1.Q: How long time your company has been in business? A: We are manufacturer of construction materials for 20 years in steel industry. 2.Q: Can I have a trial order only several tons? A: Of course. We can ship the cargo for u with LCL service. (Less container load) 3.Q: Do u have payment superiority? A: For big order, 30-90 days L/C can be acceptable. 4.Q: Do you have mill certificate and material component analysis report? A:Yes we have professional quality analysis department. We supply quality report for each batch goods.Seamless steel tube used in machining is one of the most commonly used types of seamless steel tube. Seamless steel pipe has hollow section, no weld from top to bottom. Compared with round steel and other solid steel, seamless steel tube has the same bending and torsional strength, and the weight is lighter. It is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, bicycle frame and steel scaffolding used in construction. Mechanical tubing application Tubing used for mechanical and light gauge structural applications.Mechanical tube is produced to meet specific end use requirements, specifications,tolerances and chemistries. This allows for more specific property uniformity throughout the tube compared to standard pipe or tube.While Mechanical tube can be produced to standard specifications when requested, it is often produced to“typical" properties that focus mainly on the yield strength for a precise size and wall thickness. in some applications with severe forming, yield strength may not even be specified and the mechanical tube is produced to be "fit for use". Mechanical tubing encompasses a wide range of both structural and non-structural applications. Mechanical tubing type Mechanical tubing is manufactured to typical mechanical tube properties in accordance with ASTM A513 and ASTM A519 specifications. Some of the most common types of mechanical tubing are Drawn Over Mandrel tubing(DOM),Hot Rolled/Finished Seamless tubing(HRS),Cold Drawn Seamless tubing(CDS),Hot Rolled or Cold Rolled Electric Weld tubing(HREW/CRFW),and 4140 Alloy tubing.Mechanical tubing is not limited to these specifications and can be produced to exact customer requirements when appropriate. Mechanical products are ordered to a specific outside dimension(OD)and "gauge" or wall thickness or by outside dimension(OD)and inside dimension(ID).Additionally,most mechanical tubing can be available in galvanized as well upon request.OD:38.1mm~12-3/4”323.8mm
