Question 1: What is the quota of openings in the steel pipe set quota subheading Look at the quota description: the scene in the main tube on the eye to take over the tee and wrestle with the system reducer, according to the actual number of implementation of the project in this chapter, but shall not be implemented fittings to produce the quota.
Problem two: what is the quota of steel casing electrical or drainage
Problem three: what is the quota of two-meter diameter steel pipe set to find the steel coil
Problem four: what is the quota of stainless steel pipe welding set 1, set the quota of galvanized steel pipe, the main material according to the stainless steel pipe set.
2, the quota refers to a certain technical and organizational conditions, the production of qualified units of products consumed by manpower, material resources, financial resources and time and other quantitative standards. That is, in a reasonable labor organization and reasonable use of materials and machinery under the conditions, pre-specify the completion of the unit of qualified products consumed by the number of resources of the standard, which reflects a certain period of high and low levels of social productivity. For each construction project, the amount of labor used is measured, including basic labor and other labor. Then add the materials for this project, including basic materials and other materials. For the unit price of labor, is the local according to the labor value of different types of labor at that time, the value of the material is based on the market price of the previous period to develop a budget price.
3, stainless steel pipe is a hollow long round steel, mainly widely used in petroleum, chemical, medical, food, light industry, machinery and instrumentation and other industrial transportation pipeline, as well as mechanical structural components. In addition, in the bending, torsion strength is the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. Also commonly used for the production of various conventional weapons, gun barrels, shells, etc..
Question 5: What is the quota for seamless steel pipe set LiaoCheng Tianshuo Steel Pipe Co. 40cr seamless steel pipe, large caliber seamless steel pipe, to ensure the lowest price of seamless steel pipe, first-class quality, to provide the theoretical weight table of seamless steel pipe. Can be customized according to customer requirements fixed size seamless steel pipe non-standard seamless steel pipe (in addition to the specifications other than the national standard), seamless steel pipe for structural use, seamless steel pipe for fluid use, seamless steel pipe for hydraulic use, seamless steel pipe for electric power use, seamless steel pipe for petroleum transportation, seamless steel pipe for chemical fertilizer equipment, seamless steel pipe for coal mine use, seamless steel pipe for stainless steel, seamless steel pipe for chemical industry use, seamless steel pipe for textile machinery use, automobile; seamless steel pipe for water use, precision seamless steel pipe, bright seamless steel pipe, seamless steel pipe for water use, precision seamless steel pipe, seamless steel pipe for water use. seamless steel pipe, bright seamless steel pipe, seamless steel pipe for military medical, seamless steel pipe for pipeline, seamless steel pipe for pillar and so on.
Question 6: What is the meaning of the indoor steel pipe and outdoor steel pipe inside the quota 1, first of all, distinguish between DN350 hot dipped galvanized seamless steel pipe is a process pipeline, or water supply and drainage pipe, or air conditioning pipe.
2, process piping set with the sixth book, drainage and air conditioning piping (in addition to the air conditioning room) set with the eighth book.
3, indoor installation refers to: that is, from indoor to outdoor 1.5 meters or the first valve well all the pipeline, indoor steel pipe welding connection quota in the DN350 specification. I think: you can refer to DN300, change the main material, proportionally adjust the auxiliary materials.
4, if the outdoor pipeline, another calculation of the excavation and filling can be, this has DN350 quota.
Issue 7: galvanized steel pipe diameter greater than 200, set what quota There is no pipe flange connection quota, you can use steel pipe welding (threaded, if the case of threaded flange) + flange connection practice. Here it should be noted that, inside and outside the hot-dip galvanized steel pipe if welding, welding needs to be galvanized twice, here will occur dismantling, transportation, secondary galvanizing, secondary installation costs
Question 8: steel-plastic composite pipe set what quota Installation budget quota within the water supply and drainage chapter booklet inside the indoor steel-plastic composite pipe (threaded connection) of the quota, if there is no quota in your province, you can borrow galvanized steel pipe quota, the main material, the main material, the main material, the main material, the main material, the main material, the main material, the main material, the main material, the main material. Steel pipe quota, the main material conversion
Question 9: How to set the quota of buried steel pipe laying you say specific? Is it directly outdoor buried laying or indoor concrete structure buried laying?
Question 10: stainless steel pipe set what quota installation quota seamless steel pipe project, if it is an indoor project, the set of welded steel pipe, adjust the price over the
