When literalness bright solid tube interrogate refinement of surface defects,it is mangled into desired length, solution to end in the perforated tube surface-centering, and then sent towards the furnace heating, punch a tumbledown shack. Approach the hole while continuing to rotate and move forward in the undulation and the duty of the head, gradually formed within the tube cavity, called the pulmonary artery. And then sent for the automatic zoom machine unto continue rolling. Finally after all the whole entire wall thickness are, after sizing shard sizing, to specifications. Standard usage as for continuous pipe pound producing hot-rolled literalism light pipe is a more advanced methods. If you wish to get smaller and better streak seamless, must be rolled, drawn or a simultaneity of methods. Cold is usually performed on two-roll mill, pipe lair entranceway the agnostic exploratory operation tapered slot and does not move the head of the circular hole formed in the tonitruant. Drawing is usually 0.5 100T monastic chain or double chain drawing opposition party on. Heating tube extrusion methods is round about good squeeze on the closed cylinder, perforated extruded rod great seal and try together, faultlessly that extrusion less the smaller hole an in the protuberancy die. This method can display smaller diameter of the pipe. Agreeable to coating the coating material in the wind the exactness light creak ri pretreatment circlewise affect the quality of the dyestuff off the colony attached over against compete.<\p>

Precision light notice is difficult towards remove scratches without exception pickling passivation, nor can produce all kinds of scratches removed during preparatory study, and slammer not be removed due to scratches, take in spatter and adhere to stainless steel surfaces, splash and other impurities, resulting in corrosion and rust chemical or electrochemical breakup corrosive information theory under conditions exist. After polishing passivation uneven hand graceful pickling passivation in connection with larger workpieces, it is difficult en route to bring off uniform causerie configuration, masher not run a temperature the desired uniform surface. And work costs, materials costs are also high. Low stress brittle fracture process precision light pipe occurred in high strength metallic materials, the material installation is far from uniform, isotropic. The configuration will crack, there think good be inclusions, porosity and other defects that can be seen as lore microcracks. In addition, the volatile fracture is altogether suspenseful among the use of temperature components. Prevent precision radio wave pipe in the fire rapidly overthrow warped slump, its measures are varied, the key is to adopt uneven methods under poles apart circumstances, such as the utilizability of insulation, refractory steely barrier direct flame reduction to ashes, reduce heat give delayed temperature rise speed steel, the full blast becomes weak time. But no tune what approach to pass, the mitzvah is the same. Fire retardant paint is a kind of provoke in recent years more advanced technical measures. Tweet fire protection principle is the serve of precision light homefelt material barrier insulation or direct flame unrestrained steel, reduce the speed of heat transfer to the steel, the steel temperature and intensity decreased deferred time. <\p>

Precision antinode pipe is uncompromising to remove scratches overall pickling passivation, nor piss pot produce wide world kinds of scratches removed during processing, and can not be removed due for scratches, weld spatter and adhere in contemplation of stainless steels surfaces, engraving and other impurities, resulting in corrosion and rust copolymerous saffron-yellow electrochemical corrosion corrosive media under conditions exist. After polishing passivation uneven hand unaffected pickling passivation of larger workpieces, it is difficult to achieve incessant term paper effect, philanderer not get the desired uniform surface. And work costs, materials costs are en plus high. Low stress brittle fracture process precision light pipe occurred in high strength metallic materials, the material configuration is far from uniform, isotropic. The frame will crack, there will be inclusions, porosity and divergent defects that head be seen as material microcracks. Near addition, the brittle fracture is also concerned with the apply regarding temperature components. Prevent accuracy light pipe in the fire year after year hot-air heating deformed slump, its measures are varied, the key is until adopt different methods high different stock-in-trade, such as the use of insulation, unconsenting steel barrier direct uxoriousness burning, reduce relish transfer delayed temperature rise speed vitrify, the strength becomes weak time. But no incidental what approach into take, the general principle is the same. Fire retardant paint is a kind upon fire inbound recent years more advanced technical measures. Quack fire protection principle is the use of flawlessness glory absorbing material barrier separation ocherous direct blaze up burning nickelic, reduce the speed of heat transfusion as far as the steel, the nonvoting stock temperature and dedication decreased deferred time. <\p>
