Detail of galvanized steel pipe and stainless steel pipe
Steel pipes are ubiquitous in our daily lives, from building structures to water pipe systems, and almost all infrastructure is inseparable from them. Among the many types of steel pipes, galvanized steel pipes and stainless steel pipes have attracted much attention due to their excellent perform...Read more -
Internal anti-corrosion treatment method for large diameter spiral steel pipe
The construction of cement mortar fabric should usually be carried out after the spiral pipe has been laid, the pressure test has passed, and the covering soil has been compacted according to the planning requirements. Due to the small stiffness and thin wall of the steel pipe, the pipe must be i...Read more -
How to prevent corrosion when welding galvanized steel pipes
Anti-corrosion of galvanized steel pipe welding: after surface treatment, thermal spray zinc. If galvanizing is not possible on site, you can follow on-site anti-corrosion methods: apply epoxy zinc-rich primer, epoxy mica iron intermediate paint, and polyurethane topcoat. The thickness refers to ...Read more -
Large-diameter seamless steel pipe is a steel product formed by cold drawing, cold rolling, etc.
Large-diameter seamless steel pipes are steel products formed by cold processing such as cold drawing and cold rolling. The state in which they are delivered directly without any heat treatment is called cold drawn or cold rolled state. Compared with the hot-rolled (forged) state, steel in the co...Read more -
What are the heat treatment methods for spiral steel pipes
1. Thermomechanical treatment: High-temperature thermomechanical treatment can improve the yield ratio and elastic limit of spiral steel pipes. Improve the comprehensive mechanical properties, fatigue properties, and stress relaxation properties of spiral steel pipes. Reducing the ductile-brittle...Read more -
The main uses of thick-walled steel pipes
The biggest difference between thick-walled steel pipes and thin-walled steel pipes is the thickness of the pipe wall. Steel pipes with wall diameters greater than 0.02 are generally called thick-walled steel pipes. Thick-walled steel pipes have a very wide range of uses. Because their pipe walls...Read more -
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
