The necessity of suction armor and suction truck chassis armor: Sewage suction trucks and suction truck chassis do not see sunlight all the year round, and they are constantly faced with embarrassment, collisions, and threats of corrosion and corrosion. The chassis also directly affects the use of vehicles, although car manufacturers will take into account the height of the ground and do some degree of chassis protection when producing cars. However, the diversity of vehicle environments determines that these measures do not fully guarantee the safety of the vehicle chassis. How to determine whether the sewage suction truck or suction truck should be chassis armored: Since the protection of the chassis of each brand model is different, it is the most basic method to view the car up. If there is a layer of rough plastic on the bottom of the car, the press is flexible, indicating that it is protected. If it is a smooth bare steel plate, it means no protection. During the inspection, special attention should be paid to the protection of the car's wheel arc, the inner side of the fender, and the connecting steel frame. These key parts are usually missed by the manufacturers. Types of chassis armor: 1. Chassis anti-rust rubber with asphalt components. This is the first generation of chassis armor products that have been eliminated in the market. 2, oily (solvent) chassis anti-rust rubber. This is the second generation of chassis armor products, in which the diluent is mostly toluene, which is a highly toxic ingredient that is harmful to the human body. The adhesive layer formed after the construction is very hard, easy to crack, and the sound insulation effect is also very general. 3, water-soluble chassis anti-rust rubber. Also known as environmentally friendly chassis anti-rust rubber, most of them are currently used in Europe and the United States. The water-soluble chassis anti-rust rubber has strong adhesive force, good elasticity of the rubber layer, and soundproof effect of the chassis. It is the preferred material for making chassis armor.
Coupling
Tubing and casing couplings are the joining of two short length pipe, mainly used for the connection and repair of oil pipe and downhole tools
Tubing and couplings thread types : Non-upset thread(NU), External- upset thread(EU);
Casing and couplings thread types: Long-round thread(LC), Short-round thread(SC), buttress thread(BC)
Grade: K55,J55,N80-1,N80Q,L80-1,P110,etc.
Pup joint
Tubing and casing pup joints are machined according to the latest version of API SPEC 5CT. The steel grade includes J55,K55,N80-1,N80Q,L80-1,P110,etc. There are two types of thread widely used in tubing pup joint namely Non-upset thread(NU), External- upset thread(EU);
Casing and couplings thread types: Long-round thread(LC), Short-round thread(SC), buttress thread(BC).
Our testing and inspection method system is complete, using a whole set of thread instrument to inspect taper, pitch, tooth, height, tooth type,etc. The products have passed the identification of china petroleum pipeline. Quality supervision ,inspection and testing center and gained the unanimous praise from the customers.

“Chassis armor†is a new project for chassis rust care in recent years. It is spraying a layer of 2–4 mm thick elastic sealing material on the underside of the car chassis, just as if the chassis of the car is put on a thick layer of armor. Chassis armor is an image description of this technology.
