Angled Block with Wear-Reducing Liner for One Straight-Line Connection in Hydraulic Fracturing

A frac tree, comprising:

• one or more valves or pipes defining a vertical fluid channel for either frack fluid or flowback;
• an angled block, made of a first material, the angled block comprising two ports for fluid to pass and defining an internal cavity having at least one backwall;
• and
• a liner of wear-resistant material positioned along the at least one backwall,
• wherein the first material and the wear-resistant material and different materials.

A system, comprising:

• a frac tree comprising one or more valves or pipes defining a vertical fluid channel for either frack fluid or flowback;
• a single straight-line connection connected to the frac tree, the single straight-line connection defining a pathway for frack fluid or flowback to be respectively communicated toward or away from the frac tree, the single straight-line connection defining the pathway along only a single straight line with a constant height;
• and
• an angled block, made of a first material, the angled block comprising two ports for fluid to pass and defining an internal cavity having at least one backwall;
• and
• a liner of wear-resistant material positioned along the at least one backwall.
