Pipe fittings



Pipe fittings are work that involves the installation or repair of pipes or tubes. Pipes and tubes are necessary for a wide range of reasons.
We are passionate about elbows, tees, reducer …

Pipe elbows
Pipe elbows >>
Steel elbow is used to be installed between two lengths of pipe or tube allowing a change of direction,usually these carbon steel elbows distinguished by connection ends.

+ Long radius + Short radius

Bending
Pipe bending >>
Pipe bend can be made of variety materials,like carbon steel,alloy steel,stainless steel,low temperature steel or high performance steel,etc.

+ 180 degree bending   + ASTM API 5L Gr.B bends 

Pipe tees
Pipe Tees >>
We can provide seamless tube tees and welding tube tees,which can also be divided into straight tees and reducing tees.Usually,the pipe tees have the same inlet and oulet sizes.

+ Reducing tee   + Barred Tee   + Stainless Steel Tee

Pipe cross
Cross >>
A pipe fitting, having four openings in the same place, at right angles to each other.



End caps
End caps >>
End Cap, Carbon Steel cap, Stainless Steel Caps, ANSI, ISO, JIS and DIN Standards, Measures 1/2 to 56 Inches.

+ Large size end caps  + Carbon steel end caps

Pipe reducer
Pipe reducer >>
Pipe reducer are tube fittings that are widely used in a number of industries in order to providing greatest connection flexibility in connecting fractional tubes in various installations.

+ Concentric reducer  + Eccentric reducer

Stub end
Stub end >>
Stub Ends are fittings used in place of welded flanges where rotating back up flanges are desired. They are also called Lap Joints and Vanstone Flared Laps. A rotating back up flange seats itself against the back surface of the Stub End.

+ Stainless stub end   + Carbon steel Stub end

Coupling Fittings
Coupling Fittings >>
Coupling fittings are used for fluid conduits in which each end portion of two tubes to be connected is provided with a swaged-on adapter carrying the necessary means to connect or disconnect the tubes without disturbing the swaged-on adapter.

We have a team of experienced professionals with years of experience in manufacturing.
What exactly do you mean by pipe fittings?
Different from the tranditional process technique, we don't acid pickling at the last 2 steps, but directly bright annealing at the optimum temperature. Advantage: Guarantee the accurate thickness, smooth and balanced bright of both inside & outside surface
Pipe Fittings End Beveling
Pipe elbowsIn the behavior, we make beveling after shot blasting, bevel ends are fully machined by advanced equipment Double Beveling Machine ensure the height, length, thickness, O.D. and I.D. are all qualified.
Welding Bevel acc. to
Delivery requirment:
Marking: SunnySteel, material grade, standard, specification, heat no.
Surface Treatment: Bright annealed, polished outside and inside surface.
Package: Each pipe in a PVC bag and caps on both ends then bundled in wood case, (option: Bundle with knitted plastic bag/stee crate. )
Mill test certificate: according to EN 10204 3.2
Inspection:
Third party inspection, or by clints
Fittings prologue >>
Pipe fittings are made from pipes, plates and forging material, which are used to change of direction & connected pipe size and diverge from main piping service.

The material of the stainless steel round bar is from Jiuli and Baosteel China, we control the quality from the very start. We polished three times to make sure the surface is perfect bright and smooth, and without any deficiency in quality. We have precision equipment to test according to the standard required and PMItest to check the material before delivery.
Note: PMI(Project Management Institute)

ANSI/ASME B16.25 standard specification

ANSI/ASME B16.25 is the standard covers the preparation of butt welding ends of piping components to be joined into a piping system by welding. The standard includes the butt welding ends information of General scope, Welding Bevel designs, Preparation of inside diameter of welding ends and the tolerances involved. ANSI/ASME B16.25, Buttwelding Ends Following are the dimensions of the butt welding pipe ends according to ANSI B16.25. It includes requirements forwelding bevels, for external and internal shaping of heavy-wall components, and for preparation of internal ends (including dimensions and tolerances). Coverage includes preparation for joints with the following: (a) no backing rings (b) split or noncontinuous backing rings (c) solid or continuous backing rings (d) consumable insert rings (e) gas tungsten arc welding (GTAW) of the root pass Details of preparation for any backing ring must be specified when ordering the component. ANSI/ASME B16....

How to Calculate a Pipe Bend?

Pipe fittings are necessary to join together pipes, or to change the direction of an existing pipe. Pipes and pipe fittings are made of a variety of materials, depending on the fluid or gas being transported. Most pipe fittings tend to be either threaded or able to slip over the pipes they connect. Whether you are using steel pipes of PVC pipes, a chemical solvent is required to create a seal between the pipe and the fittings. Calculate a Pipe Bend Measure the required length of the pipe to be installed, keeping in mind the extra length required where the pipe will be inserted into the fitting. Mark this length on the pipe. How to Calculate a Pipe Bend Whether you are bending pipe for running electrical conduit or a metal project, calculating the bend for the start and end point can be an important factor. While there are different types of pipe benders on the market, they all share a common identification for the operation. Identified on all pipe benders is the size of pipe the unit w...

ANSI Flange Standards

The American National Standard Institute, ANSI, has been overseeing guidelines and standards for products manufactured through several sectors. WHAT IS ANSI? ANSI-approved flanges are used for the industrial market which handles gas, air and steam process systems. Originally formed in 1918, the American National Standards Institute is headquartered in Washington, DC, and is widely recognized as the American organization responsible for overseeing the national standards and conformity assessment system for products, services, processes, systems, and personnel. ANSI works domestically with American government agencies and organizations, as well as with international entities, to make ANSI standards useful around the world. Prior to the creation of ANSI, standards for engineering and equipment such as flanges were developed by the American Institute of Electrical Engineers (AIEE or IEEE), the American Society of Mechanical Engineers (ASME), the American Institute of Mi...
