Seamless pipe is made of steel block or solid pipe blank， and then made by hot rolling， cold rolling or cold dial. Seamless pipe plays an important role in Chinas steel pipe industry. Seamless pipe production processes are relatively rich， generally according to the corresponding steps of processing and production.
0 East West derusting: if the galvanized pipe surface is rusty， the manufacturer will choose East West derusting and polish it with a steel wire brush
vAlajuelitaDry processing technology: after passivation treatment， parts shall be dried with air compression or hot gas，Products Show or drying treatment or air drying can be selected.
According to the process，ConcepcionAlloy pipe GH3030How to deal with technical service contracts it is divided into arc welded pipe， resistance welded pipe (high frequency and low frequency)， gas welded pipe and furnace welded pipe.
DLa Serena Because zinc has excellent ductility and its alloy layer is firmly attached to the steel base， hot-plated parts can be formed by cold stamping， rolling， wire drawing， bending and so on without damaging the coating;
OiFrom the situation of chiseling on site the reinforcement mesh laid by the construction party is cm below the surface layer， and then the crack resistance of the reinforcement mesh can be reduced. Because of the increasing temperature which greatly exceeds the specification， the cracking of surface layer is significant.
The whole structure is composed of zinc and quaternary crystals，Products Show forming dense crystals and barrier layer on the plate， which effectively prevents the penetration of corrosion factors. From the point of view of the strong zinc corrosion resistance of the barrier layer， when the zinc sacrificial anode is at the forefront of protection， the scratches and scratches of some coatings and the insolubility of zinc oxide layer play a protective and blocking role.
Pickling: if the material cannot be removed after cleaning， pickling will be selected. Pickling of galvanized pipe is divided into chemical and electrolytic. How to prevent white rust of galvanized seamless steel pipe? It has a certain anti-corrosion effect on the pipeline.
r Frame line crack
ATransformer tube: it is used to make transformer heat dissipation tube and other heat exchangers. It is made of general carbon steel. Flattening， flaring， zigzag and hydraulic tests are required. Steel pipes are delivered in fixed length or double length， and there are certain requirements for the tortuosity of steel pipes.
PCreate brillianceThe storage of galvanized pipes should pay attention to several points. The first is the storage location. It cannot be placed in the open air， because in the open air， not only the safety of various products such as theft，Products Show but also corrosion problems will occur. Open air sites are vulnerable to various extreme weather conditions. Large amounts of rain or snow will erode the zinc coating on the surface to the greatest extent， which may lead to rust of the product. The second is the details of storage. It is not directly exposed to the sun. It shall be cooled and dried and shall not be stored with corrosive articles.
wEAre there many welded types of mesh produced? According to the welding type and overall improvement，ConcepcionAlloy pipe GH3030How to deal with technical service contracts the difference between the reinforcement mesh and the welded mesh is not particularly large. It is still due to the scattered quality of the southern city. From the perspective of development to the longitudinal and transverse interleaving devices of the reinforcement mesh， the bound or welded mesh has better application quality.
Welded thin-walled pipe: mainly used for making furniture， toys， lamps， etc. In recent years， thin-walled tubes made of stainless steel strip are widely used such as high furniture， fence and so on.
The multi-al combination of reinforcement mesh welding machine and reinforcement mesh row welding machine based on PLC basic control. At present， the full-automatic mesh welding machine has the characteristics of simple operation，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd high control precision and easy to master the process of high-speed continuous welding.
Process inspectionw The reinforcement on both sides of the inverted beam extends into the beam respectively， and the anchorage length of the reinforcement is the same as that of the reinforcement， without hook.
APerformance parameters and application scope of I-beam
Silicon; it can improve the hardness of steel， but the plasticity and toughness decrease. Electrical steel contains a certain amount of silicon， which can improve the soft magnetic properties
hAlajuelita Fabrication and installation of pipe support:
xZGalvanized steel pipe: in order to improve the corrosion resistance of steel pipe， general steel pipe (black pipe) shall be galvanized. Galvanized steel pipes are divided into hot-dip galvanizing and electro galvanizing. The hot-dip galvanizing layer is thick and the cost of electro galvanizing is low.
Various advantages of seamless pipe are widely used to manufacture structural parts and mechanical parts such as petroleum drill pipe， bicycle frame， steel scaffold for construction engineering， improve material utilization， simplify manufacturing process， save materials and processing time， and are widely manufactured with steel pipe. Only by choosing suitable seamless pipes in different fields can we save resources and improve efficiency. In the future， we will expand the research on seamless pipes and produce more seamless pipes with good performance. Please pay more attention to this website. I bring you new knowledge of seamless pipe. In recent years， seamless pipe is more widely used， the market demand of various industries is too large， there are more and more enterprises producing seamless pipe， and the product quality is more uneven.
