FAQ:

Q1: Why buy Materials & Equipment from OKorder.com?

A1: All products offered byOKorder.com are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, OKorder.com adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.

 

Q2: How do we guarantee the quality of our products?

A2: We have established an advanced quality management system which conducts strict quality tests at every step, from raw materials to the final product. At the same time, we provide extensive follow-up service assurances as required.

 

Q3: How soon can we receive the product after purchase?

A3: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.

 

Q4: What makes stainless steel stainless?

A4: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

 

Q5: Can stainless steel rust?

A5: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

 

Q6: What is the difference between galvanized steel and galvalume steel?

A6: Galvanized steel is metallic coated with Zinc in various coating weights. Minimum recommended for painted metal roofs is G90. Galvalume is a zinc and aluminum coated steel that becomes an alloy and is recommended in either painted or bare applications with a minimum coating weight of AZ50. Galvalume has an excellent performance life in bare exposures. Hence if you are using a bare panel use galvalume and if painted use either.

 

Q7: Is there a difference in thermal conductivity between stainless steel and steel?

A6: Yes. Stainless Steel has a lower thermal conductivity rate than steel; approximately 1/3 to 1/5th depending on the material.

 

Q8: Is there a difference in electrical conductivity between stainless steel and steel?

A8: Yes. Steel is generally more conductive than stainless steel. Steel has resistivity in the range of 10~20Ωm, while stainless has a resistivity of approximately 60~72Ωm.

Q:Are the welded and galvanized tubes the same weight?
The difference is that because zinc has weight, even if the difference is very small, there are also differences,Galvanized pipe weight is basically the same about 1.06 of the welded tube, of course, you can artificially ignored.
Q:What's the gate number of the precision steel pipe?
This kind of steel tube and ordinary hot-rolled seamless steel pipe and cold drawn seamless steel tube in the outer surface is different from the outer surface, and the diameter of the smooth finish of precision steel tube, stainless steel color and the same, inside and outside surface due to manufacturing reasons with a layer of oil.
Q:What is the difference between seamless steel pipe and welded pipe?
Such as hydraulic equipment pipeline connection. The weld seam of common steel pipe is its weak link, and the quality of weld is the main factor that affects its overall performance. People who have lived in the north have experienced the experience of freezing pipes and pipes in winter, and the places where they burst are usually welds. Welded pipe is not seamless steel pipe.
Q:What is the outer diameter and wall thickness of the welded steel pipe of national standard DN250?
DN (nominal diameter) 250 is generally the industry said 273, welded steel pipe (spiral steel pipe) thickness is generally between 6-8mm, more common.
Q:What's the material of Q325 steel pipe?
Q235 refers to the material yield stress of 235MPa carbon steel, because of its low price, good machining and welding performance, it is generally used for welding structural parts. Of course, the unimportant parts can be used for it.
Q:304 stainless steel tube with the diameter of 25*2-3 is what mean
304 stainless steel tube with the diameter of 25*2-3 said: material for 304 (the equivalent of the American brand, Chinese numbered S30408 stainless steel or 06Cr19Ni10 stainless steel), diameter (OD) for 25mm, for the seamless steel pipe wall thickness of 2 to 3mm.
Q:Are there specifications for scaffold steel pipe with 48mm * 3.2mm?
Scaffold tubes are our name for materials used to build scaffolding, because most scaffolding uses tubular bamboo or steel tubing. Bamboo and other bamboo is for a long time in the use of the scaffolding tube, but due to lack of safety and durability, now only in rural and urban area construction is lagging behind some of the home building small building has been used. The modernization construction, the most commonly used type of scaffolding pipe is steel pipe, the scaffolding should not only meet the demand of workers, but also to meet the characteristics of scaffolding firm and durable, so tough hard steel is the best choice. The selected steel pipe generally requires smooth surface, no cracks, no bending, no rust, and meet the relevant national standards.
Q:What is the difference between hot dip galvanized steel pipe and galvanized steel pipe?
Galvanized steel pipe is commonly known as "cold plated tube", using electroplating process, only galvanized steel pipe in the outer wall, the wall of the pipe is not galvanizedHot dip galvanized steel pipe adopts hot-dip galvanizing process, and the inner and outer walls of the steel pipe have zinc coating.
Q:What is a tight steel tube?
JDG pipe is the replacement of traditional PVC and SC pipes and other traditional wire conduits. It is a breakthrough in the field of building electrical field using new materials and technologies. The JDG pipe adopts the cross connecting ground wire of galvanized steel pipe and thin-wall steel pipe, overcomes the defects of complicated construction and large construction loss of common metal pipe, and solves the problems of poor fire resistance and difficult grounding of PVC pipe. Because the JDG pipe material is more expensive than the ordinary pipe material, it is more used in the construction, such as comprehensive wiring, fire protection wiring and so on.
Q:What does "steel pipe SC" mean?
SC is an ordinary welded pipe, equal to water professional DN, SC is welded steel pipe concealed, general pipe wall is relatively thick, S represents pipe material, C represents laying mode, TC stands for wire pipe concealed, pipe wall is thinner.
