Q:PVC can the pipe joint be butted with the joint? How do I get it?
One is welding, the other is adhesive bonding, and the other is double headed thread connection
Q:What is a reinforced pipe joint?
It has a certain mechanical strength and good shock absorption. It is suitable for making parts under moderate stress, working parts in weak corrosive environment, such as cover, bearing seat, valve body, hand wheel and so onThe main purpose of strengthening the pipe joint is to connect, install and maintain conveniently.
Q:Inside and outside the threaded joint, one end of the internal thread (G),
G is the British characteristic of non hermetic cylindrical thread.The thread tagging you can refer to "metric, American and English standard thread Standard Handbook (Third Edition)".
Q:Will that be all right? Then there's the PPR pipe joint on the right. Is that ok?
The theory of PPR hot melt connection is safe and reliable, more than a few joints do not affect the use, will not cause the day after Water Leakage, of course, the premise is the quality manual, technical standard master.
Q:Reinforced pipe joint,Used in chemical pipes
D means "diameter", and "n" means "internal" (because pinyin is "Nei" in "inner")
Q:What are the types of tubing and pipe couplings applicable to each occasion?
Pipe joint is detachable between the tubing and tubing, tubing and hydraulic components of the connection, it should satisfy the convenient assembly and disassembly, reliable connection, reliable sealing, small size, large capacity oil, small pressure loss, good processing etc.. According to connection tubing and pipe joints, pipe joints are welded, sleeve type, expanding type, press type form; pipe joints each form, according to the channel number and direction of joint points straight, rectangular, three other types; threaded connection and flange connection with the connection of the body. In addition, there are some special purpose pipe couplings.
Q:What's the difference between pipe repair device and clamp type flexible pipe joint?
Generally applicable range is less than 16 kilograms, can not solve the limit problem, limited position can not solve the problem of flexible axial compensation.
Q:What's the hydraulic pipe joint material?
Chemical equipment piping usually walks a variety of corrosive fluids, the need for frequent use of solvent or water rinse. Therefore, the general chemical line must be stainless steel.While thinking about medium corrosion. We should consider the relation between pipe seal and medium. Ding Qing rubber is commonly used in hydraulic systems because it is miscible with ordinary hydraulic oils. Ding Qing rubber at a certain temperature, but also with the synthesis of acetaldehyde, sugar chemical liquid (HEPG) and the proposed plant in liquid and compatibility, nitrile rubber (NBR) is not suitable under high temperature and acidic medium, benzene or synthetic oil, then should use fluorine rubber (FKM), on the contrary, methane and refrigeration only with ammonia NBR (NBR) miscible, so most chemical stainless steel pipeline are rigid seal.
Q:Outside the wire (wire) of what the standard joint size
The metal joint is made of zinc alloy. The surface is zinc plated, sanded or chrome plated. The structure is close, without porosity and high strength. Reliable connection with metal hose, beautiful appearance;The metal joint is an end connection and a linear connection for connecting the metal hose to the case;It is recommended to use an inch metal hose joint or a metric thread metal joint;Can be customized a variety of non-standard metal hose joints, special metal joints.Ferrule type metal joint
Q:Plastic pipe joint leakage, how to deal with better?
Repair seal.Specific operation, see the following points:Now that the water leaks, you'll find the main switch for this pipe and turn it off for later maintenance;
Our factory has implemented a complete quality control system, due to physical and chemical testing instruments and apparatus. Aiming at 100% customer satisfaction and eligibility ratio, our company is ISO9001 and TUV certified. We warmly welcome customers both at home and abroad to visit us for mutually beneficial business relationships.
