The position of the delivery items contained in the warehouse-type semi-trailer is a semi-trailer designed with a fence structure. The main use of most vehicles is to transport agricultural and sideline products such as fruits, vegetables, and some of the daily necessities we use in our lives, as well as other types of light-bulk goods. It is the semi-trailer Gatton tool that we often see in daily life. It is also an essential transportation vehicle in express companies and check-in stations. However, in terms of power engineering and communication engineering, the warehouse-type semi-trailer truck can also play a good role, because some of the small equipment used in the project are used warehouse gate semi-hung Transporter to transport. 1. The design and structure of the fences and models of warehouse-type semi-trailer trucks are combined with the use of the user's category of transport goods to carry out a more reasonable design. It can be satisfied that the weight of the cabin can be reduced under the condition that the load is carried out. The structure of the vehicle is also relatively simple and applicable. It is more convenient when disassembling and can reduce the investment cost for the owner. 2. The structure of the space frame welded by the longitudinal girder used for the slat -type semi-trailer and the entire cross-beam group. Such a structure can well balance the rigidity, toughness, strength, and ability of the frame of the silo-type semi-trailer truck to be carried by the vehicle, and it will not cause permanent deformation. 3. The frame of part of the gated-type semi-trailer truck is of a beam-type structure, and the stringer structure uses a goose-neck type or a flat type. The height of the web is between 400 and 500, and the welding method used for the stringer is the automatic submerged arc welding method. The frame of the vehicle is used for shot blasting, and the beam is inserted into the stringer and welded into a whole. 4. The suspension systems used in the warehouse-type semi-trailer are all new, and they have better impact resistance and high strength. The shaft load of each axis is relatively balanced, and the angle of its system pull rod is also relatively reasonable. In the process of driving, the warehouse-type semi-trailer encounters bumpy road sections and can reduce the friction between the wheel and the ground. The slip distance can well reduce the degree of wear of the vehicle tires. And can adjust the lever at the same time, adjust the wheelbase, can be a good way to avoid the occurrence of uneven wear and tear wheel.
Steel Pipe (steel pipe production technology development began on a bicycle manufacturing industry rise, the 19th century early oil development, during the two world wars ships, boilers, aircraft manufacturing, after the Second World War thermal power boiler manufacturing, chemical industry and petroleum natural gas drilling and transportation, effectively promote the development of steel pipe industry in variety, yield and quality.
Steel pipe is not only used for conveying fluid and powder solid, exchange heat energy, manufacturing machinery parts and containers, it is a kind of economic steel. The steel pipe is used to make the structure of the building structure, the support and the mechanical support, which can reduce the weight and save the metal from 20 to 40%, and can realize the mechanization construction of the factory. The construction of the highway bridge with the steel pipe can not only save the steel, simplify the construction, but also greatly reduce the area of the coating protection layer, save the cost of investment and maintenance.

According to the production method
Steel pipe according to the production method can be divided into two categories: Seamless Steel Pipe and pipe joints, pipe joints as Welded Steel Pipe.
1. Seamless steel pipe according to the production method can be divided into: hot-rolled seamless tube, cold drawn tube, precision steel tube, thermal expansion tubes, cold spinning tube and pipe extrusion.
Seamless steel pipe made of high quality carbon steel or alloy steel, hot-rolled, cold-rolled (drawn) branch.
Bundles of steel tubes
Bundles of steel tubes
2. Welded steel pipe for the different welding process is divided into the furnace pipe, welding (ERW) pipes and automatic arc welding, because of the different welding form is divided into two kinds of longitudinal and spiral welded pipe, due to the shape of the end and circular welded pipe and shaped (square, flat) welded pipe.
Welded steel pipe is rolled into a tube shaped steel plate to butt or spiral seam welding and, in the manufacturing method, voltage liquid transportation by welding steel pipe, spiral seam welded steel pipe and directly roll welded steel pipe, welded steel pipe. Seamless steel pipe can be used in a variety of industries, such as liquid pressure pipe and gas pipeline. Welding pipe can be used for water pipelines, gas pipelines, heating pipes, electrical appliances, etc..
By material
According to the material (i.e. steel pipe steel) can be divided into: carbon tubes and alloy tube, stainless steel tube etc..
Carbon pipe can be divided into ordinary Carbon Steel Pipe and high quality carbon structure pipe.
The alloy tube can be divided into: low alloy pipe, alloy pipe structure, high alloy tube, high strength tube. Bearing tube, heat resistant acid resistant stainless steel pipe, precision alloy (such as can be cut alloy) tube and high temperature alloy tube, etc..
Classification by connection
According to the pipe end connection can be divided into: light pipe (pipe end without thread) and the car wire pipe (Guan Duan with a thread).
The wire pipe is divided into: ordinary car wire pipe and pipe end upset car wire pipe.
Thick wire pipe can also be divided into: plus thick (with external thread), inside the thick (with the inside of the thread) and inside and outside the thick (with internal and external threads) and other places of the car wire pipe.
Threading pipe can also be divided into: ordinary cylindrical or conical thread and special thread, such as the wire pipe.
In addition, according to the needs of users, the car is generally equipped with pipe connector delivery.
According to the coating characteristics
According to the characteristics of surface coated steel pipe can be divided into: Clarinet (not coated) and coating tube.
The coating pipe has galvanized pipe, aluminum, chrome plated tube, alumetized tubes and other alloy layer of steel pipe.
The coating pipe is coated with an outer coating pipe, an inner coating pipe, an inner and an outer coating pipe. Commonly used coatings are plastic, epoxy, coal tar epoxy resin as well as a variety of glass type of anti-corrosion coating materials. Galvanized pipe is divided into KBG pipe, JDG pipe, screw pipe, etc.
