ASTM A815 Duplex Steel 90 degree pipe elbow suppliersASTM A815 Duplex Steel 90 degree elbow is a type of Duplex Steel Buttweld Pipe Fitting which you can used to change the flow direction in a 90 degree. It is also called “Duplex Steel 90 Bend” or “Duplex Steel Quarter Bend”. As a joint between two pipes, the 90 degree elbows are also used as a railing ends or corners on a level installation. ASTM A815 Duplex Steel 90° Elbows are made of Duplex Steel seamless tubes within the diameter range of DN 15 – DN 1000.
We supply our welded and seamless pipe elbows with all the standard approval test certificates according to EN 10204 with certification in compliance with DIN/EN and/or VdTÜV material sheets or corresponding ASME.

ASTM A815 Duplex Steel 45 Degree Elbows suppliersASTM A815 Duplex Steel 45 degree elbow is the Duplex Steel elbow which can change the flow direction in a 45 degree. As a joint, it is used between the two pipes which has this right angle. ASTM A815 Duplex Steel 45° Elbows are made of Duplex Steel seamless tubes within the diameter range of DN 15 – DN 1000.
The ASTM A815 Duplex Steel 45 degree butt weld elbow is a pipe fitting that is attached to two pieces of pipe to allow a change in direction. ASTM A815 Duplex Steel butt weld elbows can come in various degrees of angles and schedules. The most common angles available are 45 degree elbows and 90 degree elbows. ASTM A815 Duplex Steel 90 degree elbows are available in long radius and short radius. The schedule corresponds to the wall thickness of the pipe. The function of a pipe is to carry gasses or fluids under pressure. Therefore, the ID, or internal diameter of the ASTM A815 Duplex Steel butt weld elbow is a major dimension of the pipe. A pipe’s outside diameter (OD) remains comparatively constant for all pipe sizes. It is the inside diameter’s (ID) bore size that is reduced as the schedule or wall thickness increases.
ASTM A815 Duplex Steel 180 Degree Returns suppliersThe recommended procedure for a 180 change in direction is to use a formed 180 return fitting rather than combine two 90 elbows or field fabricate a 180 pipe bend from a straight pipe piece. ASTM A815 Duplex Steel Returns are used primarily in heater coils and heat exchangers. The number of coils the space has available determines whether a short or long radius return is desirable. All ASTM A815 Duplex Steel long and short 180 radius returns have center-to center dimensions that are double those of matching 90 elbows.

ASTM A815 Duplex Steel Reducing Tee suppliersA tee is a branched, reinforced outlet fitting that permits flow at 90 to the main flow. The main flow passes through the run of the tee. The 90 outlet is called the branch of the tee. ASTM A815 Duplex Steel straingt tee is manufactured with all three outlets, the run as well as the branchm the same size. ASTM A815 Duplex Steel reducing tee is made with the branch outlet smaller than the run to accoomodate the design flow rate.
We offer a wide range of tees in our product range, from DIN 2615-1 to AD 2000-W2 and VdTÜV 421 to ASTM/ASME A/SA 815 / 403. Other specific dimensions and shapes can be supplied within a short time time, some from our own production.
Straight / Reduced
ASTM A815 Duplex Steel Pipe Tee suppliersOur ASTM A815 Duplex Steel butt weld pipe tees include ASTM A815 Duplex Steel butt weld straight tees and ASTM A815 Duplex Steel butt weld reducing tees. ASTM A815 Duplex Steel tees are available within the range of DN 15 – DN 600. Our ASTM A815 Duplex Steel butt weld reducing tees meet strict certifications required on current piping systems with qualities of high strength and SS corrosion resistance for use in various industries and environments.
The most common pipe fitting is an pipe tee or specifically an ASTM A815 Duplex Steel straight pipe tee. ASTM A815 Duplex Steel Tees have two outlets at 90 degrees from the main flow and are used to combine or split fluid or gas flow. ASTM A815 Duplex Steel Tees connect and combine pipe systems or they can connect various size pipes together with reducing tees. ASTM A815 Duplex Steel reducing tee can connect various sizes of pipes together in one pipe system.
ASTM A815 Duplex Steel Pipe Reducer/ Reducers suppliersWe can manufacture two kinds of ASTM A815 Duplex Steel pipe reducer: ASTM A815 Duplex Steel concentric reducer and ASTM A815 Duplex Steel eccentric reducer. Which are commonly used to change the pipe size or pressure in a piping system. ASTM A815 Duplex Steel reducers are made of Duplex Steel seamless tube within the range of DN 15 – DN 1000.
ASTM A815 Duplex Steel butt weld pipe reducer enables there to be a change in pipe size to meet certain hydraulic flow requirements or sometimes it’s just a matter of connecting two different pipe sizes. ASTM A815 Duplex Steel eccentric butt welding reducer is a type of Duplex Steel pipe fitting that is used when a pipe on the upstream side of the fitting is larger than the downstream side of the fitting. ASTM A815 Duplex Steel concentric butt welding reducer works the same way, but resembles a cone and keeps fluid or gas more centered, whereas ASTM A815 Duplex Steel eccentric reducers have a parallel edge, which results in an offsetting center. ASTM A815 Duplex Steel Eccentric butt weld reducers are used if the same top or bottom level of the pipe is required.
Our delivery standard includes all the standard approval test certificates according to EN 10204 with the certification of reductions according to DIN/EN. We also carry items that comply with the VdTÜV material sheets or ASME:
ASTM A815 Duplex Steel Eccentric Pipe Reducer/ Reducers suppliersThe eccentric reducer has the reducing outlet end off center. It will line up straight with one side of the inlet but not with the other outlet. This reducer is harder to manufacture than the concentric reducer and costs more.

