What is the correct installation method for stainless steel flanges? 1. the stainless steel flange should have sufficient strength and not deform when tightened. The flange sealing surface should be flat and clean, and the oil stains and rust spots should be carefully cleaned up when installing the stainless steel flange. 2.the gasket should have […]
Carbon steel weldability and its test evaluation 1. Welding: A process in which two objects are combined between atoms to form an inseparable whole by heating or pressing, with or without filling materials. 2. Weldability: refers to the ability of homogeneous or dissimilar materials to be welded to form a complete joint and meet the […]
What are the technical requirements for elbows in engineering projects? 1. Since most of the pipe fittings are used for welding, in order to improve the welding quality, the ends are beveled, with a certain angle and a certain side. This requirement is also strict, how thick the side, how much angle and deviation The […]
Butt welding flange is a kind of pipe fittings, which refers to the flange with neck and the transition of round pipe and butt welding with the pipe. Butt welding flanges are not easy to deform, have good sealing, and are widely used. They have corresponding rigidity and elasticity requirements and reasonable butt welding thinning […]
Wear-resistant ceramic pipes are widely used in the industrial field, especially in high-wear working environments, such as power plants, cement plants, mines and other enterprises. Wear-resistant ceramic pipes reflect the incomparable advantages of other products. Wear-resistant ceramic pipe connection method 1. Fixed flange connection Fixed flange connection means that the flange is directly welded to […]
What is a bimetal composite wear-resistant pipe? The outer wall of the bimetal composite wear-resistant pipe is made of ordinary seamless steel pipe, which is compounded by a high-chromium cast steel lining through a centrifugal forming process. The outer wall of the elbow is made of shrimp elbows, and the inner layer is made of […]
The outer wall of the bimetal wear-resistant composite pipe is made of ordinary seamless steel pipe, which is compounded by a high chromium cast steel lining through a centrifugal forming process. The outer wall of the elbow is made of shrimp elbows, and the inner layer is made of high-chromium cast steel, which not only […]
What is the difference between PTFE lined pipe and rubber lined pipe? Tetrafluoro is a polymer of tetrafluoroethylen, short for PTFE. Polytetrafluoroethylene (Poly tetra fluoroethylene, abbreviated as PTFE), is generally called “non-stick coating” or “easy to clean material”. This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all […]
Steel-lined PTFE pipe is a kind of green plastic pipe with the most anti-corrosion, wear-resisting, energy saving and environmental protection. Its wide application has accelerated the process of new environmental protection roads in mines to a certain extent. It not only realizes the low-carbon and environmental protection of mine operation, but also saves cost and […]
1. The principle of self-propagating ceramic composite pipe: The ceramic composite pipe is manufactured by self-propagating high temperature synthesis + centrifugal casting, that is, the seamless steel pipe is placed in the tube mold of the centrifuge, and the thermite (a mixture of iron oxide powder and aluminum powder) is added to the steel pipe, […]
