aprince Albert c.quality inspection is carried out for alloy pipes， so that the whole process of steel pipe processing is under reasonable inspection and supervision， and the product quality is reasonably guaranteed.
EAfghanistanThe whole structure is composed of zinc and quaternary crystals， 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， the scratches and scratches of some coatings and the insolubility of zinc oxide layer play a protective and blocking role.
CpThe two ends of the steel produced by the seamless pipe manufacturer shall be cut into right angles， and the burrs on the surface shall be removed， which is the raw material used by the seamless pipe manufacturer. The embryo prototube embryo needs to be cut by a cutting machine to form an embryo material with a length of about one meter，Products Show which is sent to the furnace for heating through the conveyor belt. The billet is sent to the furnace. After internal heating， the temperature is about degrees，Jolett45# precision seamless pipeProspects and industry situation and the fuel used is often ethyne. Temperature control in the furnace is a very key factor.
The use of welded steel mesh can make the project construction convenient. As long as the welded reinforcement mesh is laid as required， the concrete can be irrigated， placing and binding of reinforcement one by one.
Galvanized pipe: the hot-dip galvanized pipe base plate and molten electroplating solution are combined physically and chemically to form a dense corrosion-resistant structure of zinc iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe substrate. Therefore， it has strong corrosion resistance.
gThe 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， it is proved that ZYS- bearing damping and antirust oil has outstanding damping effect and good antirust lubrication performance.
ZAccording to the historical records of the recent four years，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd the zinc price in the first quarter was generally higher than that in the whole year， and generally entered a wave of upward trend in the first quarter. However， zinc prices continued to decline in the first quarter of ， and showed a trend of accelerating the decline day by day. There are two key reasons for the beginning of this year. First the vicious change of the real estate industry has led to a rapid decline in the growth rate of Chinas consumption of galvanized pipe and seamless steel pipe， and even a contraction month on month; Secondly， the blind expansion of galvanized pipe factory confused the sense of rhythm of supply and demand balance.
IQuality risk Seismic and cracking performance the longitudinal and transverse bars of the welded reinforcement mesh form a network structure， so it has good bonding and anchorage with the concrete， and the load can be evenly distributed， which obviously shows the seismic cracking performance of the reinforced concrete structure. According to the actual test， the welded reinforcement mesh laid on the road can reduce the occurrence of cracks than the manual binding mesh. It greatly reduces the unnecessary cost generated manually in the construction and shortens the construction period. The use of reinforcement mesh is simple and convenient and the reinforcement mesh is convenient for transportation.
uKThe production methods of seamless pipe are roughly divided into cross rolling method and extrusion method. The cross rolling method is to drill the tube with a cross roll， and then extend it to the rolling mill. This method has fast production speed， but has high requirements for the workability of the blank. It is mainly suitable for the production of carbon steel and low alloy steel pipes. The extrusion law is to pierce the blank or ingot with a punch， and then squeeze it with a steel pipe with an extruder. The efficiency of this method is lower than that of cross rolling method. It is suitable for producing high-strength alloy steel pipe. The billet or ingot must be heated before cross rolling method and extrusion method. The produced steel pipe is called thermal correlation. Steel pipes produced by hot working can sometimes be cold worked as needed. There are two methods of cold working. One is cold drawing. In other words， pull the pipe to the pipe and tilt it to make the steel pipe gradually thinner and longer. Another method is cold rolling. The method of applying the hot smoke invented by brother to cold processing. The cold working of seamless pipe can improve the dimensional accuracy and finishing of steel pipe， and improve the mechanical properties of materials.
Next， lets introduce the operation steps of roll adjustment during roll change. First of all， we must replace the specification and model of the welded pipe manufacturer. Generally， replace the complete set of rolls. The adjustment process of the rolls is as follows: first， draw an axis from the channel of the generator set to the import and export with stainless steel wire for adjustment， so that the holes of each frame plate are on the same axis， and the bottom line of forming ethics meets the technical standards.
External steel bonding reinforcement method is a more traditional reinforcement method. The utility model uses an adhesive to paste the steel plate or reinforcement mesh on the cracked part of the wall to achieve the purpose of reinforcement. The commonly used adhesive is usually epoxy resin. This method is simple and fast in construction and has little impact on production and life. Basically， the bearing capacity of the wall can be greatly improved without changing the shape and internal use space of the components. It is mainly applicable to the reinforcement of walls that do not allow to increase the section size of original components， especially micro seal and polymer modified seal， which greatly increases the strength and integrity of the pavement.
VDry processing technology: after passivation treatment， parts shall be dried with air compression or hot gas， or drying treatment or air drying can be selected.
Installing the pipe structure means the complexity of some elements.
oprince Albert The preparations for the construction of high-speed reinforcement mesh include the preparation and inspection of raw materials， the inspection and acceptance of the lower layer of the pavement， and the preparation of construction equipment and engineering machinery.
lK The rapid popularization and application of cold drawn ribbed bars and hot rolled grade III bars in China provides a good material basis for the development of welded mesh. The formal implementation of welding net product standards and application procedures has played a positive role in product quality and accelerating popularization and application.
There is a great demand for welded steel mesh in Chinas market.
