel pipe processing

Then, when using an ultrasonic cleaner to clean stainless steel pipe fittings, why does his appearance appear many gray-black mottled? In fact, this is an oxidation reaction, a strong oxidizing acid, and the inside of the chloride ions will pitting the appearance of the stainless steel pipe fittings, forming a gray-black mottle seen by the naked eye. However, it is still necessary to analyze the specific situation. It depends on what kind of state your stainless steel pipe fittings are in before cleaning. What is the reason for this.


Stainless steel pipe fittings are made because the steel material is coated with a layer of rust-preventing material, and rust is clarified that the coating has been damaged, so it will rust. The cause of the damage is mostly due to corrosion.


Various processing methods for stainless steel pipe fittings

High-quality stainless steel pipe fittings must be satisfied with all aspects of precision requirements. Only in this way will the user be satisfied with the application, then what is the accuracy requirement of this product demand? The first is the requirement for satisfactory accuracy on the dimensional standard. Because there are many standards for this product, different standards will be used under different operating environments, so it is required to meet the accuracy requirements of the product standard but it is required in the profession. Among them, some manufacturers have no precision in standards because they do not have professional standards.


In fact, there are many classifications of stainless steel pipe fittings. According to the different classifications, the processing methods applied to them are different. In fact, it can also be a way to distinguish different stainless steel pipe fittings. Various stainless steel pipe fittings are also used. Can be very satisfied with the functions required for stainless steel pipe fittings in different working environments of different occupations.


1. The manufacturing process of stainless steel pipe fittings can be divided into the following basic categories: hot rolling (kneading), cold rolling (pull), and hot expansion of steel pipes.

2, welded stainless steel pipe fittings can be divided into: straight seam welded steel pipe, submerged arc welded steel pipe, coiled butt welded steel pipe, welded pipe hot expanded steel pipe according to the production process.

3. According to the shape of stainless steel pipe fittings, it can be divided into square tube, rectangular tube, octagonal, hexagonal, D-shaped, pentagonal and other special-shaped steel pipes. Complex section steel pipe, double concave steel pipe, five-petal plum-shaped steel pipe, conical steel pipe, corrugated steel pipe, melon-shaped steel pipe, double convex steel pipe, etc.

4, according to the use of classification - pipeline steel pipe, thermal equipment steel pipe, machinery industry steel pipe, petroleum, geological drilling steel pipe, container steel pipe, chemical industry steel pipe, special use steel pipe, and others.
