How to prevent spiral steel pipe from being damaged during transportation
1.Fixed-length spiral steel pipes can be unbundled. 2.If the two ends of the spiral steel pipe are threaded, they should be protected by thread protectors. Apply lubricant or rust inhibitor on the thread. The two ends of the spiral steel pipe are broken, and the two ends can be equipped with nozz...Read more -
What is the function of the three links and four links to steel pipe fittings
The three links are steel pipe fittings and pipe connectors. Also called three-way pipe fittings or three-way pipe fittings, three-way joints, used in the branch of the main pipeline. Tees are divided into equal diameters and reducing diameters. The connecting ends of equal diameter tees are all ...Read more -
Antibacterial stainless steel
In the production of kitchen equipment, medical equipment, bathroom supplies, and cleaning and decoration, people have been looking forward to the emergence of new metal materials that can be both antibacterial and styling. A new material with both structural and functional characteristics-antiba...Read more -
Comparison of technical characteristics of spiral welded pipe and longitudinal welded pipe
Comparison of technical characteristics of spiral welded pipe and straight-seam welded pipe: ·Metallurgical properties of materials LSAW pipes are produced from steel plates, while spiral welded pipes are produced from hot-rolled coils. The rolling process of the hot strip steel mill has a series...Read more -
Testing method of coated steel pipe
A. Visual inspection Visually inspects the appearance quality of the coated steel pipe. B. Thickness measurement Take two cross-sections of different lengths from the two ends of the coated steel pipe, and measure the coating thickness at any four points on the circumference at right angles with ...Read more -
Longitudinal welded pipe anti-rust maintenance and inspection methods
The longitudinal welded pipe has a simple production process, high production efficiency, low cost, and rapid development. The strength of spiral welded pipes is generally higher than that of straight seam welded pipes. A narrower blank can be used to produce welded pipes with larger pipe diamete...Read more -
What is the difference between cold-drawn steel pipe and hot-rolled steel pipe
(1) The difference between hot working and cold working: hot rolling is hot working, and cold drawing is cold working. The main difference: is that hot rolling is rolling above the recrystallization temperature, cold rolling is rolling below the recrystallization temperature, and cold rolling is ...Read more -
Anti-corrosion practices for buried steel pipes
Pipe rust removal → Apply primer → Top coat → Second coat of top coat → Wrap glass silk cloth → Top coat → Top coat; Inner wall construction process: pipe rust removal → primer application → top coat → second top coat → third top coat 1. Pipe rust removal Before applying primer, the surface of th...Read more -
How to control the quality of high frequency welding steel pipe
The main points of high-frequency welding quality control In the process of high-frequency welding of steel pipes, the control of the welding process and process parameters, the placement of the induction coil and the impedance device, etc. have a great influence on the welding quality of the ste...Read more -
What properties should the anti-corrosion layer of steel pipelines have
The anti-corrosion layer of steel pipelines should have the following properties: (1) Effective electrical insulation. (2) It has good moisture-proof and waterproof properties. (3) It has muscular mechanical strength. (4) The anti-corrosion layer has good adhesion to the steel surface. (5) The ma...Read more -
What measures can be taken to reduce the resistance of steel pipe fittings
The resistance of the fluid is responsible for energy loss (i.e. drag loss). One is the resistance loss along the way caused by the viscosity and inertia of the fluid; the other is caused by the sudden expansion or contraction of the pipeline-interface, etc. The blocking and disturbance effects o...Read more -
What are the common categories of stainless steel pipes on the market
1. Production method: Stainless steel welded pipes are divided into two categories: seamless pipes and welded pipes according to the production method. Seamless steel pipes can be divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, and extruded pipes. Cold-drawn, cold-rolled It is...Read more
