【History】A brief history of China's pipeline development

Pipelines are connected by Pipelines, Pipeline couplings and valves to transport gas, liquid or fluid devices with solid particles. In fact, this kind of device has been used in ancient China thousands of years ago. The evolution of human water supply Pipelinelines for thousands of years is also the evolutionary history of human civilization.

How much do you know about the production of stainless steel pipe fittings

Stainless steel pipe fittings are very commonly used in construction. According to the connection method of stainless steel pipes, they are divided into four types: socket pipe, threaded pipe, flange pipe and welded pipe. Stainless steel pipe is also a kind of pipe, made of stainless steel material, so it is called stainless steel pipe. Stainless steel is a very good material, and stainless steel pipes also have outstanding advantages among various pipe fittings. Stainless steel pipes include stainless steel elbows, stainless steel tees, stainless steel crosses, stainless steel special-shaped pipes, stainless steel caps, etc. According to the fastening method, it is divided into sleeve type stainless steel pipe, threaded stainless steel pipe, flange stainless steel pipe and welding.

Little knowledge of carbon steel elbow!

Carbon steel elbow is a kind of elbow conveying medium, high-density polyethylene outer tube and polyurethane rigid foam carbon steel layer filled between the elbow and outer tube tightly combined, it is a kind of high-density polyethylene Protecting pipe polyurethane foam plastic prefabricated direct buried carbon steel elbow, only need to put the rust and anti-corrosion elbow in the polyethylene sleeve, inject polyurethane foam in the middle to fully fill the gap between the elbow and the polyethylene sleeve In the later stage, the elbow, casing, and carbon steel layer form a solid whole to achieve the effect of anti-corrosion carbon steel, and the carbon steel elbow is formed.

Explain the corrosion detection method of butt welding elbow in detail

Butt welded elbows can be corroded in inaccurate use. After butt welded elbows are corroded, the pipe wall of butt welded elbows usually becomes thinner, and one-sided pits and pits appear. Detection method of butt welding elbow after erosion: The basic principle of flux leakage detection is based on the basic characteristic of high permeability of ferromagnetic material.

Storage method of stainless steel tee

Stainless steel tee is a pipe fitting with excellent performance and corrosion resistance. There is a big difference between tee and elbow and pipe, but in pipeline construction, tee has also been widely used. Although stainless steel tees have good corrosion resistance, they still need attention in actual storage. Otherwise it will have a certain impact on the quality of the tee.

High pressure elbow use matters needing attention

welding rod use should be kept dry, titanium calcium type should be after drying at 150 deg.c for 1 hours, low hydrogen type should by 200-250 ℃ dry 1 hours (not repeated drying, or medicine skin easy cracking and spalling), prevent the covering of viscous oil and other dirt, so as not to cause increased carbon content and the influence of welding seam the welding quality.
