SPHERICAL PLAIN BEARING
Produced from:HGF
Introduction：
Spherical plain bearing is a spherical sliding bearing whose sliding contact surface is an inner spherical surface and an outer spherical surface. It can be rotated and oscillated at any angle during movement. It is made by surface phosphating, blasting, inlaying, spraying and other processing methods.
Spherical plain bearings have the characteristics of large load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning and good lubrication.

Description
Galvanized pipes have a wide range of uses. In addition to oil and other low-pressure fluid pipelines, it is also used as oil well pipes in the petroleum industry, especially in offshore oil fields, oil heaters in chemical coking equipment, coal distillation, and oil washing converter pipes, bridges, etc. Pipe pile, mining tunnel support frame with pipe, etc. Developed countries in the world started to develop new pipes and continuously banned galvanized pipes.
This is a hot-rolled pure structural steel. With good plasticity, toughness, and weldability, it has a loweryield strength of 185 - 235MPa. This material can be formed into many products such as I beams,channels, plates, angle bars etc.its excellent weldability makes it to be widely used in bridges,transmission towers etc. It is equivalent to Fe360B. Any steel with similar chemical and mechanical properties can be designated as S235JR material.
Product introduction：
Galvanized steel pipe is divided into cold galvanized steel pipe, hot galvanized steel pipe, cold galvanized steel pipe has been banned, the latter is also advocated by the state can be used temporarily.
Application：
Hot-dip galvanized steel pipe is widely used in construction, machinery, coal mine, chemical industry, electric power, railway vehicles, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, mining machinery, greenhouse construction and other manufacturing industries.Galvanized steel pipe Welded steel pipe with hot dip plating or electrogalvanized coating. Galvanized steel pipe can increase the corrosion resistance, prolong the service life. Galvanized pipe has a wide range of uses, in addition to the pipeline pipe for water, gas, oil and other general low pressure fluid, but also used in the petroleum industry, especially the oil well pipe, oil pipeline, chemical coking equipment of the oil heater, condensate cooler, coal distillation and washing oil exchanger with the pipe, and trestle pipe pile, mine tunnel support frame with pipe.
