Q:What's the gate number of the precision steel pipe?
Precision steel pipe refers to the high precision steel pipe, the wall thickness and internal and external diameter can be controlled within 10 wire tolerance range
Q:How to distinguish between steel pipe and spiral pipe material?
Steel pipe according to the pipe material (ie steel) can be divided into: carbon tube and alloy tube, stainless steel tube.Carbon tube can be divided into ordinary carbon steel tube and high quality carbon structure tube.
Q:Is it good to buy a simple wardrobe or a steel pipe?
If the home place is big, buy Wooden, good-looking durable, if the place is small, buy cloth, easy to receive, mobile, tidy and cheap.
Q:Theoretical weight of 25*25*1.5 square steel tubes
Square steel tube, referred to as square tube, also known as square tube, is a square pipe of a kind of name, that is, the length of the same steel pipe. The strip is rolled by process. Generally, the strip is disassembled, leveled, crimped and welded to form a round tube. The tube is then rolled into square tubes and cut to the required length, usually 50 pieces per package.
Q:What kinds of steel pipe are divided into?
The steel pipe seamless steel pipe and welded steel pipe (tube) two categories. According to the section shape and can be divided into round tube shaped tube, round steel pipe is widely used, but there are also some square, rectangular, semicircular, hexagonal, triangular, octagonal shaped steel tube.Seamless steel pipe: seamless steel pipe is ingot or solid billet made by capillary hole, then hot, cold or cold drawing. Made of seamless steel pipe specifications with outer diameter * wall thickness mm. Number of seamless steel pipe cold and hot points of seamless steel pipe (DIAL) two categories.
Q:A333gr6 steel pipe and domestic material of the same?
The SA333 standard in ASME (cryogenic seamless and welded nominal steel tubes), so A333-6 is a representation of the United States, followed by many countries.
Q:Where is the difference between seamless steel pipe and welded pipe?
Seamless pipe pressure is higher, welded pipe is generally in 10 or so MPa, now welded pipe to do seamless processing.
Q:Is the diameter of the steel tube indicated by the outer diameter by the wall thickness or by the inside diameter by the wall thickness?
Seamless steel pipe specifications are: outer diameter, wall thickness, material. Three of these reflect its main features.Welding pipe specifications are: nominal diameter (internal diameter), galvanized or non plated
Q:What time what time for gas pipeline steel pipe PE pipe
PE pipe must be installed underground, the steel tube can be exposed, when not all PE pipe for pipe laying, overhead installation. But the steel tube is easy to rust, so it can be used where the basic use of PE pipe buried PE pipe.There are galvanized steel pipe and seamless steel pipe, galvanized pipe can only be used for low-pressure homes
Q:Can galvanized pipe be welded with seamless steel tube? What should I do to connect?
See the galvanized pipe and seamless steel pipe steel that differences in how if the difference is too large then the steel used for two kinds of materials for welding requirements is not the same, do not recommend direct welding, low pressure can be used in high voltage wire, welding on both sides of the same material flange with flange connection.
