We are engaged in fabricating blind badges which are extensively used in varied industries such as petrochemicals, refineries, chemical, construction works, agricultural, waterworks and more. Procured from reliable vendors, we make use of good quality of raw material in the production of our gamut. The raw material includes S.S, carbon steel, mild steel and brass. Following are the types of blind flanges offered by us:

• Slip on
• Weld neck
• Lariont
• Socket wield
• Hared

Furthermore, these blind flanges can be easily modified in compliance with client requirement and is delivered within stipulated time frame. Below mentioned are its noteworthy features:

• High durability
• Corrosion resistant
• Dimensionally accurate

We are engaged in fabricating lap joint flanges which are known for its effectual functioning among our valued clients. These lap joint flanges are primarily used on the piping fitted with the lapped pipe or with the lap joint stub ends. The lap joint flange with the stub end is extensively used in the systems which require dismantling for inspection and cleaning. Swivel flanges and align bolt holes has the ability in easing the erection of large diameter and unusually stiff piping. These lap joint flanges are similar to slip-on flanges and have only difference that it possess curved radius at the bore and face to accommodate a lap joint stub end. These are offered in full size range and are extensively used at all pressures. These lap joint flanges are not welded and these joint flanges over the pipe. In this the bolting pressures is transferred to the gasket by the pressure of the flange against the back of the pipe lap and are otherwise fastened to it. Moreover, it is manufactured in compliance with international standards and can be modified in accordance with client requirement.

We offer threaded flanges which are highly appreciated for its dimensionally accurate and corrosion resistant features. It has the main difference is that the bore is threaded and the threaded flange is like slip-flanges. Our flanges can be easily fitted into the pipe without welding. Threaded flanges are extensively used in low –pressure services at the ambient temperature, whereas in highly explosive areas welding creates a hazard. Moreover, it can be easily customized in accordance with client requirement and is delivered on time.

We are engaged in fabricating welding neck flanges which are known for its effectual functioning among our valued clients. It is primarily used for heat coupling of pipes when there is possibility of expansion of the section while bending stress of the coupling. Following are welding neck flanges specifications:

• Material: Carbon steel A105/Rst37.2/C22.8/Q235 Stainless steel 304/304L, 316/316L, 321, etc.
• Size: 1/2"-60"
• Pressure: 150lbs-2500lbs
• Facing: RF/FF/RTJ
• Standard: ANSI, ASME/DIN/JIS/UNI/BS/GB
• Wall thickness: SCH40, STD and other wall thickness