ASTM A815 Duplex Steel Long Radius Pipe Elbows suppliersGenerally, their size designations are either long radius or short radius. The ASTM A815 Duplex Steel long radius elbow is usually adequate for standard service conditions. The center-to-end dimension is always 1-1/2 times the nominal size of the elbow. ASTM A815 Duplex Steel Short radius elbows have a center-to-end measurement equl to pipe diameter.
ASTM A815 Duplex Steel long radius elbow costs less than a short radius fittings. ASTM A815 Duplex Steel Long radius elbows offer minimum resistance to flow consistent with space savings and presently account for more than 90 percent of all elbows in use.
Materials: ASTM A815 / ASME SA815 Thickness : Sch 5s, Sch 10s, Sch 40s, Sch 80s, Sch 160s, Sch XXS
ASTM A815 Duplex Steel Short Radius Pipe Elbows SuppliersWhen space is limited and the flow rate is non-critical, an ASTM A815 Duplex Steel short radius elbow is often selected. When fluids are moved long distances or must encounter many directinal changes, short radius elbows are not recommended because of their greater friction loss, which may require installation of larger pumping equipment.

ASTM A815 Duplex Steel Pipe Cap/ End Cap suppliersASTM A815 Duplex Steel heads/ Pipe Cap are available within the range of DN 15 – DN 500. Our high-quality and corrosion resistant ASTM A815 Duplex Steel butt weld caps come in various sizes and schedules to fit your Duplex Steel pipe and fitting needs.
ASTM A815 Duplex Steel butt weld cap is a type of Duplex Steel pipe fitting that covers the end of a pipe. Since it can have female threads, it can screw on to the male end of the pipe. It can also be welded on to close the end of the pipe. On a weld, if it is a temporary close, or the contractor wants to add to the piping system in the future, he or she should allow additional pipe before closing so the pipe cap can be cut off and the pipe system extended as needed. This way you will not have less pipe than you need and the new fitting can be attached correctly.

We can carry out short-term additional tests to individual customer specifications and also provide certification.
ASTM A815 Duplex Steel Stub End suppliersThese ASTM A815 Duplex Steel fittings are used in lines that might require a quick-disconnect system. They are also used to facilitate lining up the bolt holes of flanges when there flanges are now welded or fastened to the pipe. Normally, ASTM A815 Duplex Steel stub ends are installed in pairs, the paired fittings mating with two lap joint flanges. This allows wasy opening of the line for future cleaning and inspection and if the line requires replacement, the flanges can be reused because they are not fastened to the system. They ride freely in the outside of the pipe. ASTM A815 Duplex Steel Lap joint stub ends are made with serrated gasket surfaces for improved sealing of the connection and prevention of leakage at the joint. This surface has replaced the raised gasket surface of a flange.
