SPECIALTY PRODUCTS

BuTech specializes in equipment custom designed to meet the requirements of new processes, harsh environments and severe applications. We can provide solutions for the extreme conditions of pressure, temperature, corrosion and erosion in all machineable alloys.

Manifolds
Specialty pressure manifolds minimize space requirements and reduce installation time necessary to plumb a pressure system. In addition, by reducing the number of components used in a system, manifolds reduce the number of potential leak joints.
BuTech will design and build pressure manifolds to meet specific installation, layout and pressure requirements. These manifolds are capable of withstanding pressures from vacuum to 60,000 PSI (4140 bar), and are available in a variety of materials and sizes. Among the pressure connections that can be incoprorated are low pressure compression, medium and high pressure coneand- thread, NPT, SAE, BSP and others. Transitions in system line sizes and tubing pressure series can be accomplished through a specialty manifold. These manifolds are appropriate wherever pressure tubing systems are utilized.

Custom Valves
BuTech will individually engineer valves to meet specific application requirements including metric connections and special materials. BuTech also offers a line of valves designed specifically for use in power generating plants.

TOOLS AND INSTALLATION

Safe, leak-free operation of any high-pressure system is dependent on correctly prepared and installed connections. This section outlines proper instructions for the machining and assembly of BuTech L/P, M/P, and H/P connections. In addition, this section also offers hand and power tools to make the preparation of the tubing easier.

Assembly Procedure
1. Cut tubing to desired length and de-burr, allowing extra length for proper engagement (see chart above)
2. Place gland nut and ferrule on tubing, making sure head of ferrule is toward gland nut. Push tubing into fitting until it bottoms.
3. Screw gland nut into connection until finger-tight.
4. Tighten gland nut approximately 1-1/4 turn with an open-end wrench.

Re-Assembly Procedure
1. Insert tubing with gland nut and ferrule into fitting
2. Screw gland nut into connection until finger-tight.
3. Tighten gland nut approximately 3/8 of a turn with an open-end wrench.
