Hot-rolled seamless steel tubes are divided into general steel tubes, low- and medium-pressure boiler steel tubes, high-pressure boiler tubes, alloy steel tubes, stainless steel tubes, petroleum cracking tubes, geological steel tubes, and other steel tubes.
Advantages of hot-rolled seamless steel tube: It can destroy the cast structure of steel ingot, refine the grain of steel, and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the steel is no longer isotropic; to a certain extent, the bubbles, cracks and looseness formed during pouring can also be welded under high temperature and pressure.

The Coal Gasifier Plant produced by our company are divided into single-stage Coal Gasifier and double-stages coal gasifier . According to the diameter of the furnace, the single-stage gasifier is divided into different types. Our company can provide the range of furnace diameter size from 0.8m to 3.4m . Single-stage coal gasifier has the same good operability as electric furnace and oil stove. Single-stage gasifier is a kind of equipment with low cost and high profit.
