5) FAQ

We have organized several common questions for our clients,may help you sincerely:

①How about your company?

One of the leading manufacturers and suppliers specializing in steel pipe products in China, mainly offering four series steel pipes including welded steel pipe (ERW, SSAW, LSAW and square and rectangle pipe), seamless steel pipe, hot dipped galvanized steel pipe and steel pipe with 3 layer polythene coating. We can provide customers different specification standards e.g. ASTM A53, ASTM A106, BS1387, API 5L, API 5CT, ISO3183 and etc. Our scope of supplying covers from 1/2" to 48"  for the outside diameter of welded pipes, and 1/8" to 20" for the seamless pipes.


Other than steel pipes we are also capable of supplying a wide variety of pipeline accessories, steel pipe fittings; valves etc. consists of our one-stop sales. The integrated sales & service ensures customers with various demands an easier access for purchasing management.

②How to guarantee the quality of the products?

We have established the international advanced quality management system,every link from raw material to final product we have strict quality test;We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.

Q:What are the connecting forms of industrial pipe joints? Like buckling type connection,
Working pressure of quick joint: 1.6Mpa. Temperature: -54 ~ 180 C. Working medium: gasoline, kerosene, heavy oil, hydraulic oil, fuel oil, frozen oil, water, salt, acid and alkaline liquid, high pressure gas etc.. Material: stainless steel, copper, Aluminum Alloy. Sealing material: NBR rubber, polyurethane, silicone.
Q:About thread, pipe joint standard question
For thread purposes, you are recommended to study the metric, American and American thread standards manual
Q:What are the specifications and models of metal hose couplings?
The utility model is mainly used for the embedded pipe with small dense gap, small diameter inserted in the steel pipe and convenient installation.5, mainly used for steel pipe and metal hose caliber inconsistent circumstances, according to field installation requirements arbitrarily increase and decrease the small change joint.
Q:How much is the monofilament of the 304 pipe joint?
If it is conventional, the basic can be connected, Sheng Jiang Industrial products have such joints, called water pipe joints
Q:What's the difference between pipe repair device and clamp type flexible pipe joint?
Stainless steel pipe repair machine, plate repair machine mainly adopts 201 stainless steel manufacturing, suitable for low pressure pipeline, the general scope is 16 kg, can not solve the problem of limit, limit will not be able to solve problems of flexible axial compensation.The clamp type flexible pipe joint needs welding, but the pressure range is big, 10-220 kilograms of pressure can bear, and it has the limit function, at the same time provides the effective flexibility and the corner to the limit. The utility model is generally used on pipelines of more than 16 kilograms, and the cost is greatly lower than the flanges and the telescopic devices.Two kinds of pipe fittings can not be said which is easy to use, in the right place to use.
Q:Can the pressure vessel pipe joint adopt G thread? Why?
The pipe thread is on the wall of the pipe for connecting threads. It has 55 degrees of unsealed pipe thread and 55 degree sealing pipe thread. The utility model is mainly used for the connection of pipelines, and the internal and external threads of the utility model are closely matched with two kinds of straight pipes and a conical pipe
Q:Consult the problem of the pressure at the entrance and exit of the pipe joint
Assuming two load infinite, a 1MPa load (cylinder or motor) can free action, three exits are linked together, so that the two load does not move, a move, three oil outlet pressure gauge pressure is 1MPa.Assume that one or more of the three is not loaded, and the three outlet pressure is 0, or very small. The three outlet pressure gauges are 0MPa.,You don't design, I'm scared
Q:Requirements for fire hose fittings
4.3.3 thread connection(1) the galvanized steel pipe with inner diameter of less than DN100 and hot-dip galvanized seamless steel pipe both inside and outside wall can be threaded. When using internal and external wall of hot galvanized steel pipe, the pipe can be used malleable iron threaded fittings (GB3287-3289); when the system adopts internal and external wall of hot galvanized seamless steel pipe, the pipe can be used forged steel threaded pipe fittings (GB/T14626).(2) steel tube wall thickness is smaller than DN50 shall not use thread movable joint, and single variable diameter joint shall be adopted at reducing diameter of pipe.4.3.4 welding or flanged joint(1) according to the flange type connection form can be divided into: flange, welded flange and threaded flange etc.. Flange selection must comply with steel pipe flange (GB9112-9131), steel welded seamless pipe (GB/T12459), pipe flange with Teflon coated gasket (GB/T13404) standard.(2) if hot-dip galvanized steel pipe adopts flange connection, threaded flange shall be used. The system pipe adopts the inner wall without corrosion, and the pipeline can be welded and connected. Piping welding shall be in accordance with the specification for construction and acceptance of welding equipment for field equipment and industrial piping (GB5036).
Q:Connect with stainless steel tube with 304 stainless steel clip type pipe joint,
Because it is clamping, used for steam to consider the impact of temperature, it is not recommended for toxic, harmful, medium pressure above the high temperature gas.
Q:What joints do nylon hard tubes work on?
The pipe joint is the connecting tool between the pipe and the pipe, and it is the connection point between the component and the pipe.There are three kinds of hard tube joints: flaring, clamping and welding
