Precautions for galvanized pipe storage
3 The zinc coating is thick， the crystallization is detailed， uniform and non porous and the corrosion resistance is excellent;
wAustinThe wear resistance， fracture toughness， impact toughness and bending strength under different process conditions were compared， and then the heat treatment process of GCrMo was determined. Development and application of ZYS- bearing damping and antirust oil. Bearing is a new type of multial damping and antirust oil. It takes refined mineral oil as the base oil and is equipped with various additives such as antirust and antifriction. Through comparison test，Products Show matching test with lubricating grease and user test，San Jose10CrMoAl alloy pipeThe trend of price adjustment differentiation remains unchanged it is proved that ZYS- bearing damping and antirust oil has outstanding damping effect and good antirust lubrication performance.
The monthly summary of the real estate industry shows that there is a significant positive correlation between the market sales and the long-term trend of the apparent consumption of galvanized pipe， but there will also be a backwardness of the market in a special stage， and after the backwardness of the market in stages， there will be a rapid decline in the moving average of the apparent consumption of galvanized pipe， welded steel pipe and so on.
RYemen The zinc layer obtained by electroplating is relatively pure which corrodes slowly in acid， and can effectively maintain the steel matrix;
OrFirst， the two hole beam end space on the pier top shall be used to set the cast-in-situ transverse cantilever cantilever beam， on which the prefabricated micro bending plate shall be installed. The second is to erect prefabricated sidewalk beams in the cantilever part of the cantilever beam. The sidewalk beams of bridge openings on both sides are longer than the main beam， one end is supported on the cantilever beam of side pier，Products Show which is to avoid widening the abutment.
Installing the pipe structure means the complexity of some elements.
Cutting machine， electric welding machine， polishing machine electric hammer， etc
oUsing alloy pipe to produce ring parts can improve the utilization rate of raw materials， simplify the production and manufacturing process， and save raw materials and production and processing construction time， such as roller bearing ring throwing Nowadays， seamless steel pipe has been widely used to produce hydraulic jack sleeve.
R As long as the pipe material is high-strength alloy steel， including alloy steel pipes with temperature resistance， pressure resistance，Products Show wear resistance and low temperature resistance， the welding process shall be focused on preventing the tendency of martensite structure and cracks due to welding high-temperature operation. The general process requirements are that the welding rod shall be selected and baked as required and sent to the welder for use. The oil and water shall be removed before welding on both sides of the weld Rust and sundries shall be removed and cleaned. The welding line energy shall be as small as possible to minimize the swing during the welding process. The arrangement of the last weld shall have annealing effect on the heat affected zone as far as possible. Slow cooling after welding，San Jose10CrMoAl alloy pipeThe trend of price adjustment differentiation remains unchanged cover with asbestos cloth， etc.
NWhere can I find it?A major defect is its instability to the corrosion process， which can not resist all factors. Producers need a solution that can solve the corrosion problem. The decision has been found. They become a galvanized steel pipe.
tAGalvanized pipe is a kind of light thin-walled steel pipe with hollow square section， which is made of Q hot-rolled or cold-rolled strip or coil as the base material， cold bending and high-frequency welding. In addition to wall thickness thickening， the corner size and edge flatness of hot rolled extra thick wall galvanized pipe reach or even exceed the level of resistance welding cold formed galvanized pipe.
The zinc layer obtained by electroplating is relatively pure， which corrodes slowly in acid， alkali and other fog，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd and can effectively maintain the steel matrix;
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
originalz The weight of seamless pipe is light， and its weight is only one fifth of that of anti steel.
Q→ wide flange and large lateral stiffness. Strong bending resistance.
Cleaning: first， clean the grease， dust and other substances attached to the surface of the galvanized pipe after cleaning.
oAustin Spiral welded steel pipe (sy- for pile is made of hot-rolled steel strip coil as pipe blank， often warm spiral forming， double-sided submerged arc welding or high-frequency welding. It is used for foundation pile of civil building structure， wharf， bridge， etc.
pHWelded 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， decoration， fence and so on.
